Write a C++ program that performs the following tasks:
1- Print your name, VU id, and list of courses you have selected in current semester.
2- Print the names of all courses you have selected in the current semester.
3- Add first numeric digit of your VU id to the total number of courses selected.
4- Display the result of sum on the screen.
5- Print “Welcome to CS201-Introduction to Programming” by using WHILE loop. Number of iterations of WHILE loop must be equal to sum calculated in point 4.
For example, suppose the student id is BC123456781. Then by adding first digits of vu id=1, with number of courses (suppose =4), we get sum= 5.
Sum = first digits of vu id + number of courses
5 = 1 + 4
In this case, program should print “Welcome to CS201-Introduction to Programming” 5 times.

Assignment
Programming is a nice tool which can be used to make our life easier. With the help of programming we can do many things auto generated and efficiency. As a programmer first task of this semester is given to you is develop a console-based application for school teachers. This application will auto generate questions for Grades 1, 2, 3, 4 and 5. Using this application teacher will be able to give different paper to each student.
Assignment Statement:
Write a menu-based program in C++ that will take input from user(teacher) and fulfill following requirements.
• There should be a menu that allow to select grade of class.
• Created questions should be mixed type (addition and subtraction).
• User will give number of questions that will be generated for a paper.
• Ratio of addition and subtraction questions is not fixed. It will random, a paper can have more questions of one type than other. See sample output screenshot.
• Number of minimum and maximum digits in paper of grade 1 will be two.
• Number of minimum and maximum digits in paper of grade 2 will be three.
• Number of minimum and maximum digits in paper of grade 3 will be four.
• Number of minimum and maximum digits in paper of grade 4 will be five.
• Number of minimum and maximum digits in paper of grade 5 will be six.
• Screen shot of required application is given below as simple output.
• Most critical requirement is, the operand (number) on left side of subtraction sign must be larger than the number on right side of sign (operator). This requirement is highlighted in sample screenshot too.
• In case of addition operation, the operand (number) on left side of addition sign can be larger or smaller from the number on right side of sign (operator).
Solution instructions:
• Variables, loops, if-else, rand() function with % operator, functions (one which return a value and one which do not return a value) will help you to solve the problem.
• Use rand() function to generate a random number. You can control the range of number with the help of modulus (%) operator.
• To use rand() function you must include “stdlib.h” header file.
• To control the range of random number rand() % N can help, if value of N will be 100 then range of randomly generated number will be 0 to 99.
• If you want to control the range of random number between 10 to 19 then following formula will help.
o [10 + rand() % (19 – 10 + 1)]
Sample output:

Assignment Statement:
Assume you are working as a sports data analyst for a university named “ABC University”. Your job is to collect data of different players and judge their performance. Based on the data collected from players, their performance for a given season will be analyzed and comparison among players of the team will be made for selection. For this purpose, you are required to write a program in C++ that will create a class named “Sports”. The class will create a file named “Sample.txt” in the current directory. You will use file handling mechanism for entering player’s information. Following tasks are required:
• You are required to create a class named “Sports”.
• Declare three data members of Sports class named playername, game_name and total_wins with appropriate data types.
• The class will consist of 6 functions named input_file(), read_file(), notstartingwithA(), lower(), upper() and digit() respectively along with a default constructor. The description of each function is given with the screenshots in the “Sample output”.
• In the main() function an object of the class “Sports” will be created and it will be used along with switch statement to call the functions mentioned above. i.e. input_file(), read_file(), notstartingwithA(), lower(), upper() and digit().
• Initially a menu will be displayed consisting of different choices as shown below:
• User will enter a choice from the choices given in the menu. Output of each selected number is shown in the output samples below for detailed description.
Sample Output:-
1.
• In the first step the following menu will appear at the output screen.
[image: j4xkXhD.png]
• User will first populate file “Sample.txt” before reading the file as given below.
[image: 4owoOn0.png]
• The function named input_file() will take input from user and store it in the file named “Sample.txt”. If a user wants to enter second record, the first record in the file will not be deleted; rather new data will be added at the end of the file.
[image: 7vyotl9.png]
• The function read_file() will read all data stored in the file “Sample.txt” from start to end.
[image: FTG96c7.png]
• The function notstartingwithA() will check the file and find all lines of the file “Sample.txt” that are not started with character “A” including blank lines. E.g. the above data will consists of 3 lines in the file. notstartingwithA() function will count all those line and display the count on output screen as given below.
[image: Lq9KOrP.png]
• The function lower() will find all those lines that are started with lower characters in the file “Sample.txt” and display the count on outputs screen as given below.
[image: lJPXTvF.png]
• The function upper() will find all those lines that are started with an upper case character in the file “Sample.txt” and display the count on outputs screen as given below.
[image: uuSzZSd.png]
• The function digit() will find all those lines that are started with a digits in the file “Sample.txt” and display the count on output screen.

An array of arrays is known as two-Dimensional array. In C++ it is also known as matrix. A matrix can be represented as a table of rows and columns. Like single dimensional arrays, we can store same type of data in it. Elements stored in array can be accessed using array index. Index starts from [0][0]. Means the index of row and column starts from 0. Following is an example of a two-dimensional array declaration and initialization having 3 rows and 3 columns.
int mularray[3][3] = { //Declaration and initialization of a 2D Array
{1, 2, 3},
{5, 7, 9},
{0, 2, 4}
};
// The value of mularray [0][0] is 1
// The value of mularray [0][1] is 2
// The value of mularray [1][2] is 9
// The value of mularray [2][1] is 2
Problem Statement
Write an option-based program in C++ which should show following four options to the user at the start of application:
Press 1 to populate a two-dimensional array with integers from 1 to 100.
Press 2 to display the array elements.
Press 3 to display the largest element present in the array along with its row and column index.
Press 4 to find and show the transpose of the array.

Use random number function to populate the array i.e. rand( ). Range should be 1 to 100.
Hint: use srand( ) function before rand( ) to seed the random number. In loop, rand( ) may generate same numbers so you should use srand(time(0)) before rand( ) to generate different random numbers. To use time(0) you may need to include time.h header file.
Switch statement will be implemented to perform multiple conditions and to perform different actions based on the conditions. i.e. Option 1, 2, 3 and 4.
Write user defined functions to perform tasks given in options. Following function names should be used for consistency.
To populate the array
poulateArray( );
To display all elements of Array
showElements( );
To show largest element in the array
showLargestElement( );
To show transpose of the array
transposeArray( );
Screenshots for Guidance:
1 If the user choses any option other than “1” at the start when the array is empty, the user should get a message like “Sorry the array is empty, first populate it by pressing 1 to perform this task ". See the following sample output:

2 Upon pressing 1, a message like “Array has been populated successfully!" should be displayed. See the following sample output:

4 Largest number along with its row and column number can be found by pressing 3. Similarly, if the user presses 4 transpose of the array should be displayed. See the sample outputs for both options:
