CS201 Assignment Question

Programming is a nice tool that 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 papers to each student. 

Assignment Statement:

Write a menu-based program in C++ that will take input from the user(teacher) and fulfill the following requirements.

• There should be a menu that allows selecting the grade of the class. 
• Created questions should be mixed type (addition and subtraction).
• User will give the number of questions that will be generated for a paper.
• The ratio of addition and subtraction questions is not fixed. It will random, a paper can have more questions of one type than other. See the 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 the required application is given below as a 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 the case of addition operation, the operand (number) on left side of the 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 returns 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 numbers with the help of the 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 the value of N will be 100 then range of randomly generated numbers will be 0 to 99. 
• If you want to control the range of random numbers between 10 to 19 then following formula will help.
• [10 + rand() % (19 – 10 + 1)]
