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.

    • [10 + rand() % (19 – 10 +
      1)]
