Dev C++
Objectives:
To enable students to understand and
practice the concepts of:
 Variables
and operators
 Loops or
repetition structures
 Ifelse
statements
 Functions
 Random
number generation
 Control
random number in specific range
You have to submit only.cpp file on the assignments interface of CS201 at
VULMS. Assignment
submitted in any other format will not be accepted and will be graded zero
marks.
Please note again, assignment submitted
other than .cpp format will get zero marks.
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 consolebased
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 menubased 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, ifelse,
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)]
