Question

The use of computers in education is referred to as computer-assisted instruction (CAI). In this exercise, you will write a program that will help an elementary school student learn addition, subtraction, multiplication and division. Allow the user to pick a type of arithmetic problem to study: 1 addition problems only 2 subtraction problems only 3 multiplication problems only 4 division problems only 5 random mixture of all types The program should then prompt the user with a question, such as: How much is 6 times 7? The student inputs the answer. The program checks the student

//C ++ program for kids maths learning

#include <iostream>
#include <ctime>
#include <math.h>
#include <string>
using namespace std;

//function prototypes
bool addtionProblem(int ,int);
bool subtractionProblem(int ,int );
bool divisionProblem(int ,int);
bool multiplicationProblem(int ,int);
bool randomMixture(int ,int);
void generateProblem(int);

   }while(ch=='y' ||ch=='Y');
   //pause the console out put until user enters
   //a key to close the program
   system("pause");

//Menu that prompts user to enter choice and
//returns the user choice .Prompt until user
//enter a valid choice.

}

//Generate two random numbers and based on user choice
//and called appropriate method using switch case
//and print appropriate message for user answer.
