Question

Problem H1 (Using C++)

In the main function, define four variables of type int, named: first, second, third, and total.
Write a function named getData that asks the user to input three integers and stores them in the variables first, second, and third which are in the main function.
Write a function named computeTotal that computes and returns the total of three integers.
Write a function named printAll that prints all the values in the format shown in the following sample:

1 + 2 + 3 = 6
  

Call the other three functions from the main function.

Test it once, with the values 4, 5, and 6.

Answer 1

#include<iostream>

using namespace std;  

//defination part of getData()

//it takes pointer arguments because what ever the changes made inside it ,

//that should reflect to the variables declared inside main()

void getData(int *first,int *second, int *third)

{

cout<<"Enter three values"; //asking to enter three values

cin>>*first>>*second>>*third; //input three values

}

//defination part of computeTotal()

int computeTotal(int *a, int *b, int *c)

{

return(*a+*b+*c); //return the total

}

//definationof printAll()

void printAll(int *a,int *b,int *c,int t)

{

cout<<endl<<*a<<" + "<<*b<<" + "<<*c<<" = "<<t; //print the details

}

int main()

{

int first,second,third,total; //declare four variables

getData(&first,&second,&third); //call to getData() by call by reference

total=computeTotal(&first,&second,&third); //call to computeTotal() by call by address

printAll(&first,&second,&third,total);//call tp printAll() by call by address

}
