Question

Given that two int variables, total and amount, have been declared, write a sequence of statements that: initializes total to 0 reads three values into amount, one at a time. After each value is read in to amount, it is added to the value in total (that is, total is incremented by the value in amount). Instructor Notes: Do not use any looping. Just use three cin statements and three calculations.

Answer 1

Answer:

Following are the program in C++ language :

#include <iostream> // header file

using namespace std; // using namespace

int main() // main method

{

   int amount,total=0; // two int variable declaration

   cout<<" enter amount:";

   cin>>amount; // read input amount first time

   total=total+amount; // first calculation

   cout<<" enter amount:";

   cin>>amount; //read input amount second time

   total=total+amount;// second calculation

   cout<<" enter amount:";

   cin>>amount;// read input amount third time

   total=total+amount;// third calculation

   cout<<"total:"<<total; // display total

  return 0;

}

Output:

enter amount:12

enter amount:12

enter amount:12

total:36

Explanation:

Following are the explanation of program which is mention above

• Declared the two variable total and amount of int type .
• Initialize the variable total to "0".
• Read the 3 input in "amount" variable in one by one by using cin function and adding their value to the "total "variable .
• Finally display the total.
