Question

An international phone call is billed by the minute according to this scheme: Calls up to 10 minutes cost a flat $5. Calls over 10 minutes but less than 30 cost $.50 per minute. Calls 30 minutes or longer cost a base of $15.00 plus $.30 per minute over 30.

Write a program to read in the duration of a call as an integer and output the total cost as a decimal. Do not worry about making it look like money.

Code:

#include <iostream>

using namespace std;

int main()

{

//YOUR_CODE

}

Answer 1

using namespace std;

#include <iostream>

Go()

{

int minutes=-1;

float cost;

while (minutes<0)

{

cout << "How many minutes ??? :>";

cin >> minutes;

}

if (minutes<=10)

{

cost=5;

}

else if ((minutes>10) && (minutes<30))

{

cost = minutes * 0.5;

}

else

{

cost = 15 + (minutes-30)*0.3;

}

cout << " cost is " << cost << endl;

}

int main()

{

Go();

}
