Question

You want to withdraw some money from your bank account.
The program takes two numbers as input, your account balance and the amount you want to withdraw. Calculate and output the remaining balance after the withdrawal.

Sample Input
450000
9000

Sample Output
441000

Anyone got a answer for this?

Answer 1

Use subtraction.

If you follow the example you can see that
450000 - 9000 = 441000

Answer 2

Yes but it asks not only that equation, its just asking for a calculator that just does subtraction.

Answer 3

The next step in thinking about this is to understand that you would replace the literal numbers with variables.

int a;
int b;
int c;
a = 450000;
b = 9000;
c = a - b;

then print c.

cout << c;

The final revision would be to get the values for a and b as input from the user instead of assigning literal values.

cin >> a;
cin >> b;

Answer 4

Keep trying to make it work. That is the important part of the exercise. Figure out what went wrong. If there are error messages, read them. Review the lessons.

Answer 5

#include <iostream>
using namespace std;

float subtract(float a, float b);

int main() {
float num1;
float num2;
float answer;

//cout<< "Enter the first number:";
cin>>num1;
//cout<< "Enter the seconde number:";
cin>>num2;

answer = subtract(num1,num2);
cout<< answer;

return 0;
}

float subtract(float a, float b)
{
return a -b;

}
