Question

int main()
{
float d;
d =50 - ( 50/100*15);
cout << d;
}

output is 50;
it should be 42.5

Answer 1

(50.0/100.0*15.0)

Answer 2

faizan moriani ,

the reason for your problem is that the numbers in the expression (50 / 100 * 15) are all integer numbers. so 50 / 100 => 0 and 0 * 15 => 0, so finally 50 - 0 => 50.

Answer 3

by using only integer literals you get the result as integer (0*15 == 0)
