kaleidoscopes

Question

Help why getting int value
Not decimal

#include <iostream>
using namespace std;

int main() {
int kaleidoscopes;
cin>>kaleidoscopes;
float i,b;
int j= kaleidoscopes*5;

if(kaleidoscopes>=1){
b=(10/100)*j;

i = (7/100)*b;

}
float d=(j-b)+i;
cout<<d;
}

Answer 1

10 / 100 = 0
7 / 100 = 0

If you divide two integers, the result is truncated to an int.
Solution 1: use at least one float operand then the other one is implicitly converted to float.
10.0 / 100
Solution 2: use float variables, and in your compound formula make sure you start the operation with one float type at least
float_var * 10 / 100
