Output always 0

[crowandrabbit]

Hi,
When I enter 20 for weight_t and 10 for weight_r, I want each of them to divide by 100 which would give me a result of .20 and .10. However, it always outputs 0 not matter what number I put in and I cant figure out why.

Can anybody explain to me what is wrong with my program?

#include <iostream>
using namespace std;

int main () {
	float weight_t = 0, weight_r = 0, weight_l = 0, weight_a = 0;	

	cout << "Enter quiz weight percentage" << endl;
	cin >> weight_t;
	cout << "Enter design weight percentage" << endl;
	cin >> weight_r;
	cout << "Enter critique weight percentage" << endl;
	cin >> weight_l;
	cout << "Enter critique weight percentage" << endl;
	cin >> weight_a;

    while (weight_t != 0)
        weight_t = weight_t/100;
    while (weight_l != 0)
        weight_l = weight_l/100;   
    while (weight_r != 0)
        weight_r = weight_r/100;
    while (weight_a != 0)
        weight_a = weight_a/100;
        
    cout << "weight_t is " << weight_t << endl;
    cout << "weight_r is " << weight_r << endl;
        
    return 0;
}

Change the while statements to if statement.

while (weight_t != 0)

will always be true, therefore it will continue to loop until weight_t is 0.

[integralfx]

    while (weight_t != 0)
        weight_t = weight_t/100;

This loop will keep dividing weight_t by 100, until it reaches 0. Hence, why it will always output 0 for every number you input.
