why I didn't get any floating points?

Question

I am writing a program to calculate an average fuel consumption from the given total distance (integer value) traveled (in km) and spent fuel (in liters).

Code

#include <stdio.h>

int main(){
    int distance;
    int noOfLiters;
    printf("Enter The distance:");
    scanf("%d",&distance);
    printf("Enter The Fuel Spent:");
    scanf("%d",&noOfLiters);

    float avgFuelConsumption = noOfLiters/distance;

    printf("Average Fuel Consumption :  %f", avgFuelConsumption);
}

Output


Enter The distance:50
Enter The Fuel Spent:5
Average Fuel Consumption :  0.000000

The Average Fuel Consumption should be 0.1, but I got 0, Why?

Cast one of the numbers to be `float` when you divide. Integer division of small/large will always give you zero... — Fe2O3, Aug 09 '22 at 06:07
Because of the types. An int divided by another int will use integer division, throwing away the remainder. You must cast either noOfLiters or distance to float first. — qrsngky, Aug 09 '22 at 06:07

Or use floating point values for the `distance` and `noOfLiters`. — Some programmer dude, Aug 09 '22 at 06:08
On another note, unless you have specific requirements there's almost never any need to use `float` instead of `double`. — Some programmer dude, Aug 09 '22 at 06:09

Change

float distance;
float noOfLiters;

"total distance (integer value) " this is given , so I must only have yo change noOfLiters, Thank you – Sandeepa_Dilshan Aug 09 '22 at 06:09
That's not enough, the conversion specifiers in `scanf` need to be changed too. – Jabberwocky Aug 09 '22 at 06:18
If he doesn't change it, he'll get an error, I thought you'd notice it – Mert Aug 09 '22 at 06:20
