Unable to Calculate Correct Average

C language, stdio.h library

Sample code:

float avg;
avg = 3 / 2;
printf("Average: %.2f", avg);

From the code above I expect the following output:

Average = 1.50

But instead I get:

Average = 1.00

Why is this? And how do I get the correct output?

Solution 
  • #include <stdio.h>

int main(void) {
float avg;
avg = (float) 3 / 2;
printf("Average: %.2f", avg);

    return 0;
}
