i was expecting a output asking score but no printf fnx is working.

#include<stdio.h>
float percentage(float a, float b, float c);

float main(){
    float a,b,c;
    printf("enter sci marks: ");
    scanf("%f",&a);
    printf("enter maths marks: ");
    scanf("%f",&b);
    printf("enter sans marks: ");
    scanf("%f",&c);
    float var = percentage(a,b,c);
    printf(" percentage = %f", var);
    return 0;
}
float percentage(float a,float b,float c){
    float var = (a + b + c)/3.0 ;
    return var; 
}

was expecting the program to ask for all three inputs and then give percentage.
