Question

Here is my code:

//preprocessor files
#include <stdio.h>
#include <stdlib.h>

void printScores(float scores[]);

int main()
{
   char s_name[] = "ECPI University";
   float scores[6] = {78.7, 98.4, 100.0, 96.5, 100.0, 88.8};
   float average = 0.0;
   int counter;
  
   printScores(scores);
  
   for(counter = 0; counter < 6; counter++){
       average += scores[counter];
   }  
  
   average /= float(6); ===============this is where i am getting the error   
  
   printf("\nAt %s, your class average is %.1f.", s_name, average);
   system("pause");
   return 0;
}

void printScores(float scores[6]){
   int counter;
  
   printf("Here are your scores:\n\n");
   for(counter =0; counter < 6; counter++){
       printf("%.1f\n,", scores[counter]);
   }
   return;
}

Why am I getting this error:   [Error] expected expression before 'float' for the code portion above i have commented to the right of?

//preprocessor files
#include <stdio.h>
#include <stdlib.h>


void printScores(float scores[]);

int main()
{
   char s_name[] = "ECPI University";
   float scores[6] = {78.7, 98.4, 100.0, 96.5, 100.0, 88.8};
   float average = 0.0;
   int counter;
  
   printScores(scores);
  
   for(counter = 0; counter < 6; counter++){
       average += scores[counter];
   }  
  
   average /= 6.0; 
  
   printf("\nAt %s, your class average is %.1f.", s_name, average);
   system("pause");
   return 0;
}

void printScores(float scores[6]){
   int counter;
  
   printf("Here are your scores:\n\n");
   for(counter =0; counter < 6; counter++){
       printf("%.1f\n,", scores[counter]);
   }
   return;
}


Note: float value for 6 is 6.0
So, You can directly use 6.0

If you still want to use float keyword then use below statement
average /= (float)6;
