Demo Code

#include <stdio.h>

int main(void)
{
  int grades[10];                          // Array storing 10 values
  unsigned int count = 10;                 // Number of values to be read
  long sum = 0L;                           // Sum of the numbers
  float average = 0.0f;                    // Average of the numbers

  printf("\nEnter the 10 grades:\n");      // Prompt for the input

  // Read the ten numbers to be averaged
  for(unsigned int i = 0 ; i < count ; ++i)
  {/*from  w  w  w .  j  a  v a2  s.c  om*/
    printf("%2u> ",i + 1);
    scanf("%d", &grades[i]);               // Read a grade
    sum += grades[i];                      // Add it to sum
  }
  average = (float)sum/count;              // Calculate the average
  // List the grades
  for(unsigned int i = 0 ; i < count ; ++i)
    printf("\nGrade Number %2u is %3d", i + 1, grades[i]);

  printf("\nAverage of the ten grades entered is: %.2f\n", average);
  return 0;
