my variable doesnt seem to catch and keep the highest score...

when you go through the program, it doesnt seem to catch the highest user entered score, its weird cos im not good at this yet, im just chucking code at it but nothing as come from it....
would really appreciate a few pointers or nudges in the right direction, or a solution but definatley informing me of where ive gone wrong .

#include <stdio.h>
#define BIG 100

/* Declare an array to hold expenses, and a counter variable */

int grades[4], i,big, low;
int count, sum, avg;
main()
{
/* Input data from keyboard into array */
printf("Please enter your students marks to find out average, highest and lowest\n\n");
for (count = 0; count < 20; count++)
{
printf("Enter Grade %d: ", count);
scanf("%d", &grades[count]);
sum=sum + grades[count];
avg=sum / 20;
big=grades[0];
{
if(grades[count]>BIG)
big=grades[count];
else
if(grades[count]<low)
low=grades[count];
}
printf("\nLargest Number is=%d\nSmallest Number is=%d ",big,low);

}


printf("\n\nThe sum of all the grades is: %d", sum);
printf("\nThe Average grade is: %d\n\n", avg);

}

That's because you're setting big value to grades[0] each time the program loops.

line 18: big=grades[0];

Put that before your for loop.

Also, I believe int grades[4] and for (count = 0; count < 20; count++) will cause a runtime error.
