Program:

 #include<stdio.h>
int maximum( int [],int ); /* function prototype */
int main(void)
{
	int values[5], i, max;
	printf("Enter 5 numbers\n");
	for( i = 0; i < 5; ++i )
		scanf("%d", &values[i] );
	max = maximum( values,5 ); /* function call */
	printf("\nMaximum value is %d\n", max );
	return 0;
}	
/**** function definition ****/
int maximum(int values[], int n)
{
	int max_value, i;
	max_value = values[0];
	for( i = 1; i < n; ++i )
		if( values[i] > max_value )
			max_value = values[i];
	return max_value;
}
 

Output:

Enter 5 numbers
5
6
4
2
3

Maximum value is 6
