passing array as arguments specx range of array at main func?is the foll snippet wrong
float avg(a,size) float a[]; int size; { int i; float sum=0; for(i=0;i<size;i++) sum+=a[i]; return(sum/size); } //main func #define NUM 25 float a[NUM]; avg(a,NUM);

your first line should be float avg(float a[],int size) and then you dont need second and third line.

A minor modification is all that is needed here:
#include <iostream>
#define NUM 25
float avg(float a[], int size)
{
float sum = 0;
for(int i = 0; i < size; i++)
sum += a[i];
return(sum / size);
}
// main func
int main()
{
float a[NUM];
// Get value for each array element
// 25 inputs needed (as defined by NUM)
for(int i = 0; i < NUM; i++)
std::cin >> a[i];
// Calculate & display avg
std::cout << " AVG: " << avg(a, NUM);
}
