Thread: Pass by reference

Hi, I'm having a problem using pass by reference to pass arrays and floats through functions. This is my assignment:
http://www.comp.dit.ie/mcollins/ft22...signment2.html

The code I've got so far (which is pass by value as its all i can do):

Code:

#include <stdio.h>
#define SIZE 5

main()
{
    int i;
    float temps[SIZE];

    printf("\nPlease enter %d float numbers: \n\n", SIZE);
    
    read(temps);
    display(temps);
    
}            

read(float temps[])
{
    int i;
    
    for (i = 0; i < SIZE; i++)
    {
        scanf("%f", &temps[i]);
    }
}

display(float temps[])
{
    int i;
    
    for (i = 0; i < SIZE; i++)
    {
        printf("%f ", temps[i]);
    }
}

How do I change this to pass by reference?

Many thanks in advance.
