/*

This program is to pass the entire array to a function

*/

#include <stdio.h>

#include <conio.h>

int maximum(int[],int);//function prototype, 1st parameter is array and the second is integerint main()

{

int a[100],i,n,max=0;

printf("Enter the numbers");

scanf("%d",&n);//get the index number

for(i=0;i<n;i++)//get the array elements

{

scanf("%d",&a[i]);

}

max=maximum(a,n);//function call

printf("Maximum number is %d",max);

getch();

return 0;

}int maximum(int b[],int a)

//function implementation

{

int i,max=b[0];

for(i=0;i<a;i++)

if(b[i]>max)

max=b[i];

return max;

}

In the function call ie

max=maximum(a,n)where a is the array and n is the number of array elements

the above line can be written as

max = maximum(&a[0],n)

since the array is just a memory address, it is enough to mention the base address (address of the first element) of the array

so the array name is just equivalent to the base address

in the above example

a means &a[0]
