Passing Array As An Argument

/*Remember, array is always passed by address to a function. Thus, any change made by the function (to anairay) i s shown in the original array as well.*/

#include<stdio.h>

void sqArr(int[]); // function to square the contents of an array

void main()

{

int arr[5]=(1,2,3,4,5); 

int i;

printf("Array before function call: ");

for(i=0;i<5;i++)

{

printf("%d", arr[i]);

}

sqArr(arr);

printf("\nArray after function call: ");

for(i=0;i<5;i++)

{

printf("%d", arr[i]);

}

}

void sqArr(int a[])

{

int i;

for(i=0;i<5;i++)

}

}

OUTPUT:

Array before function call: 12345 

Array after function call: 149 16 25
