Passing Array to functions

Passing Array to Functions

When an array is passed to a function as an argument, the array’s address is actually passed, rather than the values of the elements in the array. If the function modifies the array values, the array will be modified, since there is only one copy of the array in memory.

To pass one dimensional array to the following rules are considered:

1.Function must be called by using only the name of array. It need not include size of array.

For Example: Consider the array list:

Int list[ ]= {0,4,5,-8,17,301};

Let biggest be the called function. To pass the array list and an integer variable to the called function, it can be written as:

Biggest(list,n);

To pass array alone to the called function, it can be written as:

Biggest(list);

2.The function header must have the data type of the array. Size of array need not be specified. However empty square brackets must be used, to specify the parameter as an array. Function definition can have formal parameters.

For Example: the function header for the called function biggest can be written as: int biggest(int array[], int size)

3.Function prototype must specify the argument is an array.

For Example: int biggest(int array[], int size);

The difference between function header and function prototype is only semicolon(;).
