Chapter 7, Problem 88RQE

Program Plan Intro

Passing array to a function:

An array can be passed to a function; to pass an array to a function then the name or address of the array should be passed as the argument to the function.

• The called function should receive the array through defining another array in the parameter.

Example:

The following program demonstrates how to pass an array to a function:

// Main function

int main()

{

//Declaring the array size

int array = 4;

//Initializing the array

int num[array] = {3, 2, 1, 4}

//Define function prototype

shownum(number, array_val);

//Return the value

return 0;

}

//define the function

//Pass the array as argument

void shownum(int numbers[], int value)

{

//Execute the for loop

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

/*print the values of numbers present in the index

Value*/

cout << numbers[i] << “ ” << endl;

}

In the above example, the array “numbers” has been passed inside the function “shownum()” as an argument and the function definition of “shownum” receives the array through another array named “numbers” with undefined size.
