Chapter 7, Problem 10RQE

Explanation of Solution

Passing the array as argument:

An array can be passed to a function by representing the name of the array in the function argument; the elements of the array will be copied to a new array which is declared in the function parameter.

• In a function, if an array is passed as an argument, then it refers the “address” of the first element in the memory.
• Passing the “array name” as an argument inside the function helps to know about the elements filled in the array.
• While passing the array to a function, the size of the array should be passed along with it as an argument, because by using the array alone the size of the array has not able to be computed.
  • Passing the size of array will helps to navigate the array properly.

Example:

Consider the following example which demonstrates how to pass an array as a function argument:

//Include the header file

#include<iostream>

using namespace std;

// Define the global constants for array

const int SIZE = 10;

// Define the function prototype

void displayGreaterThanN(int[], int);

//Main function definition

int main()

{

//Declare the variable to hold the number

int number;

// Define an array of integers
