Write a C++ program to swap first and last element of an integer 1-d array.

Write a C++ program to swap first and last element of an integer 1-d array.

Program Code:

#include<iostream>

using namespace std;

int main()

{

int array[25];

int number;

int i, j, temp;

cout<<"Enter number of elements you want to insert into given array : ";

cin>>number;

cout<<endl;

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

{

cout<<"Element "<<i+1<<":";

cin>>array[i];

cout<<endl;

}

temp = array[0];

array[0] = array[number - 1];

array[number - 1]= temp;

cout<<"Array after swapping its first and last element is :"<<endl;

for(j=0;j<number;j++)

{

cout<<array[j]<<" ";

}

return 0;

}

The program output is tested on www.jdoodle.com

Output:

Enter number of elements you want to insert into given array : 5

Element 1: 15

Element 2: 14

Element 3: 22

Element 4: 34

Element 5: 55

Array after swapping its first and last element is :

55 14 22 34 15
