One Dimensional Array - Question 8

In this question, we will see how to input 10 numbers in a one dimensional integer array and interchange the consecutive numbers in it in C++ programming. To know more about one dimensional array click on the one dimensional array lesson.

Q8) Write a program in C++ to input 10 numbers in a one dimensional integer array and interchange the consecutive numbers in it. That is, interchange a[0] with a[1], a[2] with a[3], a[4] with a[5] and so on.

Single Dimension Array Question 8

Program

#include <iostream>
#include <conio.h>

using namespace std;

int main()
{
    int a[10], i,t;

    cout<<"Enter 10 numbers\n";
    for(i=0; i<10; i++)
    {
        cin>>a[i];
    }

    //Interchanging the consecutive numbers in array
    for(i=0; i<10; i=i+2)
    {
        t=a[i];
        a[i]=a[i+1];
        a[i+1]=t;
    }

    cout<<"\nModified array after interchanging the consecutive numbers\n";
    for(i=0; i<10; i++)
    {
        cout<<a[i]<<" ";
    }
    return 0;
}

Output

Enter 10 numbers
18
12

10
15
45
38
72
64
11

Modified array after interchanging the consecutive numbers
