Read and print content of an integer array in C++ language

In this article, we will discuss the concept of Read and print content of an integer array in C++ language

In this post, we are going to learn how to write a program to input and print integer elements in single dimensional array in C++ language using for, while and do-while loop

Code to input and print integers of an array

Code to input and print integers in an array using for loop

In this code, we are going to learn how to input and print integer elements in single dimensional array using for loop in C++ language

Program 1

#include <iostream>
#include <conio.h>
#define MAX_SIZE 100//maximum size of the array

using namespace std;

int main()
{
    int arr[MAX_SIZE];//Declare size of the array as MAX_SIZE
    int i,len;
    cout<<"Enter size of the array\n";//Read size of the array
    cin>>len;

    cout<<"Enter "<<len<< "elements in the array\n";
    //Read elements of the array from user

    for(i=0; i<len; i++){
            cout<<"Enter element for array index arr["<<i<<"] : ";
        cin>>arr[i];
    }
    cout<<"\nEntered elements of an array\n";
    //print given elements of the array by user
    for(i=0; i<len; i++){
            cout<<"Entered element in array index arr["<<i<<"] : ";
       cout<<arr[i];
       cout<<"\n";
    }
    getch();
    return 0;
}

When the above code is executed it produces the following result

Output 1

Code to input and print integers in an array using while loop

In this code, we are going to learn how to input and print integer elements in single dimensional array using while loop in C++ language

Program 2

#include <iostream>
#include <conio.h>
#define MAX_SIZE 100//maximum size of the array

using namespace std;

int main()
{
    int arr[MAX_SIZE];//Declare size of the array as MAX_SIZE
    int i,len;
    cout<<"Enter size of the array\n";//Read size of the array
    cin>>len;

    cout<<"Enter "<<len<< "elements in the array\n";
    //Read elements of the array from user

    i=0;
    while( i<len){
            cout<<"Enter element for array index arr["<<i<<"] : ";
        cin>>arr[i];
         i++;
    }
    cout<<"\nEntered elements of an array\n";
    //print given elements of the array
    i=0;
    while(i<len){
            cout<<"Entered element in array index arr["<<i<<"] : ";
       cout<<arr[i];
       cout<<"\n";
        i++;
    }
    getch();
    return 0;
}

When the above code is executed it produces the following result

Output 2

Code to input and print integers in an array using do-while loop

In this code, we are going to learn how to input and print integer elements in single dimensional array using do-while loop in C++ language

Program 3

#include <iostream>
#include <conio.h>
#define MAX_SIZE 100//maximum size of the array

using namespace std;

int main()
{
    int arr[MAX_SIZE];//Declare size of the array as MAX_SIZE
    int i,len;
    cout<<"Enter size of the array\n";//Read size of the array
    cin>>len;

    cout<<"Enter "<<len<< "elements in the array\n";
    //Read elements of the array

    i=0;
    do{
            cout<<"Enter element for array index arr["<<i<<"] : ";
        cin>>arr[i];
         i++;
    }while( i<len);
    cout<<"\nEntered elements of an array\n";
    //print given elements of the array
    i=0;
   do{
            cout<<"Entered element in array index arr["<<i<<"] : ";
       cout<<arr[i];
       cout<<"\n";
        i++;
    } while(i<len);
    getch();
    return 0;
}

When the above code is executed it produces the following result
