C++ Program to print an array of characters from user

In this article, we will discuss the concept of C++ Program to print an array of characters from user

In this post, we are going to learn how to write a program to print an array of characters (character elements in single dimensional array) using for, while and do-while loop in C++ language

Code to print characters of an array

Code to print characters of an array using for loop

In this code, we are going to learn how to print character elements (user input) in single dimensional array using for loop in C++ language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int len;//Declare variable for length
    cout<<"Enter array length\n";
    //Ask input from the user for length
    cin>>len;
//Reading the input for length
 char ch_arr[len];
    //Character  1D array declaration


    cout<<"\nEnter the characters for array\n";
    //Ask to enter the characters

    for(int i=0; i<len; i++){
            cout<<"ch_arr["<<i<<"]:";
        cin>>ch_arr[i];
    }//Reading char elements using for loop

    cout<<"\n*** print the array of characters ***\n";
    cout<<"\nEntered characters are:\n";
    for(int i=0;  i<len; i++){
            cout<<"ch_arr["<<i<<"]:"<<ch_arr[i];
cout<<"\n";
        //Display the entered characters
    }


    getch();
    return 0;
}

When the above code is execute, it produces the following result

C++ Program to print an array of characters from user — print an array of characters

Code to print characters of an array using while loop

In this code, we are going to learn how to print chracter elements (user input) in single dimensional array using while loop in C++ language

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int len;//Declare variable for length
    cout<<"Enter array length\n";
    //Ask input from the user for length
    cin>>len;
//Reading the input for length
 char ch_arr[len];
    //Character  1D array declaration


    cout<<"\nEnter the characters for array\n";
    //Ask to enter the characters

    int i=0;
    while(i<len){
            cout<<"ch_arr["<<i<<"]:";
        cin>>ch_arr[i];
         i++;
    }//Reading char elements using while loop
cout<<"\n*** print the array of characters ***\n";
    cout<<"\nEntered characters are:\n";
    i=0;
    while( i<len){
            cout<<"ch_arr["<<i<<"]:"<<ch_arr[i];
cout<<"\n";
        //Display the entered characters
        i++;
    }


    getch();
    return 0;
}

When the above code is execute, it produces the following result

Code to print characters of an array using do while loop

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

Program 3

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int len;//Declare variable for length
    cout<<"Enter array length\n";
    //Ask input from the user for length
    cin>>len;
//Reading the input for length
 char ch_arr[len];
    //Character  1D array declaration


    cout<<"\nEnter the characters for array\n";
    //Ask to enter the characters

    int i=0;
    do{
            cout<<"ch_arr["<<i<<"]:";
        cin>>ch_arr[i];
         i++;
    }while(i<len);
    //Reading char elements using do-while loop

    cout<<"\nEntered characters are:\n";
    i=0;

    cout<<"\n*** print the array of characters ***\n";
   do{
            cout<<"ch_arr["<<i<<"]:"<<ch_arr[i];
cout<<"\n";
        //Display the entered characters
        i++;
    } while( i<len);


    getch();
    return 0;
}

When the above code is execute, it produces the following result
