Program to fill and print an array of characters from user in C++

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

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

Code to fill and print characters of an array

Code to  fill and print characters of an array using for loop

In this code, we are going to learn how to fill and 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<<"\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 executed, it produces the following result

Code to  fill and print characters of an array using while loop

In this code, we are going to learn how to fill and print character 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<<"\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;
}

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

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


    getch();
    return 0;
}
