Printing an array of strings through user input in C++

In this article, we will discuss the concept of Printing an array of strings through user input in C++

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

Code to print Strings of an array

Code to print Strings of an array using for loop

In this code, we are going to learn how to print string 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;
    cout << "Enter array length:" << endl;
    cin>>len;
    cout << "Enter your "<<len<<" Strings:" << endl;
    string* str=new string[len];//Declaring one dim string array
    for(int i=0; i<len; i++ ){

        cin>>str[i];//Taking string as input from user
    }

    cout << "\nentered "<<len<<" Strings:" << endl;
    for(int i=0; i<len; i++ ){
         cout << "Print string stored in index "<<"str["<<i<<"]"<<":";
        cout<<str[i]<<endl;//Printing string as input from user
    }
getch();
    return 0;
}

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

Enter array length:
4
Enter your 4 strings:
Obama
Push
Trump
Regan

entered 4 Strings
Print string stored in index str[0]:Obama
Print string stored in index str[1]:Push
Print string stored in index str[2]:Trump
Print string stored in index str[3]:Regan

Code to print Strings of an array using while loop

In this code, we are going to learn how to print string 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;
    cout << "Enter array length:" << endl;
    cin>>len;
    cout << "Enter your "<<len<<" Strings:" << endl;
    string* str=new string[len];//Declaring one dim string array
    int i=0;
    while(i<len){

        cin>>str[i];//Taking string as input from user
         i++ ;
    }

    cout << "\nentered "<<len<<" Strings:" << endl;
   i=0;
    while(i<len){
         cout << "Print string stored in index "<<"str["<<i<<"]"<<":";
        cout<<str[i]<<endl;//Printing string as input from user
         i++ ;
    }
getch();
    return 0;
}

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

Enter array length:
3
Enter your 3 strings:
Mayu
Kaju
Thanu

entered 3 Strings
Print string stored in index str[0]:Mayu
Print string stored in index str[1]:Kaju
Print string stored in index str[2]:Thanu

Code to print Strings of an array using do-while loop

In this code, we are going to learn how to print string 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;
    cout << "Enter array length:" << endl;
    cin>>len;
    cout << "Enter your "<<len<<" Strings:" << endl;
    string* str=new string[len];//Declaring one dim string array
    int i=0;
    do{

        cin>>str[i];//Taking string as input from user
         i++ ;
    }while(i<len);

    cout << "\nentered "<<len<<" Strings:" << endl;
   i=0;
    do{
         cout << "Print string stored in index "<<"str["<<i<<"]"<<":";
        cout<<str[i]<<endl;//Printing array of string 
         i++ ;
    }while(i<len);
getch();
    return 0;
}

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

Enter array length:
2
Enter your 2 strings:
Colombo
Jaffna

entered 2 Strings
Print string stored in index str[0]:Colombo
Print string stored in index str[1]:Jaffna
