C++ program to read and print array of Strings

In this article, we will discuss the concept of C++ program to read and print array of Strings

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

Code to read and print Strings of an array

Code to read and print Strings of an array using for loop

In this code, we are going to learn how to read and 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 a string array
    for(int i=0; i<len; i++ ){
cout << "Read array of string for index "<<"str["<<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:
3
Enter your 3 strings:
Read array of strings for index str[0]: India
Read array of strings for index str[1]: USA
Read array of strings for index str[2]: France

Entered 3 Strings
Print string stored in index str[0]: India
Print string stored in index str[1]: USA
Print string stored in index str[2]: France

Code to read and print Strings of an array using while loop

In this code, we are going to learn how to read and 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 a string array
    int i=0;
    while( i<len ){
cout << "Read array of string for index "<<"str["<<i<<"]"<<":";
        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:
4
Enter your 4 strings:
Read array of strings for index str[0]: Run
Read array of strings for index str[1]: Stop
Read array of strings for index str[2]: Come
Read array of strings for index str[3]: Sit

Entered 3 Strings
Print string stored in index str[0]:Run
Print string stored in index str[1]:Stop
Print string stored in index str[2]: Come
Print string stored in index str[3]: Sit

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

In this code, we are going to learn how to read and 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 a string array
    int i=0;
   do{
cout << "Read array of string for index "<<"str["<<i<<"]"<<":";
        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 string as input from user
         i++;
    } while(i<len );
getch();
    return 0;
}

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

Enter array length:
5
Enter your 5 strings:
Read array of strings for index str[0]: Cat
Read array of strings for index str[1]: Dog
Read array of strings for index str[2]: Pig
Read array of strings for index str[3]: How
Read array of strings for index str[4]: Goat

Entered 5 Strings
Print string stored in index str[0]:Cat
Print string stored in index str[1]:Dog
Print string stored in index str[2]: Pig
Print string stored in index str[3]: How
Print string stored in index str[4]: Goat
