Display characters in a string using C++ language

In this article, we will discuss the concept of Display characters in a string using C++ language

In this post, we are going to learn how to write a program to separate characters of a given string in C++ language

Code to separate characters of a string

Code to separate characters of a string using for loop

In this code, we are going to learn how to separate individual characters in the given string using for loop in C++ language

Program 1

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

int main()
{
    char str[100];//declare a char array
    int i;//declare a integer variable
cout<<"Please enter a string\n";
   cin>>str;//read input from the user

    for(i=0; str[i] != '\0';  i++){
        cout<<"The character at "<< "str["<<i<<"] index position: "<<str[i]<<"\n";

    }//display character of a string
    getch();
    return 0;
}

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

Please enter a string

The character at str[0] index position: C
The character at str[1] index position: o
The character at str[2] index position: d
The character at str[3] index position: e
The character at str[4] index position: M
The character at str[5] index position: e

Code to separate characters of a string using while loop

In this code, we are going to learn how to separate individual characters in the given string using while loop in C++ language

Program 1

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

int main()
{
    char str[100];//declare a char array
    int i;//declare a integer variable
cout<<"Please enter a string\n";
   cin>>str;//read input from the user
i=0;
    while(str[i] != '\0'){
        cout<<"The character at"<< "str["<<i<<"] index position: "<<str[i]<<"\n";
 i++;
    }//display character of a string
    getch();
    return 0;
}

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

The character at str[0] index position: M
The character at str[1] index position: y
The character at str[2] index position: W
The character at str[3] index position: e
The character at str[4] index position: b

Code to separate characters of a string using do-while loop

In this code, we are going to learn how to separate individual characters in the given string using do-while loop in C++ language

Program 1

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

int main()
{
    char str[100];//declare a char array
    int i;//declare a integer variable
cout<<"Please enter a string\n";
   cin>>str;//read input from the user
i=0;
   do{
        cout<<"The character at"<< "str["<<i<<"] index position: "<<str[i]<<"\n";
 i++;
    } while(str[i] != '\0');//display character of a string
    getch();
    return 0;
}

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