Print characters in a string using C language

In this article, we will discuss the concept of Print 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 <stdio.h>
#include <stdlib.h>

int main()
{
    char str[100];//declare a char array
    int i;//declare a integer variable
    printf("Please enter a string\n");
    scanf("%s",str);//read input from the user
    for(i=0; str[i] != '\0'; i++){
        printf("The character at str[%d] index position = %c\n",i,str[i]);
    }//display character of a string
    getch();
    return 0;
}

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

Please enter a string
String

The character at str[0] index position = S
The character at str[1] index position = t
The character at str[2] index position = r
The character at str[3] index position = i
The character at str[4] index position = n
The character at str[5] index position = g

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 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char str[100];//declare a char array
    int i;//declare a integer variable
    printf("Please enter a string\n");
    scanf("%s",str);//read input from the user
    i=0;
    while(str[i] != '\0'){
        printf("The character at str[%d] index position = %c\n",i,str[i]);
        i++;
    }//display character of a string
    getch();
    return 0;
}

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

Please enter a string
coding

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 = i
The character at str[4] index position = n
The character at str[5] index position = g

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 3

#include <stdio.h>
#include <stdlib.h>

int main()
{
    char str[100];//declare a char array
    int i;//declare a integer variable
    printf("Please enter a string\n");
    scanf("%s",str);//read input from the user
    i=0;
    do{
        printf("The character at str[%d] index position = %c\n",i,str[i]);
        i++;
    }while(str[i] != '\0');//display character of a string
    getch();
    return 0;
}

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

Please enter a string
Program

The character at str[0] index position = P
The character at str[1] index position = r
The character at str[2] index position = o
The character at str[3] index position = g
The character at str[4] index position = r
The character at str[5] index position = a
The character at str[6] index position = m
