C program to print Characters in a string

In this tutorial, we will discuss the concept of C Program to print Characters in a string

In this topic, we are going to learn how to display characters of a string in C programming language  using for, while and do-while loops.

Code to  display characters of a string in C

Code to display characters of a string using for loop

In this program, we are briefing how to display characters of a string using for loop in C language

Program 1

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

int main()
{
    char str[100];
    int i;
printf("Please enter a string!\n");
scanf("%s",str);
    printf("Characters of the given Strings!\n");
    for(i=0; str[i]!= '\0'; i++){
        printf("The charecters of str[%d] index= %c \n",i,str[i]);
    }
    getch();
    return 0;
}

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

Please enter a string!
Program
Characters of the given strings

The characters of str[0] index = P
The characters of str[1] index = r
The characters of str[2] index = o
The characters of str[3] index = g
The characters of str[4] index = r
The characters of str[5] index = a
The characters of str[6] index = m

Code to display Characters in a string using while loop

In this program, we are briefing how to display characters of a string using while loop in C language

Program 2

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

int main()
{
    char str[100];
    int i;
printf("Please enter a string!\n");
scanf("%s",str);
    printf("Characters of the given Strings!\n");
    i=0;
    while( str[i]!= '\0'){
        printf("The charecters of str[%d] index= %c \n",i,str[i]);
        i++;
    }
    getch();
    return 0;
}

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

Please enter a string!
Program
Characters of the given strings

The characters of str[0] index = C
The characters of str[1] index = o
The characters of str[2] index = d
The characters of str[3] index = i
The characters of str[4] index = n
The characters of str[5] index = g

 

 

Code to display Characters in a string using do-while loop

In this program, we are briefing how to display characters of a string using do-while loop in C language

Program 3

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

int main()
{
    char str[100];
    int i;
printf("Please enter a string!\n");
scanf("%s",str);
    printf("Characters of the given Strings!\n");
    i=0;
    do{
        printf("The charecters of str[%d] index= %c \n",i,str[i]);
        i++;
    }while( str[i]!= '\0');
    getch();
    return 0;
}

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

Please enter a string!
print
Characters of the given strings

The characters of str[0] index = p
The characters of str[1] index = r
The characters of str[2] index = i
The characters of str[3] index = n
The characters of str[4] index = t
