C program to reverse a string without using strrev() function

Reversing a string is a very common question in basic programming interviews. In this article, we’ll learn how to reverse a string in C without using strrev() function. This C program takes a string as input from the user and then reverses it.

Program: C program to reverse a string without using strrev()

#include <stdio.h>
#include <string.h>
int main()
{
    char myString[50];
    int len, i;
    printf("Enter a string: ");
    fgets(myString, 50, stdin);
    len = strlen(myString);        //strlen() is a function of string.h, it returns the length of the string.
    for(i=len-1; i>=0; i--){
        printf("%c", myString[i]);  
    }
    printf("\n");
    return 0;
}

Output: Reverse string in C without using strrev()

Enter a string: Welcome to the world of computer programming.
