C Program to Print Reverse of a String without strrev() function

#include <stdio.h>
#include <string.h>

int main()
{
    int i,j,len=0;
    char str[50],revstr[50];
    printf("\n Enter a String to Reverse : " );
    // Use fgets to read input, with a maximum size of 50 characters
    fgets(str, sizeof(str), stdin);
    // Remove the newline character from the end of the string
    str[strcspn(str, "\r\n")] = 0; 
    // Count the length of the string
    for(i=0; str[i]!='\0'; i++)
    {
        len++;
    }

    j=0;
    // Reverse the string by copying each character from the original string to the new string in reverse order
    for(i=len-1; i>=0; i--)
    {
        revstr[j++]=str[i];
    }
    printf("\n Reverse of the Given String is: %s",revstr);
    return 0;
