Reverse a String In-Place

Code

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

void reverse_string(char *str) {
    // Your logic here
    int strlength = strlen(str)-1;
    for(int i= 0 ; i<strlen(str)/2;i++){
        char temp = str[i];
        str[i] = str[strlength];
        str[strlength--] = temp;
    }
    return;
}

int main() {
    char str[101];
    fgets(str, sizeof(str), stdin);

    // Remove newline
    int i = 0;
    while (str[i] != '\0') {
        if (str[i] == '\n') {
            str[i] = '\0';
            break;
        }
        i++;
    }

    reverse_string(str);
    printf("%s", str);
    return 0;
}
