Reverse a String In-Place

Code

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

void reverse_string(char *str) {
    // Your logic here
    char *left=str,*right=str+strlen(str)-1;
    while(left<right){
        char temp;
        if((*left)!=(*right)){
            temp = *left;
            *left = *right;
            *right = temp;
        }
        left++;
        right--;
    }

}

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;
}
