check if a string is a palindrome in C

int isPalindrome(char str[]) 
{ 
    // Start from leftmost and rightmost corners of str 
    int l = 0; 
    int h = strlen(str) - 1; 
  
    // Keep comparing characters while they are same 
    while (h > l) 
    { 
        if (str[l++] != str[h--]) 
            return 0; 
    } 
    return 1; 
} 

This code checks if a given string is a palindrome or not. It takes the string as a parameter and returns 0 or 1 depending on the result. The first step is to define two variables, l for the leftmost corner of the string and h for the rightmost corner. The loop then runs which keeps comparing the characters of the string starting from the leftmost corner until the rightmost corner. If a mismatched character is found, it returns 0 which implies the string is not a palindrome. If no mismatched characters are found, it returns 1 meaning the string is a palindrome.
