C中的一个简单函数，用于反转指针所引用的字符串

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

void reverseString(char *str) {
    if (str == NULL) return;
    
    int length = strlen(str);
    for (int i = 0; i < length / 2; i++) {
        char temp = str[i];
        str[i] = str[length - i - 1];
        str[length - i - 1] = temp;
    }
}

int main() {
    char myString[] = "Hello, World!";
    printf("Original string: %s\n", myString);
    
    reverseString(myString);
    printf("Reversed string: %s\n", myString);
    
    return 0;
}
