C中反转字符串的函数 [英] Function to reverse string in C

问题描述

我写了这个函数来反转 C 中的字符串，但是在字符串中切换字符时程序崩溃了.我不知道是什么原因造成的，因此我们将不胜感激.

I wrote this function to reverse a string in C, but when switching characters in the string the program crashes. I have no idea what's causing it, so any help would be appreciated.

void reverse(char s[])
{
    char c;
    int i;
    int j;

    for (i = 0, j = (strlen(s) - 1); i < j; i++, j--)
    {
        c = s[i];
        s[i] = s[j]; //An error occurs here
        s[j] = c;
    }

    printf("%s", s);
}

main()
{
    reverse("Example");
}

这应该可以解决它.

main()
{    
char array[] = "Example";
reverse(array); 
}

当你执行 reverse("Example") 时，这与

char *string = "Example";
reverse(string) //wont work
