char *ch(char *str1,char *str2);
请问这句是什么含义，第一次看到。

#include <stdio.h>

char *cp(char *str1, char *str2);

int main(int argc, char *argv[])
{
    char str1[50] = "I am glad to meet you!";
    char str2[50] = "Welcome to study C!";
    printf("%s\n", cp(str1, str2));
    return 0;
}

char *cp(char *str1, char *str2)
{
    char *ret = str2;
    while (char p = *str1++) {
        *str2++ = p;
    }
    *str2 = NULL;
    return ret;
}
