#include <stdio.h>
int main(void){
int i = 0;
char str1[] ="abcd";
char str2[] = "12,";
//while((str1[i] = str2[i++]) != ','){}
while((str1[i] = str2[i]) != ','){i++;}
printf("%s¥n",str1);
}
普通こう書くだろ．clangだと
1.c:6:24: warning: unsequenced modification and access to 'i' [-Wunsequenced]
6 | while((str1[i] = str2[i++]) != ','){}
| ~ ^

と怒られるわ．
