main() {int a=5,b=3,c=0; if (a=b+c) printf ("***\n"); else printf("$$$\n"); } 的运行结果为什么不是$$$啊
main() {int a=5,b=3,c=0; if (a=b+c) printf ("***\n"); else printf("$$$\n"); } 的运行结果
为什么不是$$$啊

main() {int a=5,b=3,c=0; if (a=b+c) printf ("***\n"); else printf("$$$\n"); } 的运行结果为什么不是$$$啊
if(a=b+c)中间是一个赋值表达式,把b+c的结果给a,然后对a进行判断,如果a不为0则打印***,否则打印$$$
