C3321 无法解决 8 9段

#inclued <stdio.h> int main() { int a = 100, b = 10; int * pointer_1, * pointer_2; pointer_1 = &a; pointer_2 = &b; printf{ "a=%d,b=%d\n",a,b }; printf{ " * pointer_1=%d, *pointer_2=%d\n",*pointer_1,*pointer_2 }; return 0; }

printf是函数，用小括号，不能用大括号

printf("a=%d,b=%d\n",a,b);

printf("*pointer_1=%d,*pointer_2=%d\n",*pointer_1,*pointer_2);

无法解决 8 9段是什么意思？请把问题描述详细一点，谢谢！
