RT，教以下代码能过：
#include <iostream>//注意这里！！！！
using namespace std;
int a , b;
main(){
scanf("%d%d" , &a , &b);
printf("%d" , a + b);
}尤其注意头文件

注：C++20过了，C++98 CE

@HeCao2008
iostream和
scanf、printf能共存？

@xuyiluo2 盲猜是因为 20 比 98 新，可能做了一些改动。

@xuyiluo2 凭什么不能，另外可能在低版本 iostream不包含scanf，你不CE谁CE？

@xuyiluo2 什么鬼，我试试
by HeCao2008 @ 2022-12-21 16:57:55
@xuyiluo2 那么就代表20能兼容，98不能兼容呗，而且似乎可以bdfs（

@HeCao2008 一直能兼容啊
