if(sale>100)?{

if-else對(duì)應(yīng)好，17行少了個(gè)大括號(hào)

#include?<stdio.h>
int?main()?
{
????int?sale=120;?//銷售業(yè)績(jī)?yōu)?20萬(wàn)
????int?year=1;?//剛剛進(jìn)入公司1年
????//完善代碼
????if(sale>100)
????{
????????if(year>=2)
????????{
????????printf("%s\n","恭喜獲得優(yōu)秀員工");
????????}
????????else
????????{
????????????printf("%s\n","很遺憾，期望你再接再厲");
????????}
????}
????else
????{
????????printf("%s\n","很遺憾，期望你再接再厲");
????}
????return?0;
}

這個(gè)是正確代碼，另外在左側(cè)也有源碼提示
