c++： #include<bits/stdc++.h> using namespace std; int main(){ int n; scanf("%d",&n); for(int i=0;i<n;i++){ int a,b,c; scanf("%d+%d=%d",&a,&b,&c); if(a+b==c)printf("Right!\n"); else printf("Wrong!\n"); } return 0; }

#include<bits/stdc++.h> using namespace std; int main(){ int t; scanf("%d",&t); while(t--){ int a,b,c; scanf("%d+%d=%d",&a,&b,&c); if(a+b==c)printf("Right!\n"); else printf("Wrong!\n"); } return 0; }

众所周知，我们用cin 导入整数时，遇到不是整数的字符则停止输入。我们可以利用这个特性。

n=int(input()) for i in range(n): a=input().split('=') if eval(a[0])==eval(a[1]): print('Right!') else: print('Wrong!')

Python：n=int(input()) for i in range(n): a=input() z=a.index('+') m=a.index('=') b=az,a[z+1:m],a[m+1:] b=list(b) b=list(map(int,b)) if b[0]+b[1]==b[2]: print('Right!') else: print('Wrong!')
