[解决办法]
[code=C/C++]double Divide(double x,double y){if(y==0) {printf("除数不可以为0\n\n\n\n"); } else{return (x/y);}}
[解决办法]
result=Arith_compliment(tmp1,tmp2); int Arith_compliment(int x,int y)
double tmp1,tmp2; 类型不匹配。都是，自己查。
没别的错误，可以结了。
[解决办法]
[Quote=引用:]
C/C++ code
double Divide(double x,double y){if(y==0) {printf("除数不可以为0\n\n\n\n"); }else{return (x/y);}}int Arith_compliment(int x,int y){if(y==0){printf("除数不可以为0\n\n\n\n");}else{if(x <y){printf("除数不可以大于被除数\n\n\n\n");}elsereturn x%y;}}
[解决办法]
scanf_s用这就可以了
