#include <iostream.h>
void main()
{
int a=3,b=5,ab,bb;
ab=a%3*5(int)(5/7)+b;
bb=(float)(a+b)/2;
cout<<"1题答案"<<ab<<endl;
cout<<"2题答案"<<bb;
}
总提示有一个错误.

#include <iostream.h>
void main()
{
int a=3,b=5,ab;
float bb;
// ab=a%3*5(int)(5/7)+b; ////这里
///////
ab=a % 3 * 5 /*这里要加一个运算符啊,如 + */ + (int)(5/7) + b;
bb=(float)(a+b)/2; // bb改为float型，不过一般都用double
cout<<"1题答案"<<ab<<endl;
cout<<"2题答案"<<bb;
}

ab=a%3*5(int)(5/7)+b;
5的后面少一个运算符。
