Question

“{”: 缺少函数标题(是否是老式的形式表?)

#include "stdafx.h"
#include <iostream>
int Subtract (int first, int second);
{
std::cout << "Subtract() received " << first << "and" << second << "\n";
return (first - second);
}

int main()
{
using std::cout;
using std::cin;

cout << "I'm in main()!\n";
int a, b, c;
cout << "Enter two numbers:";
cin >> a;
cin >> b;
cout << "\nCalling Subtract()\n";
c=Subtract(a,b);
cout << "\nBack in main().\n";
cout << "c was set to " << c;
cout << "\nExiting...\n\n";
return 0;
}

第一个大括号老显示红色，不知道是什么原因，错在什么地方，请高手帮忙，用的是C++2010学习版

Answer 1

int Subtract (int first, int second) //最后的分号是多余的，必须去掉
