在VC++6.0上编译运行没问题，在LintCode上编译出了问题，是哪里有问题？

Question

//功能：输入两个整数，计算并输出它们的和
//语言：C++
#include<iostream>

using namespace std;

int main()
{
    int a,b,sum;
    cin >> a >> b;          //输入这两个数
    sum = a + b;
    cout << sum << endl;      //输出和
    return 0;
}

上面的代码在Visual C++6.0上运行没有任何问题，但在LintCode上面会出现如下错误警告，但我看不懂。

/code/Main.cpp: In function 'int main(int, char**)':
/code/Main.cpp:29:32: error: conflicting declaration of C function 'int main(int, char**)'
int main(int argc, char *argv[]) {

In file included from /code/Main.cpp:27:0:

Solution solution;

/code/Main.cpp:60:15: error: 'solution' was not declared in this scope

哪里有问题呢？

提示你main函数要有参数，写成int main(int argc, char *argv[])
