帮我看下我的代码的错误

[piaomiao163]

我想实现这样的功能:


我的代码:

#include <iostream>
#include <vector>
using namespace std;

int main()
{
    cout << "Please Enter Some IntNumbers" << endl;
	vector<int> vector_int;
	int i, j(0) ;
	while( cin >> i )
	{
		vector_int.push_back( i );
		++ j ;
	}
	if ( isdigit( j % 2 == 0 ) )
	{
	    cout << "The number of Intnumbers is not enough" << endl;
	}
	else
	{
	    for ( int i = 0; i < j; i+=2 )
			cout << vector_int[ i ] + vector_int[ i+1 ] << endl;
	}
	system("pause");
}

运行的时候出现错误～～

isdigit( j % 2 == 0 )的用法肯定不对
使用
if ( j % 2 != 0 )
{
cout << "The number of Intnumbers is not enough" << endl;
}

输入数据时用ctrl+z作为结束条件。

//这样试一下吧。
