利用数组进行删除一个整数

#include <iostream>
#include <iterator>
#include <algorithm>
using namespace std;

int main( void )
{
    int a[10], x;

    // 输入
    using Type = remove_extent_t<decltype(a)>;
    copy_n( istream_iterator<Type>(cin), size(a), begin(a) );
    cin >> x;

    // 删除
    auto itor = find( begin(a), end(a), x );
    if( itor != end(a) )
        itor = remove( next(itor), end(a), x );

    // 输出
    copy( begin(a),itor, ostream_iterator<Type>(cout," ") );
}
