编译这段涉及对向量使用push_back函数的代码最终会出错.

for (int i=0; i<=n; i++)
{
    if(i==0)
    {
        Profit[i].push_back(0);
        Weight[i].push_back(0);
        Name[i].push_back("");
    }
    else
    {
        Profit[i].push_back(tosteal[i-1].getProfit());
        Weight[i].push_back(tosteal[i-1].getWeight());
        Name[i].push_back(tosteal[i-1].getName());
    }   
}

Weight和Profit是int数据类型的声明向量,Name是字符串数据类型的向量.tosteal是一个项目对象的数组.getProfit()和getWeight()返回一个int,getName()返回一个字符串.

这些是编译器给出的错误,有些是重复:
