数组类型'int [8]'是不可分配的

Question

在此问题上停留了很长时间并且无法找到解决方案，不断出现错误消息数组类型'int [8]'是不可分配的。 也告诉我，数组条目“表达式必须是可修改的左值”，我试图多次查找并且似乎什么也没想到，任何帮助都是有用的:)使用命名空间std;

const int MAXACCOUNTS = 8;


int main()

{
cout << "Welcome" << endl;
int counter = 0;
int counter1 = 0;
int interest_counter = 0;

struct Account
{
    int AccountNumber[MAXACCOUNTS] ;
    double Balance[MAXACCOUNTS];
    int DaySinceDebited[MAXACCOUNTS];
};

Account entries[MAXACCOUNTS];

while (counter1 != MAXACCOUNTS)
{
    if (counter1 = 0)
    {
        entries[counter1].AccountNumber = 1001;
        entries[counter1].Balance = 4254.40;
        entries[counter1].DaySinceDebited = 20;
        counter += 1;
    }
    else if (counter1 = 1)
    {
        entries[counter1].AccountNumber = 7940;
        entries[counter1].Balance = 27006.25;
        entries[counter1].DaySinceDebited = 35;
        counter += 1;
    }
    else if (counter1 = 2)
    {

}

cout << "Acct No   Balance   Interest Paid" << endl; 

while (counter != MAXACCOUNTS)

您已经将AccountNumber ， Balance和DaySinceDebited为数组，但是尝试为它们分配单独的值。 您将它们视为不是数组，因为从逻辑上讲，将它们作为数组没有意义。 请记住，您有多个帐户（一组帐户），但是每个帐户只有一个AccountNumber，Balance等。不要将它们制成数组。 而是将它们声明为：

int AccountNumber;
double Balance;
int DaySinceDebited;

另外，在每个if ，都需要使用==进行比较。 截至目前，您的陈述如下：

else if (counter1 = 1) {
                 ^^^

这会将值1分配给counter1 ，然后检查其值是否为true。 由于所有整数（0除外）在C ++中均评估为true，因此将始终运行该整数。 将其更改为：

else if (counter == 1) {
