Question

新手求指导，C++改错，错因“cannot convert parameter 1 from 'char [2]' to 'char'”

#include <iostream>
using namespace std;
void hanoi(char x,char y,char z,int n)
{
if (n==1)
cout <<"1:"<<x<<"→"<<y<<endl;
else
{
hanoi(x,z,y,n-1);
cout <<n<<":"<<x<<"→"<<y<<endl;
hanoi(z,y,x,n-1);
}
}
void main()
{
hanoi("A","B","C",8);
}

Answer 1

char是一个字符，应该用单引号，双引号是字符串

hanoi('A', 'B', 'C', 8);

Answer 2

hanoi(‘A’,‘B’,‘C’,8);
