我正在尝试使用简单的堆栈推送和弹出来反转字符串。但是，我收到一些我无法理解的错误

阿育王

我的代码：

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


void Reverse_string(char *C, int n)
{
    stack<char> S;
    for(int i =0; i < n ; i++)
    {
        S.push(C[i]);
    }

    for(int i = 0; i< n; i++)
    {
        C[i] = S.top();  //overwite the char at index i
        S.pop();
    }

}
int main()
{
    char C[51]= "Hello WOrld";

    Reverse_string(C,11);
    printf("Output = %s", C);
}

错误：

您似乎在链接到C ++运行时库时遇到问题。出于某种原因，编译器可能正在尝试以C模式进行编译。我假设您使用Linux作为操作系统。

尝试命令g++ program.cpp -o program。如果无法编译，请告诉我错误是什么。
