C++新手求助：这里用strcpy（s,t）为什么报错？

Question

#include
using namespace std;

class STR {

private:

char* s; int m, n;

public:

STR(char* t) {
    s = new char[strlen(t) + 1];
    strcpy(s, t);
    m = 0; n = 0;
}
void fun() {
    char* p = s;
        while (*p)

        {
            if (*p ==' ' || *p == ',' || *p == '.')m++;
            if (*p == '.')n++;
            p++;
        }

}
void print() {
    cout << "字符串：" << s << endl;
    cout << "句子数：" << n << endl;
    cout << "单词数：" << m << endl;
}
~STR() { delete[]s; }

};

void main()

{
char a[200] = "i am a student. i am twenty. i come from china.";

STR text(a);
text.fun();
text.print();

}

用的是vc++吧。vc++默认禁止你使用strcpy(也包括scanf gets等)
你有两个办法，一个参考：

设置编译器，允许strcpy
另一个办法是使用
strcpy_s代替
strcpy_s(s,strlen(t) + 1,t);
