c++编译小疑点 求解答

c++编译小问题 求解答
#include<iostream>
using namespace std;
#include<string.h>
int main()
{
char password[20];
strcpy(password,"123456");
cout<<"please inter:"<<endl;
char a[20];
cin>>a;
if(a==password)
cout<<"yes!";
if(a!=password)
cout<<"no!";
}
如何才能把123456赋值给password?

[解决办法]

C/C++ code

#include<iostream>using namespace std;#include<string.h>int main(){    char password[20];    strcpy(password,"123456");    cout<<"please inter:"<<endl;    char a[20];    cin>>a;    if(strcmp(password,a)==0)        cout<<"yes!";    else        cout<<"no!";}

记住字符串比较不是像单个字符一样直接比较
用：
strcmp, wcscmp, _mbscmp
Compare strings.

int strcmp( const char *string1, const char *string2 );

int wcscmp( const wchar_t *string1, const wchar_t *string2 );

int _mbscmp(const unsigned char *string1, const unsigned char *string2 );

C/C++ code
#include<iostream>using namespace std;#include<string.h>int main(){    char password[20];    strcpy(password,"123456");    cout<<"please inter:"<<endl;    char a[20];    cin>>a;    if(!strcmp( a, password))        cout<<"yes!";    else        cout<<"no!";    return 0;}
