#include  
#include  

Int main () 
{
Char user [20]={0}; 
Char pass [20]={0}; 

Printf (" please enter the user name: \ n "); 
The scanf (" % s ", the user); 

If ((STRCMP (user, "a")==0) | | (STRCMP (user, "b")==0) | | (STRCMP (user, "c")==0)) 
{
Printf (" please enter the password: \ n "); 
The scanf (" % s ", pass); 
If ((STRCMP (user, "a")==0) & amp; & (STRCMP (pass, "111")==0) | | 
(STRCMP (user, "b")==0) & amp; & (STRCMP (pass, "222")==0) | | 
(STRCMP (user, "c")==0) & amp; & (STRCMP (pass, "333")==0)) 
Printf (" welcome! \n"); 
The else 
Printf (" password error! \n"); 

}
