Compiler errors: no comprendo
This boot-up password program compiles and runs with MSVC++. Now I want to compile it using GCC (DJGPP), and I get this error which I don't understand:
password.cpp: In function 'int main(...)'
password.cpp: 48: implicit declaration of function 'int strcmpi(...)'
What? Implicit? Understood but not stated? Does anyone know what is meant by this error? I belive the same error applies to my every other call of 'strcmpi()', if I were to remove the one mentioned.
Here is the main function:
Code:
int main()
{
char* password = new char[50];
char* response = new char[50];
bool ChangePassword = false;
bool bypass = false;
ifstream ReadPasswordFile;
ofstream WritePasswordFile;
ReadPasswordFile.open("c:\\password.psw");
system("cls");
if(ReadPasswordFile.fail())
{
cout << "Could not open password file: using default password" << endl;
strcpy(password,"ishboo");
}
else
{
ReadPasswordFile.getline(password,50);
if(password[0] == (char)141)
{
ReadPasswordFile.close();
return 0;
}
}
ReadPasswordFile.close();
while(1)
{
cout << "What's the password?" << endl;
//PASSWORD ENTRY PUMP (DISPLAYS ONLY '*')
PasswordPump(response);
//END PASSWORD ENTRY PUMP (DISPLAYS ONLY '*')
if(!strcmpi(response,password))
{
cout << "Thanks youz!";
for(int x = 12; x < strlen(response); x++)
putch(32);//space
putch('\n');
if(ChangePassword)
{
while(1)
{
cout << "\nInput new password: ";
PasswordPump(password);
cout << endl;
cout << "Plese retype: ";
PasswordPump(response);
cout << endl;
if(!strcmpi(password,response))
{
WritePasswordFile.open("c:\\password.psw");
if(!WritePasswordFile.fail())//if it succeeded
WritePasswordFile << password;
else
{
cout << "Could not open \"c:\\password.psw\"." << endl;
break;
}
cout << "Password change complete!" << endl;
WritePasswordFile.close();
break;
}
else
{
cout << "Those two are inconsistant!" << endl;
}
}
}
if(bypass)
{
WritePasswordFile.open("c:\\password.psw");
if(!WritePasswordFile.fail())//if it succeeded
WritePasswordFile << (char)141;
else
{
cout << "Could not open \"c:\\password.psw\"." << endl;
break;
}
cout << "Password bypassed!" << endl;
WritePasswordFile.close();
}
break;
}
else if(!strcmpi(response,"change password") || !strcmpi(response,"changepassword"))
{
ChangePassword = true;
wrong(response);
}
else if(!strcmpi(response,"bypass"))
{
bypass = true;
wrong(response);
}
else
wrong(response);
}
//system("cls");
return 0;
}
