Previous Question (not mine)

I have been reading a previous question, to try to figure out a problem. The problem regards leaving \n in the input buffer, thus i am having to press enter twice. One member replied stating using cin.ignore should sort this. I have tried in vain but it just doesnt want to play. I have tried cin.ignore (254,'\n''); etc etc (and a load of other things too.) If you could just scan my code and see why I need to press enter twice on each input I would be most grateful...When using cin.ignore(etc) I actually had to press enter THREE times to continue. Thanx.


const int PASSQUANT=10;
const int MAX_CHARS=7;
const int ATTEMPTS=3;

void main()

{

char Password [PASSQUANT][MAX_CHARS];
char User_Password[MAX_CHARS], Buffer[255];////255 max keyboard buffer
int Trys=0;
int ReturnVal;

for (int i=0;i<PASSQUANT;i++)
{
cout << "Please enter supervisor password for level "<<i+1<< "access ";
cin.getline(Buffer,255);///use the temp buffer to validate length


while (strlen(Buffer) !=(MAX_CHARS-1))//now checking password length
{
cout << "INCORRECT PASSWORD LENGTH ! ";
cout << "\nPlease enter supervisor password for level "<<i+1<< "access ";
cin.getline(Buffer,255); //obtain password again
}

strcpy (Password[i],Buffer); //put the validated password into real variable

} //end first for loop

clrscr();


etc etc

Program goes on etc, on debugger, all 10 passwords are shown niceley in the array with end of markers etc....just have to press enter twice!!




borland 5 proff

got me stuffed why u need to hit enter twice, I compiled using Microsoft Visual C++ and didn't have too. Well I made some changes to your code as shown below, found 1 logic prob with your code (or it could be that u are just forcing user to have exactly 7 char passwords, well here is what I got

Code:

#include <iostream.h>
#include <string.h>

const int PASSQUANT=1; 
const int MAX_CHARS=7; 
const int ATTEMPTS=3; 

int main() 

{ 

	char Password [PASSQUANT][MAX_CHARS]; 
	char User_Password[MAX_CHARS], Buffer[255];////255 max keyboard buffer 
	int Trys=0; 
	int ReturnVal; 

	for (int i=0;i<PASSQUANT;i++) 
	{ 
		cout << "Please enter supervisor password for level "<<i+1<< " access "; 
		cin.getline(Buffer,strlen(Buffer));///use the temp buffer to validate length 


		while (strlen(Buffer) > (MAX_CHARS-1))//now checking password length 
		{ 
			cout << "INCORRECT PASSWORD LENGTH ! "; 
			cout << "\nPlease enter supervisor password for level "<<i+1<< "access "; 
			cin.getline(Buffer,255); //obtain password again 
		} 

		strcpy (Password[i],Buffer); //put the validated password into real variable 

	} //end first for loop
	return 0;
}

thanks for that, but it is definate that I have to press enter twice....it takes the input and then drops o a new line-therefore i need to press enter again
