error handling 1

[oaquao]

I'am a student who has just started C++ and for practice I'am writing a simple game.
I have checked the archives and found nothing pertaining to this.
If a user enters improper data such as a number or nothing I want to correct it.

struct player
{
char firstName[ArSize];
int score;
};
player* plyr=new player[numPlyrs];
while (cin.get(plyr.firstName,ArSize))

Here is what I tried.
Any type of input is accepted.
When I use that test condition with an array it works so I would imagine it has something to do with the array of structures.

Any help would be appreciated.
Thank you.

Hi.

Take a look at the following function. I found the original
code a few years ago in a book from... David Vandevoorde I
think. I modified it a bit and use it to read strings
from stdin. As you can see each character is read
separately.

void ReadLn(std::string &s)
{
using namespace std;

const cnMax = 0x80; // max string length

int i=0, c;
char buffer[cnMax] = {0};

// skip leading whitespaces
while((c = cin.get()) && cin && isspace(c));

do // read line
buffer[i++] = char(c);
while((c = cin.get()) && cin && i != cnMax && c != '\n');

buffer= '\0'; // terminate char string
s.assign(buffer, i);

return;
}
