Thread: help with my program

Hey, I'm making my own encryption code and I will post the part where I need help with::


This may be unproper but this is like the pre pre beta stage lol

cout<<"Enter something you want to encrypt: "<<endl;
cin.get(user, 100);
cin.ignore(102, '\n');
clrscr();

do
{
user[x]=1;
l++; x++;
}

while(x!=26);

My question is I need to make the while statement know how many characters the user enters but I don't know how, is there a way to count how many characters the user types...This program is pretty crappy right now...i plan on making it letting u encrypt files and crap...but anyway if someone knows.... THanks


Also if you have any suggestions that would be great

use strings in the std string header.

This -

char arr[256];
cout << "chars: " << cin.get(arr,256).gcount();

or you could use strlen() on the string, or as golfinguy4 has stated use std::string which has a member function which will return the length.

What would go in the while part of the do? I am pretty new...Im only in computer programmin II in my school

I didn't realise this was a school assignment, sorry. In that case we need to change -

>My question is I need to make the while statement know how many characters the user enters

to

>The question I've been given is I need to make the while statement know how many characters the user enters

In which case something like this would work -

char arr[256];
cin.get(arr,256);
int j=0;
while(arr[j])
j++;

'j' will contain the amount of characters entered minus the '\n'
