What is the purpose of including cmath?
No, acually my problem was that I wasn't thinking of size() or length() has member functions. I was using them like-
for (int i=0; i<size(sentence); i++)
//and
for (int j=0;...
I ment a string (the kind declared in string...not a character array). So I just guessed you could figure it out.
I am working on a challenge, and I need to find out how many characters are in a string. I have tried size() and length() but they both give me an error (undeclared identifier). But aren't those two...
I see what you are saying. Yep, that was a big problem I didn't see. Thanks. I am just not good at error checking and debuging.
Thank you so much for your help. I added some code to make every array element null before getting the phrase and producing the acronym, so that fixed the acronym problem you pointed out. And the cin...
Thanks alot, that fixed that problem. Next one is that if the character enters 40 characters the program crashes, I added a cin.ignore after I call getline to make sure no extra characters carry...
In my second version of my program that will help create a secure password for the user I am attempting to have it create an acronym from a phrase that the user types in. One problem that I am having...
I don't know if you know any VB or not. But this might be of help. ;)
What don't you use
using namespace std;
instead? But doing it your way would be better for learning since you will learn what namespace things belong to.
A nice reference is http://www.cppreference.com/
The specific page for strstr() is here, http://www.cppreference.com/com/stdstring_details.html#strstr
if (com[0] == 'm' || (com[1] == 'n' && com[2] == 'o'))
If com[0] equals 'm' or if com[1] equals 'n' and com[2] equals 'o,' then do what ever.
C++ introduced new and delete to replace malloc() and free(). So when using C++ just use new and delete, but in C these two are not avilable, so just use malloc() and free() when creating a C program.
You don't even need to seed, but it is always a good idea.
#include <iostream>
#include <cstdlib>
int main()
{
for (int i=0; i < 10; i++)
I am not sure what POSIX is, I guess it is just another standard? Anyways here are my plans for learning the C++ language-
[list=1]
Finish learning most of the language, basics, intermediate...
I will check out that book. You speak very highly of it. ;) I will also take a look at the other book mentioned.
Has anyone read this book? If so what did you think about it? Was it worth buying or is there a better book on the topic?
How could you, for example, set the inode of a file to a variable?
//something like this?
a = system("ls -i text.txt");
And also, since this is a Linux forum. How do you change your...
Usually goto statements can be replaced by some type of loop (for, while, do..while).
gustavosserra, try something like-
#include <iostream>
#include <string>
using namespace std;
int main()
{
string hello="hello";
Look into isdigit(). Or you could look into isalpha().
Enter BIOS at start-up and look through it to see if it supports passwords.
But creating the program for user verifacation qouldn't be hard but the only problem is that you would need to find a...
>Much easier then playing with vi.
Hahaha, I hate Emacs, I don't really care for vi either, thats why I choose vim!!!
CodeMonkey, I too am 14.
I think it would be a good thing, but not sure.
