A couple questions

**Flakster** · 08-08-2005

I have a couple questions. They should be pretty simple to answer, but for a beginner these problems are daunting.

I have some text in cout that has \'s then words, so the compiler gives me these errors...

[Warning] unknown escape sequence '\D'

Is there a way to get around that? It compiles fine, but I don't see the the \'s in my text when the program runs.

Question 2...

I'm just playing around at the moment, trying to get familier with C++. I was making a little console program to scare my friends, I want to make a stupid little program that makes it look like I am deleting all the files on my computer. Something simple.

Such as I will just type delete.exe or something like that. How can I set it up so that there is a brief pause between that and the next line of text which would be something like "Files Deleted Successfully".

Something that would make it look like...

Delete.exe
Deleting...
*Then a few second pause*
Files Deleted.

Sorry if that is a long explanation for something so simple, but thanks in advance for any advice!

\ denotes an escape sequence. \n for a newline, \b for backspace, etc. So, when using a \ in your text, use \\. Same goes for " (\").

To pause for a little while, include windows.h and then use the function Sleep( Milliseconds );

To output a backslash, use "\\" for example:
cout<<"c:\\program files\\somefolder\\etc";

And check the faq on sleeping (although I think you should include <ctime> instead of <time.h>)

Edit: Beaten, although the faq does list other methods for sleeping

One more thing...

How come this won't work? Can the == operator only check numbers?

Code:

    if (input == file.exe)
       cout<<"Test";

I'm using the string variable so that input can hold a whole word. The error I get is...

`file' undeclared (first use this function)

If it's a string, you need to put it in quotes.

Code:

if( input == "file.exe" )
{
  std::cout << "Test";
}

Ah, thanks.

If it's a character array, you need to use strcmp():

Code:

#include <iostream>
#include <cstring>

using namespace std;

int main() {
    char one[80], two[80];

    cout << "\nEnter the first string: ";
    cin >> one;

    cout << "\nEnter the second string: ";
    cin >> two;

    if(strcmp(one, two) == 0) {
        cout << "\nThe strings are the same.";
    }
}
