    A couple questions

    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";
    }

    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.";
        }
    }
