| | >Here's the doubt. You don't have a doubt, you have a question. To have a doubt means that you understand something, and subsequently disagree with it. A question, on the other hand, suggests incomplete understanding and a need or request for clarification. In some cases question can be used in … |

I always start with this: [code=cplusplus] #include <iostream> int main() { } [/code] >When it says "exponentially" then what formula should I use for the output? The description says to double approximately every 24 months. Using that as the baseline, you …  |
| | >in the underlined part, by greater value does it mean that A has greater value than B? strcmp compares each character in order and returns the result of the first two characters that don't match. It's equivalent to this implementation: [code=c] int jcmp ( const char *a, const char *b … |

 | >#define p printf This is an extremely bad idea. If your teacher taught it to you, slap him for me. >clrscr(); This is a bad idea. Not only is it anti-social (by removing the output of other programs when run in a shared console), it unnecessarily destroys the portability of … |

| | Post the code you've completed. We don't care how much you beg, no proof of effort results in no help. |
| | >Firstly, am I right? So far, yes. >I get Segmentation Fault. Did you allocate memory to the individual pointer or just the array? There are two steps here, first you allocate memory for the pointers in the dynamic array, then you allocate memory to each pointer to hold a node … |
| | You have three distinct problems. 1) You need to use square brackets instead of parentheses when dynamically allocating memory: [code=cplusplus] // Square brackets! name = new char[strlen ( foo ) + 1]; [/code] 2) You need to use the syntax for delete that matches the syntax for new: [code=cplusplus] base::~base() … |
| | Re: search strings2 You only perform the copying steps if the search string is found. Add a "not found" case where the line is copied as-is if the search string isn't located. |
 | In other words, part of the file is ASCII and the rest is binary data. >Can I do the above (ie. read with getline() and then read binary? Sure, but you may encounter problems with newline conversion. >How would I read 12 bits at a time (for a 12-bit color … |
| | That's a good start, but you aren't taking into account the rest of the data on the line. What you need to do is a string replacement, which involves copying everything before the search string to a buffer, append the replacement string, then everything after the search string. Depending on … |

| | Re: getch() problem >Now it somehow skips straight to 'else', missing out the 'if' and the 'else if'...... That's because getch doesn't perform text conversions. It's a straight detection of scan codes from the console. This means that on systems (such as Windows) where a newline is two values before being converted to … |
| | Re: small problem I'm not sure what you mean, but I'd guess that you don't know how to signal end-of-file from the command line, so the loop never ends. Hold down the ctrl key and press z (ctrl+z) if you're on Windows and d (ctrl+d) if you're on Unix or Linux. |
| | Here's something to play with as a template: [code=cplusplus] #include <ios> #include <iostream> #include <limits> #include <string> using namespace std; int main() { bool done = false; do { int value; cout<<"Enter a number: "; if ( !( cin>> value ) ) break; cout<<"You entered "<< value <<'\n'; // Clean … |

| | Re: List You know what [B]I[/B] need urgently? Hope for the future in the form of a beginner who actually does his or her own homework without begging for freebies. I actually don't mind giving freebies to people like that because they use the code wisely and for everyone's benefit.  |

Likewise, attention to detail in the graphics can improve gameplay by drawing the player in and offering more variety in how elements are displayed.

| | >Is C++ going to barf on that Possibly. It depends on whether A contains data members and if having multiple copies of the A subobject within a C object would cause problems in your code. Virtual inheritance was introduced to alleviate these kinds of problems. |
 | >I want the discussion to be related to my requirements, please. You didn't specify any requirements that can't be achieved with either language. Pick the one you're most comfortable with. |

| | Command line arguments are passed as parameters to main. The first parameter gives you the number of arguments (including the program name) and the second gives you an array of strings containing the actual arguments: [code=cplusplus] #include <iostream> int main ( int argc, char *argv[] ) { // The first … |
