New To C++ Programming

**suku_chen** · 07-28-2002

Hi all, may I ask if, I want to write a program that is like a software, which others can download . Can I use C++ Programming to do that? Lets say I cannot, but can I use C++ Programming to point to a software, that can help me to do what I want, for my convenience?
THanks...

rephrase your question...

c++ is a programming language
software is the collective term for programs and data

let's say you write a program using the c++ language. it looks like this:

Code:

#include <stdio.h>
int main() {
  printf("Hello, world!\n");
  return 0;
}

then you obtain a compiler, which is a program which converts c++ source code to a program. it gets a bit more complicated, but that should suffice for now.

so to answer your question: yes, you can use c++ to write a program people can download.

You can do just about anything with C++. I'm sure if you learn the language well enough you will solve most of your programming problems.

The code that ygf posted is C code and not c++ code. It will compile in a C++ compiler and can be used in your C++ programs but in reality that would be a C program.

on your queston, C++ can be used to program nearly anything. The only thing it is device drivers, OSes, low leval programs, and were speed is important.

I sort of understand some of what you all have said. But this part is a bit complicated.
Well, I want to design a program, that people can use to save numbers by clicking on buttons, etc, such as what fields do they want, etc, and then save as a format that it will follow the program, such as doc for Words, cfm for Coldfusion, etc. Is it possible to do that? Do I need to include any databases or they just save itself when the user saves it?

**black** · 07-29-2002

a bit confused.

if what you need is some kind of language, C++ would do.
if you ask for some software which C++ could run, there are many ones such as DevC++, BCB, VC and so forth.

Good luck~

Let me simplify my question.

(1) What I want to know if I can create a software such that, when the user save the page, it will be saved as .mim, etc.

(2) mim is my very own saving extension. Its like when you save a picture, it's in jpg, or gif, etc.

(3) If it is not possible, is it possible to create a program that user can save, and reuse what he've made the previous attempt and save it again?

>> printf("Hello, world!\n");

Thats C not C++. The C++ eqivelant would be

Code:

cout << "Hello, world!\n"; // in <iostream.h>

Okay everyone, I think suku_chen knows that the example posted is c not c++. To answer your question yes you can save things as a .mim file. Now I'm going to ask you a question are you trying to make a program in which you can save a .mim file that would be a copy of what is on the screen (or on a given window)? If so, yes you can do that too. If you want to save to a .mim file you can do this:

Code:

//C way
FILE *mim_file = fopen("save.mim", "w");
//C++ way
ofstream mim_file("save.mim")

yuo ashouldnt really just ask people to write you programs tha takes the fun out of it. try LEARNING c++ first. cprogramming.com theres like 18 i think

>Thats C not C++.
Yes it is, C++ supports printf.

>cout << "Hello, world!\n"; // in <iostream.h>
iostream.h is the old header, the new header which should be used is <iostream> and you must take namespaces into account:

Code:

#include <iostream>
.
.
std::cout<<"Hello, world!\n";
// or
std::cout<<"Hello, world!"<<std::endl;

or just put
using namespace std;

at the top

Is there any good compiler around? and its free of charge? Thanks
