Question about C

#include <stdio.h>
int main()
{
printf("This is output from my first program!\n");
return 0;
}
###
Then I run the sample program above it opens only for a eye blink and then quits. Does that happens because its not programed to wait or it should wait and so the problem is with my compiler?

run this
Code: Select all
#include <stdio.h>
int main()
{
printf("This is output from my first program!\n");
system("pause");
return 0;
}
what your program sais is
ok
get some headers
start the main bit
print something
return a good old exit code to windows
windows gets this, knows the application has finished, closes it
so no, nothing is wrong with your program... in a way

If you're running it in a visual compiler like Microsoft Visual C, try doing the "Run without debug." option. Thats what works in Visual C++.

perhaps try running it in from dos shell or clicking the program with mouse2 and setting "don't close on exit"?

Yes... Try using sleep or something similar (even a getc or scanf).

You can use getch(); instead of calling pause. Was that in stdio too?

Quite frankly start with C++ instead of C and read up on OOP, that's the way to go. Knowing C doesn't really help with C++ a lot. Also if you are interested in AI coding, most of the AIs are in C++.
Your typical hello world
Code: Select all
#inlcude <iostream.h>
void main(int argc, char* args[])
{
cout << "HOLLA WOLRD!" << endl;
cin.get();
}
The same with very basic OOP
Code: Select all
#inlcude <iostream.h>
class CHollaWorld {
CHollaWorld();
~CHollaWorld();
void Spam();
};
void CHollaWorld::Spam() {
cout << "HOLLA WOLRD!" << endl;
cin.get();
}
void main(int argc, char* args[])
{
CHollaWorld HelloWorld;
HelloWorld.Spam();
}
Haven't checked wether it runs or not nor if the syntax is correct though.

Thanks for the info people

Most minor AIs with AI devs learnign to code in C based languages (SAI by spectre, TAI by me) usually do it very badly because they use C style arrays for everything, and have no thoughts about proper object orientated modularity with usage of containers and other STL niceties.
This usually means the AI has a short lifespajn as it isnt flexible enough to expand and become more advanced and mature. AI needs modularity in the extremes. They need to be highly extendable in their design.

C++ contains a lot more "magic" stuff though, such as the << operators that look like inconsistent syntax to newbies I think.
And a beginner making an AI in C++ will make it just as inflexible as in C (although slightly fewer memory bugs maybe..), so I doubt thats a real difference.

Well learning C doesn't help much with C++ from my own experience in the end. That was my concern.

I believe it makes the whole learning process quicker with regards to AIs. I know my progress started to quicken once I stopped using old C stuff and moved to STL stuff and other marvels of C++.

That program runs in a console. Windows opens a console for that program and, when finished, closes it.
If you run that program from a console open by yourself it will only be closed when you order it to.

Ho, and C and C++ suck tremendously as languages (and even as learning platforms), now that i have seen the light after so many years strugling with all the shit that comes with the ill-fated mix that is C/C++.

Wouldnt it be nice if someone invented some program capable of making language conversions...

I can't believe its not obvious that <my language(s) of choice> are clearly superior! For example, <my language(s) of choice> has the following:
1) Ease of use
2) <More stuff>
3) Plus, there's <some random number of applications> well-known applications coded in it!
<Conspicuous ignoring/shrugging off of bad points concerning language>
Clearly, it is superior!
