C Tutorial - C syntax - [ID:545] (5/8)

in series: C programming tutorial.

video tutorial by gasto, added 03/08

Series ID: 138 Video ID: 545

In this occasion, we build a simple program that prints 3 numbers, with the help of the printf() function defined in <stdio.h> . The concepts of C's storage class specifiers are explained (probably the most confusing aspect of the C syntax). The difference between definition and declaration is explained and the concept of 'extern'(storage class specifier); 'char', 'short', 'int'(types) is clarified. Block scope is demystified, and the storage classes characteristics(duration, scope and linkage) are explained by examples.

Visit the C Console Programming video series for updates on C programming from me.

// Csyntax.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"

extern short shortnum;
extern void doSomething(void);

int _tmain(int argc, _TCHAR* argv[])
{
	//extern short shortnum;
	char letter = 't';
	char * string = "hello everyone";
	float floatnum = 4.45462;
	int num = 3;
	short assignment = shortnum;
	short shortnum = 2;
	doSomething();
	doSomething();

	if (num <= 2) {shortnum = 4;}
	printf("%d \n", shortnum);
	
	
	getchar();
	return 0;
}

void doSomething(void){
	//static variable = 1;
	printf("%d \n", shortnum /*,variable*/);
	//variable++;
}

Don't worry. Although receiving some extra money wouldn't hurt, I'm doing it to help back a community that has already served me.

Educating the Open-source Community With Showmedo

Although as important as the software it supports, education and documentation are relatively neglected in the Open-source world. Coders love to code, and explaining how best to use or improve the software tends to be deferred or even sidelined.

At Showmedo we believe the community can play a vital role here and also say thanks for the tools and software that make our lives easier. If you have a piece of software you love or a programming langugage you are enthusiastic about, why not make a screencast showing others how to use it? All the stuff you wish you'd been told, the tips, tricks, insights that would have saved you time and frustration.

Screencasting is easier than you think, and we're happy to help you. You can emailus for advice or just use some of the how-to screencasts on the site. This screencasting learning-pathis a good place to start.

Kudos and Thanks for gasto
