Coding noob - Hello World?

[spadez]

Im so super noobie at programming -

#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])

{
	const char text = Hello World;
	char text[15];
	printf("%c", text);
	return 0;
}

What im trying to do in the simple bit of code is define a vairable at the top, in this case, I want the variable text to be "Hello". I then want to print this variable below.

What am i doing wrong?

int main(void)
{
   const char* text = "Hello world";
   printf("%s\n",text);
   return 0;
}

look at the red parts

A bunch of things. You need to include stdio.h for printf:

#include <stdio.h>

You must quote string literals:

"Hello World"

You try to assign a string to a single char:

const char text =

then you redefine "text" as something else

char text[15];

And your printf template should contain %s, not %c.

[spadez]

#include <stdio.h>
#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])

{
	const char* text ="Hello World";
	printf("%s", text);
	return 0;
}

Thank you for the help. Can you explain what the * is for next to char? This is my code above. It compiles and works, is it now properly coded?

Edit: Since there are no arguments - can i change int main to (void) instead of (int argc, _TCHAR* argv[])

It means it's a pointer

char in C could store only 1 character, to build a string you need an array of characters
"Hello world" is string literal - it means array of characters stored somewhere by the compiler, and you have only read access to it. Your text variable is a pointer to this string.
you can look at the tutorial section on this site - it has a lesson about strings as well

yes - read FAQ CProgramming.com FAQ > main() / void main() / int main() / int main(void) / int main(int argc, char *argv[])
