[SOLVED] C question

[blackcell]

Hey I don't quite grasp the idea of using %d as in:

 

scanf ( "%d", &units ); 

or in

printf( "%d Units", unit);

 

Also, does anybody have any good recommendations for sites like this covering C?

Its exactly the same as in php. Take a look at sprintf.

 

Also, does anybody have any good recommendations for sites like this covering C?

 

You might try here.

Don't think I have ever used it in PHP and now my C college class brought it up and it threw me for a loop.  Thanks for the info and site!

Do ref :  acm.uiuc.edu/webmonkeys/book/c_guide/  for more on C programming it's very useful source for all about C language.

in the case of

 

scanf("%d", &units);

 

%d is saying to expect an integer.

 

others are %f for float, double and %c for char but there are more

 

 

in the case of

printf("%d Units", unit);

 

thats to say where you want the integer to be displayed

 

 

take your phone number for example

 

to print (XXX) XXX-XXXX, you can do that in one line of code:

printf("(%d) %d-%d", areaCode, exchange, phNum);
