Thread: Help- I'm new to this

The getchar() that is there now, is sucking in the newline character that was left from the scanf(). Do it again and you'll be coolio.

Can someone help me with DATA TYPES

int = %d
char = %s
float = %f
double = %?

or is double and %f?!?!?

and what's your technique to remembering them? Do you just know?

int = %d
char = %c
string = %s
float = %f
double = %lf
hex = %x or %X
pointer = %p

Technique to remember? The same technique you learn your new girlfriend's name - you just do it right.

for printf, %f is both float and double. For scanf, %lf for double, %f for float.

%s is for char[], %c for a single char.

And yes, I know those, and %u, %x, %o, %p, %zu, %lld, %ld, %hd. Any others, I'll look up when I need them.

You may want to look at this one:

and it's printf sibling, as it's got a more complete and accurate account of the standard variants.
