When using functions that are in the standard library, I find that to use them I sometimes have to include the appropriote header, and sometimes I do not. e.g the strlen() function: I can use it without including the header it needs....
can anyone tell me why?
p.s. Just thought it would be fun to tell yaŽll, IŽm in Mexico at an internet cafe, the cost is 10 pesos (aprx. $1 USD) per hour...not bad... and since IŽm not near a compiler, IŽm not sure for certain whether the strlen() will work without a header. sorry if it doesnŽt.
