C++ : is what the meaning of #include<stdio.h>?
Post 302765997 by neutronscott on Monday 4th of February 2013 03:41:06 AM

Early in the compiling of a source, a preprocessor takes these # directives. #include basically puts all of stdio.h into the top of your code. the .h identifies it as a "header".
In C, before you use a function, the compiler must first know how it is suppose to be called.
For example, how many arguments and of what type? All this is in stdio.h, for the Standard I/O functions (things that print to the screen and such).
Usually, in C++ it's #include <iostream>, but we won't fault you for using C functions

string base_convert (string $number, int $frombase, int $tobase) DESCRIPTION
Returns a string containing $number represented in base $tobase. The base in which $number is given is specified in $frombase. Both $from- base and $tobase have to be between 2 and 36, inclusive. Digits in numbers with a base higher than 10 will be represented with the letters a-z, with a meaning 10, b meaning 11 and z meaning 35. Warning base_convert(3) may lose precision on large numbers due to properties related to the internal "double" or "float" type used. Please see the Floating point numbers section in the manual for more specific information and limitations. PARAMETERS
o $number - The number to convert o $frombase - The base $number is in o $tobase - The base to convert $number to RETURN VALUES

Example #1 base_convert(3) example <?php $hexadecimal = 'A37334'; echo base_convert($hexadecimal, 16, 2); ?> The above example will output: 101000110111001100110100 SEE ALSO
