Useful Functions

◀ Operator Precedence▶ Random Number Generator Amazon In this section we will see some very basic but useful functions that a programmer may need at any point of writing a program. They include functions to product a random number, parse a string, convert between string and char array, tell time, pause for some time, convert from string to number and vice versa, tokenize a string, and output invisible characters.

As a note, some of the basic functions are already provided by standard libraries of C or C++. If you are uncertain what functions which library provides, simply do a search on the Internet.

For example, if you are not sure what functions math.h provides, google math.h in the search field.
