A common gap usually appears in a trading range or congestion area, and reinforces the apparent lack of interest in the stock at that time. Many times this is further exacerbated by low trading volume. Being aware of these types of gaps is good, but doubtful that they will produce a trading opportunities.
Conversion functions (C++ only) You can define a member function of a class, called a conversion function, that converts from the type of its class to another specified type.
The C standard library provides numerous built-in functions that your program can call. For example, strcat() to concatenate two strings, memcpy() to copy one memory location to another location, and many more functions. A function can also be referred as a method or a sub-routine or a procedure, etc.
