Syntax For Defining An Inline Function In C++: inline data_type function_name(Parameters) {//actual function code} Here, inline: This keyword suggests to the compiler to insert the function's code directly where it's called. data_type: It specifies the return type of the function. function...

The syntax of an abstract class in C++ is as follows: class className {public:virtual return_type fun_name()=0;}; An abstract class can also be defined using the keyword ‘struct’. The difference is that struct members are public by default, whereas class members are private. The synta...
In the above code, point_func is a pointer that points to a function having two integer variables as arguments and int as the return type. typedef With Function Pointer The syntax looks somehow odd for typedef with a function pointer. You only need to put the typedef keyword at the start...
Thedirect-declarator(in thedeclaratorsyntax) specifies the name of the function being defined and the identifiers of its parameters. If thedirect-declaratorincludes aparameter-type-list, the list specifies the types of all the parameters. Such a declarator also serves as a function prototype for la...
If this isn't done, the proper syntax for the function declaration may be deduced from the declarator syntax for the function pointer by replacing the identifier (fpin the above example) with the functions name and argument list, as follows: ...
