C++ Built-In Function: The functions that have already been defined and are part of the language and can be used in any program are called built-in functions. Accessing Built-in Functions: The built-in functions are accessed through header files. Each built-in function is defined in its related header file. If a built-in function is to he used in a program, its header tiles must be included in... 

An Indifference Map: A graph showing a whole set of indifference curves is called an indifference map. In the given figure three indifference curves IC1, IC2 and IC3 have been shown. The various combination of goods of wheat and rice lying on IC1 yield the same level of satisfaction to the consumer. The combination of goods lying on higher indifference curve IC2 contain more of both the goods wheat... 

The Construction of Indifference Curves: The consumer’s preferences can be shown in a diagram with an indifferences curve. The indifferences curve shows nothing about the absolute amounts of satisfaction obtained. It merely indicates a set of consumption bundles that the consumer views as being equally satisfactory. In the given figure, we measure the quantity of wheat along X-axis (in kilograms)... 

C++ Function Templates: In functions overloading, more than one function with same name are declared and defined. This makes the program more complex and lengthy. To overcome this problem, function template is used. In a function template, a single type less function is defined such that arguments of any standard data type can be passed to the function. The general syntax of a function template is: template... 

C++ Functions Overloading: Declaring more than one function with the same name hut with different set of arguments and return data types is called functions overloading.             For example, three functions with same name “sum” and having different parameters are declared as:   int sum (int, int); int sum (int, int, int); double sum (double, double, double);                ... 

Inline Functions:             The inline functions are a special function used for small functions. It is a user-defined function hut in it the function prototype is omitted. The keyword “inline” is used in the decelerator on the function definition. The “inline” function is defined before the main function. When a compiler compiles the source code, it generates a special code at... 

C++ Command Line Arguments:             When a program in C++ is compiled an executable file is created. This executable file can he used to execute the program directly from the DOS prompt. The arguments can also he passed to the program from the DOS prompt during execution of the program. The arguments that are passed to a function at the DOS prompt are called command line arguments.            ... 

Default Arguments:             The arguments in which data is initialized during the function declaration arc called default arguments. If the values of the arguments are specified in the function declaration then the arguments of the function in the function call can be omitted. If the arguments are omitted in function call then the default values are automatically passed to the function... 

Local and Global Functions:             The functions that are declared inside the main function or inside any other function are called local functions. They can he called only in that function in which they are declared. The functions that are declared outside the main functions are called global functions. They can he called by any function. The function prototypes defined in the header... 

Static Variables:             Static variables arc special variables that are declared inside a function by using the keyword “static”. Like local variable, these can only be accessed in the function in which they are declared hut they remain in existence for the lifetime of the program. Another difference between local variables and static local variables is that the initialization...
