Macros are preprocessed, meaning that all the macros would be executed before the compilation stage. However, functions are not preprocessed but compiled. Example of Macro: #include<stdio.h> #define  A 10 int main() {      printf(“%d”,A);      return 0; }  OUTPUT=10; Example of Function: #include<stdio.h> int A() {     return 10; } int main() {     printf(“%d”, A());     return 0; } […]

The most important function of C is main() function. It is mostly defined with a return type of int and without parameters : int main() { /* … */ } We can also give command-line arguments in C . Command-line arguments are given after the name of the program in the command-line shell of Operating

In a program the most significant function is the main() function. It is defined with a return type of int and without arguments  int main()   {     /* … */   } Command-line arguments are typically the arguments given to the main function.It includes two arguments the first argument is the number of command line arguments and

The present VLSI electronic systems rely on the Silicon MOS (metal oxide semiconductor) technology which advances will soon come to saturation. Carbon nanotubes represent an advancement in the materials technology with the potential for providing switching devices that may be faster and smaller than the present MOS devices. Carbon nanotubes are miniature tube structures with

If a function is defined as a friend function in C++, then the protected and private data of a class can be accessed using the function. By using the keyword, the friend compiler knows the given function is a friend function. For accessing the data, the declaration of a friend function should be done inside

A Copy constructor is an overloaded constructor used to declare and initialize an object from another object. Copy Constructor is of two types: Default Copy constructor: The compiler defines the default copy constructor. If the user defines no copy constructor, the compiler supplies its constructor. User-Defined constructor: The programmer defines the user-defined constructor. Syntax Of

Bootstrapping in computer science is the technique for producing a self-compiling compiler. That is compiler/assembler written in the source programming language that it intends to compile. An initial core version of the compiler is generated in a different language mostly assembly language. Successive developed versions of the compiler are developed using this minimal subset of

Hadoop and Spark are the frameworks used for data processing. Both Hadoop and Spark are maintained by Apache Software Foundation. Both of these frameworks work on different principles. Hadoop is a common or popular name in the world of Big Data while Spark is still building a name for itself in a ”style”. Hadoop: Hadoop
