Prerequisite – C language C Preprocessor is not a part of the compiler, but is a separate step in the compilation process. Preprocessors are programs that process our source code before compilation. C Preprocessor is just a text substitution tool that instructs compiler to do required pre-processing before actual compilation. All preprocessor commands begin with a hash symbol… Read More »

This program checks whether the input year is leap year or not. A leap year is exactly divisible by 4 except for century years (years ending with 00). The century year is a leap year only if it is perfectly divisible by 400. Leap Year : If a year is divisible by 4, 100 and 400 then it… Read More »
The scope of a variable x is the region of the program in which uses of x refers to its declaration. In C, all identifiers are lexically(or statically) scoped. Scoping in C is generally divided into two classes: Static Scoping, and Dynamic scoping. Static Scoping : Static scoping is also called lexical scoping. Static scope refers to the… Read More »
