In this technological and digital age where everything is automated. We should prefer something which saves time and space and makes our work easy. Lucky for us C++ programmers, we have switch case statements. It is a great alternative to the If else condition statement. It reduces the amount of code to a very small size which saves… Read More »
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 »
In this article, you’ll learn about strings in C programming. Strings are defined as an array of characters. The difference between a character array and a string is the string is terminated with a special character ‘\0’. Example : char name[] = “first name” ; Declaration of strings : When the compiler encounters a sequence of characters enclosed… Read More »
In this article, you’ll learn about unions in C programming. More specifically, how to create unions, access its members and learn the differences between unions and structures. User defined data type : Union Like structures in C, union is a user defined data type. In union, all members share the same memory location. Unions are conceptually similar to… Read More »
A structure is a user defined data type in C. A structure creates a data type that can be used to group items of possibly different types into a single type. Structure is similar as Array, but only difference is that array allows only similar data type that can be stored in contiguous manner, but structure can stores… Read More »
Data types define the type of data a variable can hold. C language has some predefined set of data types to handle various kinds of data that we can use in our program. These datatypes have different storage capacities. In C programming, data types are declarations for variables. This determines the type and size of data associated with… Read More »
Prerequisite – C language C standard library (libc) is the standard library for the C programming language, as specified in the ANSI C standard. C standard library is also called the ISO C library. The C library functions are provided by the system and stored in the library. The C library function is also called an in-built function… Read More »
A function is a block of code that performs a specific task. It is a set of statements that take inputs, do some specific computation and produces output. A function can be called multiple times to provide reusability and modularity to the C program. Example : Advantage of functions in C : There are the following advantages of… Read More »
