C is a structured programming language developed by Dennis Ritchie in 1973 at Bell Laboratories. It is one of the most popular computer languages today because of its structure, high-level abstraction, machine independent feature. C language was developed with UNIX operating system, so it is strongly associated with UNIX, which is one of the most …
It is a robust language with rich set of built-in functions and operators that can be used to write any complex program. The C compiler combines the capabilities of an assembly language with features of a high-level language. Programs Written in C are efficient and fast. This is due to its variety of data type …

Lets see how to write a simple c program #include <stdio.h> #include <conio.h> int main() { printf(“Hello,World”); getch(); return 0; } Different parts of C program. Pre-processor Header file Function Variables expression Comment All these are essential parts of a C language program. Pre-processor #include, the first word of any C program. It is also …
C programming language provides many of the built-in functions to read given input and write data on screen, printer or in any file. scanf() and printf() functions #include<stdio.h> #include<conio.h> void main() { int i; printf(“Enter a value”); scanf(“%d”,&i); printf( “\nYou entered: %d”,i); getch(); } When you will compile the above code, it will ask you …
C language syntax specify rules for sequence of characters to be written in C language. The rule specify how character sequence will be grouped together to form tokens. A smallest individual unit in c program is known as C Tokens. Tokens are either keyword, identifier, constant, variable or any symbol which has some meaning in …

Keywords are preserved words that have special meaning in C language. The meaning has already been described. These meaning cannot be changed. There are total 32 keywords in C language. auto double int struct break else long switch case enum register typedef const extern return union char float short unsigned continue for signed volatile default …
Operators are the foundation of any programming language. Thus the functionality of C language is incomplete without the use of operators. Operators allow us to perform different kinds of operations on operands. In C, operators in Can be categorized in following categories: Arithmetic Operators (+, -, *, /, %, post-increment, pre-increment, post-decrement, pre-decrement) Relational Operators (==, …
A variable is a name that may be used to store a data value. Unlike constant, variables are changeable, we can change value of a variable during execution of a program. A programmer can choose a meaningful variable name. Example : average, height, age, total etc. Rules to define variable name Variable name must be …

Decision making is about deciding the order of execution of statements based on certain conditions or repeat a group of statements until certain specified conditions are met. C language handles decision-making by supporting the following statements, if statement switch statement conditional operator statement goto statement Decision making with if statement The if statement may be …
Switch statement is used to solve multiple option type problems for menu like program, where one value is associated with each option. The expression in switch case evaluates to return an integral value, which is then compared to the values in different cases, where it matches that block of code is executed, if there is …
n any programming language, loops are used to execute a set of statements repeatedly until a particular condition is satisfied. How it Works A sequence of statements are executed until a specified condition is true. This sequence of statements to be executed is kept inside the curly braces { } known as the Loop body. …
In C language, arrays are reffered to as structured data types. An array is defined as finite ordered collection of homogenous data, stored in contiguous memory locations. Here the words, finite means data range must be defined. ordered means data must be stored in continuous memory addresses. homogenous means data must be of similar data …
string is a sequence of characters that is treated as a single data item and terminated by null character ‘\0’. Remember that C language does not support strings as a data type. A string is actually one-dimensional array of characters in C language. These are often used to create meaningful and readable programs. For example …
In C language, each variable has a storage class which decides scope, visibility and lifetime of that variable. The following storage classes are most oftenly used in C programming, Automatic variables External variables Static variables Register variables Automatic variables A variable declared inside a function without any storage class specification, is by default an automatic …
A function is a block of code that performs a particular task. There are times when we need to write a particular block of code for more than once in our program. This may lead to bugs and irritation for the programmer. C language provides an approach in which you need to declare and define …
Functions are called by their names. If the function is without argument, it can be called directly using its name. But for functions with arguments, we have two ways to call them, Call by Value Call by Reference Call by Value In this calling technique we pass the values of arguments which are stored or …
Whenever we need to pass a list of elements as argument to the function, it is prefered to do so using an array. But how can we pass an array as argument ? Lets see how to do it. Declaring Function with array in parameter list There are two possible ways to do so, one …
Structure is a user-defined data type in C which allows you to combine different data types to store a particular type of record. Structure helps to construct a complex data type in more meaningful way. It is somewhat similar to an Array. The only difference is that array is used to store collection of similar …

typedef is a keyword used in C language to assign alternative names to existing types. Its mostly used with user defined data types, when names of data types get slightly complicated. Following is the general syntax for using typedef, typedef existing_name alias_name Lets take an example and see how typedef actually works. typedef unsigned long …
Unions are conceptually similar to structures. The syntax of union is also similar to that of structure. The only differences is in terms of storage. In structure each member has its own storage location, whereas all members of union uses a single shared memory location which is equal to the size of its largest data …
