IMPORTANCE OF C

IMPORTANCE OF C

The increasing popularity of C is probably due to its many desirable qualities.
It is a robust language whose rich set of built-in functions and operators
can be used to write any complex program. The C compiler combines the capabilities of an assembly language with the features of a high-level language and therefore it is well suited for writing both system software and
business packages. In fact, many of the C compilers available in the market are written in C.
    Programs written in C are eficient and fast. This is due to its variety of data types and powerful operators. It is many times faster than BASIC. For example, a program to increment a variable from O to 15000 takes about one second in C while it takes more than 50 seconds in an interpreter BASIC.
    There are only 32 keywords in ANSI C and its strength lies in its built-in functions. Several standard functions are available which can be used for developing program
   C is highly portable. This means that C programs written for one computer can be run on another with little or no modification. Portability is important if we plan to use a new computer with a different
operating system.
    C language is well suited for structured programming, thus requiring the user to think of a problem in terms of function modules or blocks. A proper collection of these modules would make a complete
program. This modular structure makes program debugging, testing and maintenance easier.


    Another important feature of C is its ability to extend itself. A C program is basically a collection of functions that are supported by the C library. We can continuously add our own functions to C library. With the availability of a large number of functions, the programming task becomes simple.

Loop In C Language

Loop In C Language  A loop statement allows us to execute a statement or group of statements multiple times. Given below is the general form of a loop statement in most of the programming languages − C programming language provides the following types of loops to handle looping requirements. Sr.No. Loop Type & Description 1 while loop Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body. 2 for loop Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable. 3 do...while loop It is more like a while statement, except that it tests the condition at the end of the loop body. 4 nested loops You can use one or more loops inside any other while, for, or do..while loop. While Loop in C A while loop is the most straightforward looping structure. While loop syntax in C programming language is as follows: Syntax of While Loop in C: while (condition) { st...

Why use C?

Why use C? C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C might be − • Operating Systems • Language Compilers • Assemblers • Text Editors • Print Spoolers • Network Drivers • Modern Programs • Databases • Language Interpreters • Utilities

Loops in C programming with example

Loops in C programming with example A loop is used for executing a block of statements repeatedly until a given condition returns false. Example of For loop #include <stdio.h> int main () { int i ; for ( i = 1 ; i <= 3 ; i ++) { printf ( "%d\n" , i ); } return 0 ; } Output: 1 2 3 Nested For Loop in C Nesting of loop is also possible. Lets take an example to understand this: #include <stdio.h> int main () { for ( int i = 0 ; i < 2 ; i ++) { for ( int j = 0 ; j < 4 ; j ++) { printf ( "%d, %d\n" , i , j ); } } return 0 ; } Output: 0 , 0 0 , 1 0 , 2 0 , 3 1 , 0 1 , 1 1 , 2 1 , 3 Example of while loop #include <stdio.h> int main () { int count = 1 ; while ( count <= 4 ) { printf ( "%d " , count ); count ++; } return 0 ; } Output: 1 2 3 4 Example of while loop using logical operator In this example...
