Algorithms

Definition: -

Algorithm is a stepwise solution to any problem which is used in programming to create a knowledge of steps to write a program.

  1. A sequential solution of any program that written in human language, called algorithm.
  2. Algorithm is first step of the solution process, after the analysis of problem, programmer write the algorithm of that problem.
As Algorithm goes in sequence it is written in steps for example: -

Write a algorithm to find out number is odd or even?
Ans. 

step 1 : start
This Represents Starting of Algorithm.
step 2 : input number
This is for input which is inserted by user or given in program by default.
step 3 : rem=number mod 2
rem is defined as variable which is storing the Result of number mod 2
step 4 : if rem=0 then
               print "number even"
           else
               print "number odd"
           endif
This step contains the whole solution to find the number is odd or even
step 5 : stop                                                       
This step indicates that algorithm is finished or stopped.

Constants

Image
The constants  are the values which never changes. The C uses following types of constants. Integer constants :                 Integer constants represent the whole numbers. They uses digits 0 to 9 and optional sign + or - before the number. The following are examples of valid integer constants. 123 -23 65535 0 +85                 The space, comma and other special symbols are not allowed. The following are examples of invalid integer constants. 10,000  $500 15 780 Real Constant :                 Real Constants represent the numbers with fractional parts i.e digits after decimal point. They are used to represent contiguous quantities like temperature of day. The following are examples of valid real constants. 0.0005 -0.123 +248.0 215. .78  Character Constants : Character constants represent single character and are always enclosed in single quotes. The following are examples of valid character constants. 'A'         'a'

Data Types in C Programming

There are four basic data types supported by C. Table lists the basic data types with their size in bytes and the range of values. Type Size In bytes   Range   char   1 -128 to +127   int   2   - 32768 to +32767 float 4 3.4e-38 to 3.4e+38 double 8 1.7e-308 to 1.7e+308 The C provides different qualifiers like signed , unsigned , short and long. By applying the qualifiers to the basic data types, we can change the range of our data type as per need. Table lists the various data types available by applying the qualifiers to the basic data types with their size and range of values.  Type Size in bytes Range char(signed char) 1 -128 to +127 unsinged char 1 0 to 255 int(signed int) 2 -32768 to +3

Identifiers

The identifiers are user defined names used in programs for providing names to variables, arrays and functions. The identifiers are made up of letters(uppercase and lowercase), digits and underscore(_). For Example, int max ; //max is an identifier which have datatype integer int max2; //this is second identifier of same datatype string max_3; //you can also use identifier like this with different datatype and underscore float 4max ; //you can not declare identifier like this this will generate an error The C is case sensitive and hence the uppercase and lowercase letters are not treated as same. For Example, int max=20 ;// this is a different variable which assigns a value 20 to max int Max=10 ; //this is different variable which assigns a value 10 to Max Identifiers also used to identify functions. For Example, int Add() ; //this is a Function which is created for addition of two integer; Program Aim : - This Program will help you to understand how the functio
