Basic data types



There are basically 5 data types :
1.Character:- It can be declared using "char".It takes 1 Byte(8 bits) of memory space. These types of variables are generally used to hold values defined by the ASCII character set i.e. any single character. Its minimal range is from -127 to 127.

2.Integer:- It can be declared using "int". It takes 2 Bytes(16 bits) of memory space. These types of variables are generally used to hold numerical values. It doesn't support the digits after decimal. Its minimal range is -32,767 to 32,767.

3.Floating point:- It can be declared using "float". It takes 4 Bytes(32 bits) of memory space. These types of variables are generally used to hold numerical values. It supports upto 6 digits after decimal. Its minimal range is from 1E-37 to +37.

4.Double:- It can be declared using "double". It takes 8 Bytes(64 bits) of memory space. These types of variables are generally used to hold numerical values. It supports upto 10 digits after decimal. it is used basically for scientific calculations Its minimal range is from 1E-37 to +37.

5.Void:- These types of variables are either explicitly declares a function as returning no value or creates generic pointers.

We can modify these basic data types by using some keywords:-
1.signed
2.unsigned
3.long
4.short

Components of C language

Image
There are five main component of C language :- 1. The character set: Any alphabet ,digit or special symbol ,used to represent information is denoted by character. The character in C are grouped into four categories:- i) Letters A...Z and a...z ii) Digits 0,1,2,.....9 iii) Special Symbol ~ ` ! @ # $ % ^ & * () . < > ? / " : ; { }[ ]. iv) White Space,blank space, Carriage return, form feed, newline, horizontal tab. C uses the uppercase letter A to Z, the lowercase letters a to z, the digits 0 to 9, and certain special characters as building blocks to form basic program elements ( e.g., constants, variables, operators, expressions, etc. Some of the special characters are listed below: + - * ~ % / & ( ) { } [ ] ? " < > ! ; : Most versions of the language also allow certain other characters, such as @ and $, to be included within strings and comments. C uses certain combinations of these characters, such as \b,\n and \t, to represent spe

Decision making using if statement

Image
The if statement is a powerful decision making statement and is used to control the flow of execution of statements. It's a basically two way decision statement and is used in conjuction with an expression. It's syntax is:- "if(test expression)" It allows the computer to evaluate the expression first and then, depending on condition, it transfers the control to a particular statement. This point of program has two paths to follow,one for the true and other for false condition.As shown in figure:-     Practical examples of if statement:- 1. if(bank balance is < 500)     deposit money 2. if(room is dark)     put on lights The if statement may be implemented in different forms depending on the complexity of conditions to be tested. The different forms of if statements are:- 1.Simple if statement 2.if....else statement 3.Nested if....else statement 4. else if ladder 1.Simple if statement.  The general form of simple if statement is
