Programming C

Operator Precedence It determines which operator is performed first in expression with more than one operator with different Precedence .   Operator Associativity It is used when two operators of same same precedence operator in an expression , it can be left to right or viceversa . 

There are “8” different types of operators are present in “C language”. Arithmetic Operator [+.-,*,/,%] Relational Operator [<,>,<=,>=,==,!=] Logical Operator [&&,||,!] Assignment Operator and short hand [+=,-=,*=,/=,%=] Increment and Decrement Operator [++(Increment Opertor),- -(Decrement Operator)] Bitwise Operator { &(bitwise And) , | (bitwise or) , ^ (Exclusive or) , ~ (Complement) , shift Operator [<<

Data Type int void char float double Size(Bits) 2 bytes or 16 bits // 4 bytes or 32 bits 1 bytes or 8 bits 1 bytes or 8 bits 4 bytes or 32 bits // 8 bytes or 64 bits 8 bytes or 64 bits Ranges 32768 to 32767 or 2,147,783,648 to 2,147,483,647 Nothing 128

What is Datatype ? If we want to store any data inside a variable , first we have to mention it’s datatype . Datatype is a way of representing data . Data Types are classified into 2 types . Primitive Data Type :- Primitive Data Type Is known as built in data type . Example:-

Variable is a container where we will store out data . Variable is a memory location inside RAM . Rules for define a variable name :  1 .  Allowed Character   All alphabets are allowed (A-Z and a-z) Numbers are allowed(0-9) Only one special symbol is allowed (_) Except (_) others are not allowed  Example:-  abc=90

” Dev c++ ” is the best software for C language .   1 . Link : https://sourceforge.net/projects/orwelldevcpp/files/latest/download  2. db click – -> next – – > next – – > next 3. Create a folder  4.Search dev C++ 5. Open 6. Create a new file in dev C++(ctrl + n) 7. Save it in that

Step by step process to solve a particular problem  is call algorithm . Example -1 : Add 3 numbers and print the result . Solution : Step-1 : Value Of a,b,c                     Step-2: Add= a+b+c                   Step-3: Print Add
