Operators In C
Operators In C - An Operator Is Simply A Symbol That Is Used To Perform Operation. Operators Are The Symbols Used With Variables Or Operands To Perform A Specific Task.
Operators Precedence Of Priority
If The Expression Has Two Operands, The Operator With Highest Priority Executes First. If The Expression Has Two Operands With Same Priority, Then The Execution Happens Left To Right.
Types Of Operators
There Are Two Types Of Operators Unary Operator Binary Operator 1.Unary Operator ++(increment operator)==> increases value by 1 --(decrement operator)==> decreases value by 1 Unary Operators Are Ouse With One Operand. 2.Binary Operator They Are Used With Two Operands Based On The Task. They Are Divided Into Many Types. a) Arthematic Operators They Are Used To Perform Arthematic Operations. Arthematic Operators - + - * / % b) Comparison Or Relational Operators These Operators Which Are Used To Compare Values Of A Variable With The Value Of Another Variable. , =, ==, , != ,/= c) Logical Operators They Are Used To Check More Than One Condition. Logical Operators - , && , || , ! Example : (a>b)&&(a>c) !(a>b)||(b>c) !(a>b)
In &&(AND) Operator If Both The Conditions Are True Answer Will Be True. In || (OR) Operator If Any One Is True Answer Will Be True Assignment Operator It Is Used To Assigning The Value. Example Is = Compound Assignment Or Arthematic Assignment Operator It Calculates And Then Assigns The Value Example :- int a=10; a+=10 -> a=a+10 -> a=10+10 -> a=20 a-=10 -> a=a-10 -> a=10-10 -> a=0 a*=2 -> a=a*2 -> a=10*2 -> a=20 a%=2 -> a=a%2 -> a=10%2 -> a=0 Special Type Operators & Is Used To Get The Address Of A Variable. Is Used To Declare The Variable As A Pointer Variable. sizeof() Is Used To Know The Size Of The Datatype. Example:- Write A Program To Print The Size Of An Integer. #include #include voidmain() { int i; clrscr(); printf("size of i variable is %d ",sizeof (i)); getch(); } Result : Size Of i variable is 2 Comments They Are Used To Provide Information About Lines Of Code. It Is Widely Used To Documenting The Code. There Are Two Types Of Comments In C Language. 1.Single Line Comments - They Are Represented By // Example //............................// 2.Multiline Comments - They Are Represented By Example /*........... ............ ............ ...........*/ Read the full article
