Operators in C - tccicomputercoaching.com What is operator?

Operator means simple symbol which is used between operands (variable) during mathematical process.

There are following categories: 1. arithmetic: + - * / % i.e. a=6 b=2 printf("a+b =%d", a+b); printf("a-b =%d", a-b); printf("a/b =%d", a/b); printf("a*b =%d", a*b); printf("a%b =%d", a%b); op: a+b =8 a-b =4

a/b =3 a*b =12 a%b =0 Modulor Operator - % is used in Coding like ro find Number is even or Odd. if(a%2==0) { printf("a is even"); }

else { printf("a is odd"); } 2. relational operator : > >= < <= == != For example, a=6 b=2; if(a==b) { printf("a and b are same"); } else { printf("a and b are not same"); }

3. logical operator : && &&

|| ! ||

4. Assignment Operator: = This operator assign value of right side variable to the left side variable. i.e int x=10,y=20 ; printf("%d",x); x=y; printf("%d",x); op: 10 20 5. Increment and decrement: ++ - Increment ++ and decrement -- to change the value of an operand (constant or variable) by 1. Increment ++ increases the value by 1 whereas decrement -- decreases the value by 1. These two operators are unary operators, meaning they only operate on a single operand. i.e, int x=6; x++; printf("%d",x); x- -; printf("%d",x);

op: 7 6 6. Conditional operator: Syntax: exp1? exp2:exp3 I.E. int x=10,y=20 ,max; max=x>y?x:y; printf("%d" ,max); OP: 20 7. Shorthand Assignment Operator: += +* +/ +% i.e int x=6; x+=5; This statement expnad like x=x+5; x= 6+5; x=11; 8. Bitwise Operators: & | > < The Bitwise operators is used to perform bit-level operations on the operands. The operators are first converted to bit-level and then the calculation is performed on the operands. The mathematical operations such as addition, subtraction, multiplication etc. can be performed at bit-level for faster processing. For example, the bitwise AND represented as & operator in takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1. i.e Assume variable 'A' holds 60 and variable 'B' holds 13, then â&#x2C6;&#x2019; (A & B) = 12, i.e., 0000 1100 For more information about C programming at TCCI Call us @ 9825618292 Visit us @ http://tccicomputercoaching.com/
