C language operator
- 1. C language Operator PANCHAL KARTIK J COMPUTER ENGINEERING
- 3. Operator There are 8 operator 1. Arithmetic operator 2. Logical operator 3. Bitwise operator 4. increment and decrement operator 5. Relational operator 6. Assignment operator 7. Conditional operator 8. Other special operator
- 4. Arithmetic operator Operator name Meaning + Add - Subtract * Multiply / Divide % Modulo division
- 5. Program #include<stdio.h> void main() { int x = 25 , y = 5 printf(“%d + %d = %dn”, x , y , x + y ); printf(“%d + %d = %dn”, x , y , x + y ); printf(“%d + %d = %dn”, x , y , x + y ); printf(“%d + %d = %dn”, x , y , x + y ); getch(); } Output 25 + 5 = 30 25 – 5 = 20 25 * 5 = 125 25 / 5 = 5
- 6. Logical operator Operator name Meaning && Logical AND || Logical OR ! Logical NOT
- 7. Logical operator Expression Value a>b && c==5 True ! (5>3) False a<b || c>10 True (b>a) && (c!=5) False (b<c||b<a)&&(c==5) True
- 8. Bitwise operator Operator name Meaning & Bit-wise AND | Bit-wise OR ^ Bit-wise XOR << Left shift >> Right shift ~ Bit-wise 1`s complement
- 9. increment and decrement operator Increment means i++ or ++i some example i=5 than i++ in result is 6 Decrement means i-- or --I Some example i=5 than i– in result is 4 i++ and i-- is postfix ++i and --i is prefix
- 10. Relational operator Operator name Meaning == Equals != Not equals to < Less than > Greater than <= Less than or equal to >= Greater than or equal to
- 11. Assignment operator assignment operator symbol is = assignment operator is used to value to variable varname = varname operator expression ; varname operator = expression; Example 1. a = a + 5 ; a += 5;
- 12. Conditional operator It is also knows as a ternary operator it is used to Expr1 ? Expr2 : expr3 ; logical operator is true and false expr2 is true is the print to the display and expr3 is not print expr3 is true is the print to the display and expr2 is not print
- 13. Other special operator they are special operator sizeof , arrow , dot , * , & , -> etc
- 14. Simple program #include<stdio.h> #include<conio.h> void main() { int x = 10 , y , z = 0; x++; ++x; y = ++x; printf(“value of x = %d y = %d and x = %dn”, x , y , z); z = y--; printf(“value of x = %d y = %d and x = %dn”, x , y , z); getch(); } Output Value of x = 13 y = 13 and z =0 Value of x = 13 y = 12 and z = 13
