- 3. Operators Example: 5 + 6 Operator Operands
- 4. Operators 5 * 5 + 3 28 40 BODMAS Rule is not apply in C language.
- 5. Bitwise Operators ❑ There are six types of bitwise operators ➢ Bitwise ‘AND’ (&) ➢ Bitwise ‘OR’ (|) ➢ Bitwise ‘XOR’ or Exclusive OR (^) ➢ Bitwise ‘NOT’ (~) ➢ Right Shift (>>) ➢ Left Shift (<<)
- 6. Unary Operators ❑ +, - , ++, --, sizeof( ). ❑ Unary operators are operators those required only one operand to perform operations.
- 7. Unary Operators ➢ -a, -b, -c; Negative ➢ +a, +b, +c ; Positive ➢ --a, --b,--c; Decrement Operator ➢ ++a,++b,++c : Increment Operator Unary Operator: Use will only 1 operand Binary Operator: Use will only 2 operand Ternary Operator: Use will only 3 operand
- 8. Unary Operators ➢ ++(Increment Operator) • Post Increment Operator(x++) • Pre Increment Operator(++x) ➢ --(Decrement Operator) • Post Decrement Operator(x--) • Pre Decrement Operator(--x)
- 9. Bitwise Operators ➢ Bitwise AND (&) ➢ Bitwise OR ( | ) ➢ Bitwise XOR or Exclusive OR (^) ➢ Bitwise NOT ~ ➢ Bitwise Right shift >> ➢ Bitwise Left shift <<
- 10. Bitwise Operators Bitwise AND(&) : This operator work on binary numbers . Operand Operator Operand Output 0 & 0 0 0 & 1 0 1 & 0 0 1 & 1 1 Ex: Int x; X= 23 & 56; 56 = 0000 0000 0011 1000 23= 0000 0000 0001 0111 16 = 0000 0000 0001 0000 16 2^9 2^8 2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0 9 8 7 6 5 4 3 2 1 0 If Both true then O/P will be true
- 11. Bitwise Operators Bitwise OR(|) : This operator work on binary numbers . Operand Operator Operand Output 0 | 0 0 0 | 1 1 1 | 0 1 1 | 1 1 Ex: Int x; X= 23 & 56 56 = 0000 0000 0011 1000 23 = 0000 0000 0001 0111 63 = 0000 0000 0011 1111 1+2+4+8+16+32= 63 2^9 2^ 8 2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0 9 8 7 6 5 4 3 2 1 0 If one value is true then O/P will be true.
- 12. Bitwise Operators Bitwise XOR(^) : This operator work on binary numbers . If Both operands are same than output will be 0 if different then 1. Operand Operator Operand Output 0 ^ 0 0 0 ^ 1 1 1 ^ 0 1 1 ^ 1 0 Ex: Int x; X= 23 & 56 56 = 0000 0000 0011 1000 23 = 0000 0000 0001 0111 = 0000 0000 0010 1111 1+2+4+8+32=47 2^9 2^8 2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0 9 8 7 6 5 4 3 2 1 0 Both should be different to get true value.
- 13. Bitwise Operators Bitwise Right shift (>>) : This operator work on binary numbers . Here we have to add 00 in left side Ex: Int x; X= 56>>2 56 = 0000 0000 0011 1000 Step 1: = 0000 0000 0000 1110 00 2+4+8=14 2^9 2^8 2^7 2^6 2^ 5 2^4 2^3 2^2 2^1 2^0 9 8 7 6 5 4 3 2 1 0
- 14. Bitwise Operators Bitwise Left shift (<<) : This operator work on binary numbers . Here we have to add 00 in right side Ex: Int x; X= 56<<2 56 = 0000 0000 0011 1000 Step 1: 56 = 00 0000 0000 1110 0000 32+64+128=448 2^9 2^8 2^7 2^6 2^5 2^4 2^3 2^2 2^1 2^0 9 8 7 6 5 4 3 2 1 0
- 15. Relational Operators ➢ <, >, <=,>= ( 1 ) ➢ ==, != ( 2) ➢ Here priority of set-1 is greater than set-2. ➢ Relational Operators always Yields results either 0 or 1. ➢ Every Non-zero value is true and zero value is false main() { int x; clrscr(); x = 3>4; printf(“%d”, x); } 0 Ctrl+F9 Output :
- 16. Logical Operators ➢ NOT ! ➢ And && ➢ OR || ❖ NOT ! ▪ This an unary operator. ▪ Priority level is also same as unary operator. ▪ It inverts the truth value of statement . ▪ !T = F ▪ !F = T
- 17. Logical Operators ❖ NOT ! ▪ This an unary operator. ▪ Priority level is also same as unary operator. ▪ It inverts the truth value of statement . ▪ !T = F ▪ !F = T
- 18. Logical Operators ❖ NOT ! ▪ This an unary operator. ▪ Example: main() { int x=5; clrscr(); x = !x > 4; // 0>4==0 printf(“%d”, x); } 0 Ctrl+F9 Output :
- 19. Logical Operators ❖ AND && ▪ This an Binary operator. ▪ If both operand are non zero(true) then it becomes true. Operand Operator Operand Output F && F F T && F F T && F F T && T T
- 20. Logical Operators ❖ AND && ▪ This an Binary operator. ▪ Example: main() { int x=5, y; clrscr(); y = x > 4 && x <10 ; // T && T==1 printf(“%d”, y); } 1 Ctrl+F9 Output :
- 21. Logical Operators ❖ OR || ▪ This an Binary operator. ▪ If any of the two operands is non-zero(true) then it becomes true. Operand Operator Operand Output F || F F T || F T T || F T T || T T
