C operators ppt
- 1. Pt. Mohan Lal SD College For Women Gurdaspur TOPIC : C Operators Created by: Mrs. Rajni Asst. Prof. in Computer Science
- 2. What is an operator An operator is a symbol that tells the computer to perform certain mathematical or logical manipulations. These operators are used in programs to manipulate data and variables
- 3. C Operators 1. Arithmetic operators 2. Relational Operators 3. Logical Operators 4. Assignment Operators 5. Increments and Decrement Operators 6. Conditional Operators 7. Bitwise Operators 8. Special Operators
- 4. Arithmetic operators Operator Meaning + Addition or Unary Plus – Subtraction or Unary Minus * Multiplication / Division % Modulus Operator
- 5. Integer Arithmetic Let x = 27 and y = 5 z = x + y 32 z = x – y 22 z = x * y 115 z = x % y 2 z = x / y 5
- 6. Floating point arithmetic Let x = 14.0 and y = 4.0 then z = x + y 18.0 z = x – y 10.0 z = x * y 56.0 z = x / y 3.50
- 7. Relational Operators Operator Meaning < is less than <= is less than or equal to > is greater than >= is greater than or equal to == is equal to != is not equal to
- 8. Relational Expressions 6.5 <= 25 TRUE -65 > 0 FALSE 10 < 7 + 5 TRUE
- 9. Logical Operators Operator Meaning && Logical AND || Logical OR ! Logical NOT
- 10. Find out the answer a > b && x = = 10 a < m || a < n ! (x >= y) a = 5 b = 4 x=10, y = 9 m=6 n = 3
- 11. Assignment Operators Statement with simple Statement with assignment operator shorthand operator a = a + 1 a += 1 a = a – 1 a -= 1 a = a * (n+1) a *= (n+1) a = a / (n+1) a /= (n+1) a = a % b a %= b
- 12. Increment and Decrement OperatorsTwo most useful operators which are present in 'c' are increment and decrement operators. Operators: ++ and –- The operator ++ adds one to the operand The operator -- subtracts one from the operand. Both are unary operators and can be used as pre or post increment/decrement
- 13. CONDITIONAL OPERATORS These conditional operator are used to construct conditional expressions of the form. Syntax: exp1?exp2:exp3. where exp1,exp2,exp3 are expressions. Operator: ?: (ternary operator)
- 14. BITWISE OPERATORS These operators works on bit level Applied to Integers only OPERATOR MEANING & Bitwise AND | Bitwise OR ^ Bitwise Exclusive OR << Shift Left >> Shift Right
- 15. SPECIAL OPERATORS C' supports some special operators such as comma operator, sizeof operator and pointer operators. Comma operator: the comma operator is used to combine related expressions. A comma linked list of expressions are evaluated left to right and the value of right most expression is the value of combined expression.. Example: value=(x=10, y=5, x+y)
- 16. SPECIAL OPERATORS Sizeof Operator Sizeof is an operator used to return the number of bytes the operand occupies. Syntax: m=sizeof(sum); k=sizeof(2351);
