Study Notes
Format Specifiers
- The format specifier
%urepresents an unsigned integer in C programming.
Constants
- A character constant in C programming has a specific purpose, which is to represent a single character.
- In C programming, a constant entity remains constant throughout the execution.
- A floating-point constant in C is correctly represented in the format
-digit.digitor-.digit. - A string constant in C is enclosed in double quotes.
Operators
- The format specifier
%hurepresents an unsigned short integer in C programming. - The postfix increment operator increments the value of a variable after its value is used in an expression.
- The unary minus operator changes the sign of a value.
- The
&operator is used for bitwise AND operation. - The
>operator is used for greater than comparison. - The
<operator is used for less than comparison.
Operands
- An operand in programming is a value that is operated on by an operator.
- Examples of unary operators include increment, decrement, and unary minus operators.
- The
*operator represents multiplication in the expressiona * b. - The
%operator represents the modulus operator, which returns the remainder of the division.
Operator Classification
- A binary operator requires two operands.
- A unary operator requires only one operand.
