What are the expressions in the C language?
Common expressions found in the C language include:
- Arithmetic expressions involve combinations of operators such as addition, subtraction, multiplication, division, and modulus.
- Relational operators: Used to compare the size of two values, including equal, not equal, greater than, less than, greater than or equal to, and less than or equal to operators.
- Logical expressions are used to combine multiple relational expressions, including logical AND (&&), logical OR (||), and logical NOT (!) operators.
- Assignment expression: used to assign a value to a variable, done by using the assignment operator (=).
- Conditional expression: use the ternary operator (?:) to choose different values based on the truth of the condition.
- Bitwise operations involve using bitwise operators to perform operations on individual bits, including bitwise AND (&), bitwise OR (|), bitwise XOR (^), left shift (<<), and right shift (>>).
- The sizeof expression is used to determine the size of a variable or type.
- Type conversion expression: using the cast operator to convert one type to another.
- Function call expression: calling a function and passing arguments by adding parentheses and parameters after the function name.
- Array access expression: Utilize the subscript operator ([]) to access elements within an array.
- Pointer operation expression: Using the pointer operator (*) to access the value pointed to by the pointer or to access members of a structure through the pointer.
- Expression combination: Utilize parentheses to group multiple expressions, altering the order of operations or enhancing readability.
