Give the output of the given code.
-10, 0
-9, -9
-7, 0
-10, -9
Answer explanation
In the context of the C programming language, ~a and !a have different meanings:
1. `~a` (Bitwise NOT):
- The `~` (tilde) operator in C performs bitwise NOT operation.
- It inverts each bit of the operand `a`.
- Example:
int a = 5; // binary: 0000 0101
int result = ~a; // binary: 1111 1010
2. `!a` (Logical NOT):
- The `!` (exclamation mark) operator in C is the logical NOT operator.
- It is used to invert the truth value of a condition or expression.
- If `a` is zero (false), then `!a` will be 1 (true), and if `a` is non-zero (true), then `!a` will be 0 (false).
- Example:
int a = 0;
int result = !a; // result will be 1 (true)
