Storage classes in C define the scope, lifetime, and visibility of variables, influencing memory management and access.
auto: Default storage class for local variables, with automatic duration. Example: 'int x;' inside a function.
register: Suggests storing the variable in CPU registers for faster access. Example: 'register int count;'
static: Preserves variable value between function calls and limits visibility to the fi...

- Q3. Logics on bit wise operators
- Ans.
Bitwise operators are used to perform operations at the bit level on binary numbers.
Bitwise AND (&) - sets a bit to 1 only if both input bits are 1
Bitwise OR (|) - sets a bit to 1 if either input bit is 1
Bitwise XOR (^) - sets a bit to 1 if the input bits are different
Bitwise NOT (~) - inverts all the bits
Left shift (<<) - shifts the bits to the left by a specified number of positions
Right shift (>>) - shifts the bits ...
- Q4. Understanding of pointers
- Ans.
Pointers are variables that store memory addresses of other variables in programming languages like C and C++.
Pointers are used to store memory addresses of variables.
They allow direct manipulation of memory locations.
Pointers can be used to pass variables by reference.
Example: int *ptr; ptr = # *ptr = 10; // num now equals 10
