output:
To compile the program, run the gcc command,

$ gcc p45.c

Now the executable file is stored as a.out, to run
the program,

$ ./a.out
Enter a operator :*

Arithmetic operator *
$ ./a.out
Enter a operator :^

Bitwise operator ^
$ ./a.out
Enter a operator :$

Not an valid input
$ ./a.out
Enter a operator :|

Bitwise operator |
$ ./a.out
Enter a operator :!

Logical operator !
$ ./a.out
Enter a operator :#

Not an valid input
$ ./a.out
Enter a operator :?

Ternary operator ?
$ ./a.out
Enter a operator :!=

Logical operator !
$
