Bitwise Operators

Bitwise Operators

A  bit-wise operators works on each bit of data. Bitwise operators are used in bit level programming.
Operators Meaning of operators
& Bitwise AND
| Bitwise OR
^ Bitwise exclusive OR
~ Bitwise complement
<< Shift left
>> Shift right

Other Operators
Comma Operator
Comma operators are used to link related expressions together. For example:
int a,c=5,d;
The sizeof operator
It is a unary operator which is used in finding the size of data type, constant, arrays, structure etc. For example:

#include <stdio.h>
int main(){
    int a;
    float b;
    double c;
    char d;
    printf("Size of int=%d bytes\n",sizeof(a));
    printf("Size of float=%d bytes\n",sizeof(b));
    printf("Size of double=%d bytes\n",sizeof(c));
    printf("Size of char=%d byte\n",sizeof(d));
    return 0;
}
Output
Size of int=4 bytes
Size of float=4 bytes
Size of double=8 bytes
Size of char=1 byte
Conditional operators (?:)
Conditional operators are used in decision making in C programming, i.e, executes different statements according to test condition whether it is either true or false.
Syntax of conditional operators
conditional_expression?expression1:expression2
If the test condition is true, expression1 is returned and if false expression2 is returned.
Example of conditional operator
#include <stdio.h>
int main(){
   char feb;
   int days;
   printf("Enter l if the year is leap year otherwise enter 0: ");
   scanf("%c",&feb);
   days=(feb=='l')?29:28;
   /*If test condition (feb=='l') is true, days will be equal to 29. */
   /*If test condition (feb=='l') is false, days will be equal to 28. */
   printf("Number of days in February = %d",days);
   return 0;
}
Output
Enter l if the year is leap year otherwise enter n: l
Number of days in February = 29
