C_OPERATORS
Demonstrate C Operators

C_OPERATORS is a C program which demonstrates the use of the built-in operators in C.

In C, operators include the arithmetic operators:

• +, for addition;
• -, for subtraction;
• *, for multiplication;
• /, for division (real and integer versions);
• %, for the remainder.

• <<, the left shift operator, which multiplies by powers of 2;
• >>, the right shift operator, which divides by powers of 2;
• &, the bitwise AND;
• |, the bitwise OR;
• ^, the bitwise exclusive OR;
• ~, the ones complement;

• !, the logical negation;
• &&, the logical AND;
• ||, the logical OR.

• ++, increments by 1;
• --, decrements by 1;
