A naturally abundant, nonmetallic element that occurs in all organic compounds and can be found in all known forms of life. Diamonds and graphite are pure forms, and carbon is a major constituent of coal, petroleum, and natural gas. Carbon generally forms four covalent bonds with other atoms in larger molecules. Atomic number 6; atomic weight 12.011; sublimation point above 3,500°C; boiling point 4,827°C; specific gravity of amorphous carbon 1.8 to 2.1, of diamond 3.15 to 3.53, of graphite 1.9 to 2.3; valence 2, 3, 4. See Periodic Table. Related forms carbonaceous adjective.
Following table shows all the logical operators supported by C language. Assume variable A holds 1 and variable B holds 0, then − OperatorDescriptionExample&&Called Logical AND operator. If both the operands are non-zero, then the condition becomes true.(A && B) is false. Called Logical OR Operator.

If any of the two operands is non-zero, then the condition becomes true.(A B) is true.!Called Logical NOT Operator. It is used to reverse the logical state of its operand. If a condition is true, then Logical NOT operator will make it false.!(A && B) is true.ExampleTry the following example to understand all the logical operators available in C −.
