An operator is a symbol that operates on a value or a variable. For example: + is an operator to perform addition. C has a wide range of operators to perform various operations.

What does i ++ mean in C?

In C, ++ and — operators are called increment and decrement operators. They are unary operators needing only one operand. Hence ++ as well as — operator can appear before or after the operand with same effect. That means both i++ and ++i will be equivalent. i=5; i++; printf(“%d”,i);

* is the indirection operator in C and C++. Whenever it is used, it indicates that the variable next to it is a pointer containing the address of another variable.

Remarks. The logical OR operator ( || ) returns the boolean value true if either or both operands is true and returns false otherwise. The operands are implicitly converted to type bool before evaluation, and the result is of type bool . Logical OR has left-to-right associativity.
