What is the meaning of decrement operator?
A decrement operator, in the context of C#, is a unary operator. It returns a value of same type, with predefined value equal to the operand value minus one. The decrement operator is denoted by the symbol ‘—’. A decrement operator supports both prefix and postfix notations.
What is the decrement operator used in C++?
Increment/decrement operators

| Outside class definition | ||
| pre-decrement | –a | T& operator–(T& a); |
| post-increment | a++ | T operator++(T& a, int); |
| post-decrement | a– | T operator–(T& a, int); |
What does increment and decrement operator mean?
Increment and decrement operators are unary operators that add or subtract one, to or from their operand, respectively. They are commonly implemented in imperative programming languages. The increment operator increases, and the decrement operator decreases, the value of its operand by 1.
How do you use decrement?
The decrement operator is represented by two minus signs in a row. They would subtract 1 from the value of whatever was in the variable being decremented. The precedence of increment and decrement depends on if the operator is attached to the right of the operand (postfix) or to the left of the operand (prefix).
What does /= mean in Java?
a /= b; means divide a by b and put the result in a . There are similar operators for addition, subtraction, and multiplication: += , -= and *= . %= will do modulus. >>
Why do we use increment or decrement operator?
Increment operators are used to increase the value of the variable by one and decrement operators are used to decrease the value of the variable by one. Both increment and decrement operator are used on single operand or variable, so it is called as unary operator.
What is the dereference operator?
In computer programming, a dereference operator, also known as an indirection operator, operates on a pointer variable, and returns the location-value, or l-value that it points to in memory.
