Question

Difference between pointer variable and normal variable

Answer 1

A pointer is just like an int: a number. It happens to be a number that identifies a memory location, and if something is stored in that memory location you can call it an address. Like an int, a pointer can be stored in a variable. A variable that stores a pointer could be called a pointer variable.

.X is a normal randomvariable, μ is the mean, σ is the standard deviation, π is approximately 3.14159, and e is approximately 2.71828. The random variable X in the normalequation is called the normalrandom variable. The normalequation is the probability density function for the normal distribution. .
