What is meant by initialization in programming?

In computer programming, initialization is the assignment of an initial value for a data object or variable. The manner in which initialization is performed depends on programming language, as well as type, storage class, etc., of an object to be initialized.

Why is it important to initialize variables in C++?

Thus, initialization is very important. If variables are not initialized, then atleast the variable values must be overwritten to erase the garbage data and have a valid value for the variable which will ensure that the program gives the desired output. Initialization is where you give a variable an initial value.
