What Is Variable Initialization – Complete Guide
https://gamedevacademy.org/what-is-variable-initialization-complete-guide/
WEBNov 20, 2023 · Variable initialization is the process where a variable is assigned an initial value at the time of its creation. This step is essential in programming as it ensures that the variable does not contain any unpredictable data, known as ‘garbage value’, and behaves as expected in the program.

WEBApr 28, 2014 · Initialization. Initialization refers to the "assignment" of a value, at construction time. For a generic object of type T, it's often in the form: T x = i; but in C++ it can be: T x(i); or even: T x {i}; with C++11. Conclusion. So does it mean definition equals declaration plus initialization? It depends. On what you are talking about.
