c++ - int a = 0 and int a(0) differences - Stack Overflow

The int a (0) syntax for non-class types was introduced to support uniform direct-initialization syntax for class and non-class types, which is very useful in type-independent (template) code. In non-template code the int a (0) is not needed.

C/C++: How does int array[10]={0} work? - Stack Overflow

int& and int difference - C++ Forum - cplusplus.com

A simple program to illustrate this: Notice how "row" and "col" do not change. The example void x (int& a,int& b) is pass by reference. In this case "a" and "b" become new names for "row" and "col" and any changes in in the function to "a" and "b" are reflected back in main for the variables "row" and "col".
