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

I have tested with gcc & VS and it is ...

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".
