The difference is more prominent when you are passing a big struct/class. when you use use ‘normal’ parameter, you pass the parameter by value and hence creating a copy of the parameter you pass. if you are using const reference, you pass it by reference and the original data is not copied. in both cases, … Read more
No, the structure you found is how Java handles it (that is, with overloading instead of default parameters). For constructors, See Effective Java: Programming Language Guide’s Item 1 tip (Consider static factory methods instead of constructors) if the overloading is getting complicated. For other methods, renaming some cases or using a parameter object can help. This is … Read more
There are two typical ways of declaring a function. I prefer the second approach. or To call a function with arguments: The function refers to passed arguments by their position (not by name), that is $1, $2, and so forth. $0 is the name of the script itself. Example: Also, you need to call your function after it is declared. Output: … Read more

A parameter is the variable which is part of the method’s signature (method declaration). An argument is an expression used when calling the method. Consider the following code: Here i and f are the parameters, and anInt and 2.0 are the arguments.
argv and argc are how command line arguments are passed to main() in C and C++. argc will be the number of strings pointed to by argv. This will (in practice) be 1 plus the number of arguments, as virtually all implementations will prepend the name of the program to the array. The variables are … Read more
The flag Xmx specifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xms specifies the initial memory allocation pool. This means that your JVM will be started with Xms amount of memory and will be able to use a maximum of Xmx amount of memory. For example, starting a JVM like … Read more
