If you define 'c' and 'd' just as double variablesdouble c, d;you will send them to the function by reference using '&' symbol like this:pointerIntro(first, second, &c, &d);. To assign values to 'c' and 'd' in your function, you must dereference the pointer using the following...

When calling a function, arguments appear on the right of the function name, inside parentheses. The declaration of a function requires the parameters in the same place. The same pattern for functions is clearer in K&R (pre-standard) C. K&R syntax looks like this: ...

In Go, arrays can be passed to functions as arguments. However, when an array is passed to a function, it is passed by value, meaning a copy of the array is made. To modify the original array, a pointer or slice should be used. ...
11/27/2012 There are two ways that a function argument, or parameter, can be passed to it: by value or by reference. In the first instance, a copy of the
