How are you doing the compiling and linking? You’ll need to specify both files, something like: …so that it knows to link the functions from both together. With the code as it’s written right now, however, you’ll then run into the opposite problem: multiple definitions of main. You’ll need/want to eliminate one (undoubtedly the one in … Read more
There are a few solutions to your problem. The way with MySQLi would be like this: To run database queries is also simple and nearly identical with the old way: Turn off all deprecated warnings including them from mysql_*: The Exact file and line location which needs to be replaced is “/System/Startup.php > line: 2 … Read more
Assuming your categories are in cells A1:A6 and the corresponding values are in B1:B6, you might try typing the formula =MEDIAN(IF($A$1:$A$6=”Airline”,$B$1:$B$6,””)) in another cell and then pressing CTRL+SHIFT+ENTER. Using CTRL+SHIFT+ENTER tells Excel to treat the formula as an “array formula”. In this example, that means that the IF statement returns an array of 6 values (one of each of the cells in … 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
From the Docs: Then you do
See Python PEP 8: Function and Variable Names: Function names should be lowercase, with words separated by underscores as necessary to improve readability. Variable names follow the same convention as function names. mixedCase is allowed only in contexts where that’s already the prevailing style (e.g. threading.py), to retain backwards compatibility.
In C++ you are supposed to declare functions before you can use them. In your code integrate is not declared before the point of the first call to integrate. The same applies to sum. Hence the error. Either reorder your definitions so that function definition precedes the first call to that function, or introduce a … Read more
A function is a piece of code that is called by name. It can be passed data to operate on (i.e. the parameters) and can optionally return data (the return value). All data that is passed to a function is explicitly passed. A method is a piece of code that is called by a name that is associated with … Read more
what is the purpose of having the arg1, arg2 in the parenthesis next to it? In this case, arg1 and arg2 are called arguments. Arguments allow functions to receive inputs it’s expected to use in order to perform a task. The inputs are provided by the callers. For example, in school math, you may’ve already … Read more
The main function must be declared as a non-member function in the global namespace. This means that it cannot be a static or non-static member function of a class, nor can it be placed in a namespace (even the unnamed namespace). The name main is not reserved in C++ except as a function in the … Read more
