Defining an array globally but its parameters will available later

Question

I want to use an array from a function submit to createform.addEventListener("submit", function() { return confirm("Continue?"); }); . So, I defined it globally. But array's parameters are present in function HashTableInit. I don't want to take array by returning the function, because to use return I will need to call the whole function in printHash, and it will disturb my whole code.

HashTableInit

Here, TableSize will be available after this function executes. But how could I define array globally with parameters.

如果它不是指针，则可以使用全局值声明变量。 但在你的情况下，它是一个指针变量。您必须在分配值之前手动分配地址。因此，创建一个将值分配给指针变量的函数是一个好习惯。但是您可以分配数组和变量来全局存储数组大小。我希望它能帮助您。
