There are several flavors of arrays, depending on how and where they are declared. Fixed-length Arrays Fixed-length arrays must have their size determined at compile time. You cannot change the size of a fixed-length array after it has been defined. Fixed-length arrays are declared in one of the following ways: In the first three cases, … Read more
I don’t understand the problem you have since an ArrayList implements a List with List being an interface. You can change this line to:
CODE 1 CODE 2 CODE 1 and CODE 2 both give same output. but argument 2 of main function in CODE 1 and CODE 2 are different. Array of pointers are created above data section at compile time. argv is array of pointers. Then we should declare argument in main function as pointer to pointer … Read more
Verilog thinks in bits, so reg [7:0] a[0:3] will give you a 4×8 bit array (=4×1 byte array). You get the first byte out of this with a[0]. The third bit of the 2nd byte is a[1][2]. For a 2D array of bytes, first check your simulator/compiler. Older versions (pre ’01, I believe) won’t support … Read more
Take a look here:Edit: The referenced source (allexperts.com) has since closed, but here are the relevant author comments: There are many algorithms available on the web for sorting. The most versatile and usually the quickest is the Quicksort algorithm. Below is a function for it. Call it simply by passing an array of values (string … Read more
Knuth left this as an exercise (Vol 3, 5.2.5). There do exist in-place merge sorts. They must be implemented carefully. First, naive in-place merge such as described here isn’t the right solution. It downgrades the performance to O(N2). The idea is to sort part of the array while using the rest as working area for merging. For example … Read more
To iterate over all the key-value pairs in a table you can use pairs: outputs: Edit: Note that Lua doesn’t guarantee any iteration order for the associative part of the table. If you want to access the items in a specific order, retrieve the keys from arr and sort it. Then access arr through the … Read more
This is not how you initialize an array, but for: The first declaration: char buf[10] = “”; is equivalent to char buf[10] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; The second declaration: char buf[10] = ” “; is equivalent to char buf[10] = {‘ ‘, 0, 0, 0, 0, 0, 0, … Read more

Define mutable array OR: OR if you need an array of predefined size (as mentioned by @0x7fffffff in comments): Change element at position OR Change sub array OR OR If you had 3×2 array of 0(zeros) before these changes, now you have: So be aware that sub arrays are mutable and you can redefine initial … Read more
