How to initialize array to 0 in C?
Global variables and static variables are automatically initialized to zero. If you have simply at global scope it will be all zeros at runtime. But actually there is a shorthand syntax if you had a local array. If an array is partially initialized, elements that are not initialized receive the value 0 of the appropriate type. You … Read more
How to convert int[] to Integer[] in Java?
I’m new to Java and very confused. I have a large dataset of length 4 int[] and I want to count the number of times that each particular combination of 4 integers occurs. This is very similar to counting word frequencies in a document. I want to create a Map<int[], double> that maps each int[] to a running count … Read more
Python Array Rotation
So I am implementing a block swap algorithm in python. The algorithm I am following is this: Initialize A = arr[0..d-1] and B = arr[d..n-1] 1) Do following until size of A is equal to size of B a) If A is shorter, divide B into Bl and Br such that Br is of same … Read more
Random shuffling of an array
Using Collections to shuffle an array of primitive types is a bit of an overkill… It is simple enough to implement the function yourself, using for example the Fisher–Yates shuffle:
Add an object to an Array of a custom class
If you want to use an array, you have to keep a counter which contains the number of cars in the garage. Better use an ArrayList instead of array:
Excess elements in char array initializer error
I guess you want to make arrays of pointers instead of arrays of characters. Try this:

In C arrays are passed as a pointer to the first element. They are the only element that is not really passed by value (the pointer is passed by value, but the array is not copied). That allows the called function to modify the contents. Now, if what you want is changing the array itself … Read more
Zero an array in C code
C99 [$6.7.8/21] If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have … Read more
Shifting array to the right – homework
You can do something like: I only modified your: letters.length-1 into letters.length-2 and printed the array. Another, easier approach is to use, System.arraycopy like: To print the array you can also use:
