Array type char[] is not assignable
You can’t assign to an array, only copy to it. Use strcpy instead, like
arrays
How can I find the number of elements in an array?
I have an int array and I need to find the number of elements in it. I know it has something to do with sizeof but I’m not sure how to use it exactly.
How to sort an array in Bash
You don’t really need all that much code: Supports whitespace in elements (as long as it’s not a newline), and works in Bash 3.x. e.g.: Note: @sorontar has pointed out that care is required if elements contain wildcards such as * or ?: The sorted=($(…)) part is using the “split and glob” operator. You should … Read more
IndexError: index 10 is out of bounds for axis 0 with size 10
You try to index outside the range: Change to: And it works. You create t with length of M: So you can only access M elements in t. Python always starts indexing with zero. Therefore: will do M loops, while: will do M+1 loops.
java.lang.ArrayIndexOutOfBoundsException: 4 Error
All of your calls to arrayCharToInt[x+1] are going to go out of bounds on the last iteration of the loop they’re in (for example, if arrayCharToInt.length equals 5, the highest that x is going to go is 4. But then x+1 equals 5, which is out of bounds for an array with five cells). You’ll need to put in some sort of if( x … Read more
Java ArrayList for integers
List of Integer.
Multidimensional Vectors in C++
If you are able to use C++11, multidimensional arrays and vectors of vectors can be initialized in a similar manner. However, there are differences that must be understood to access the elements without running into undefined behavior. For a multidimensional array, memory for the elements of the array is required to be allocated contiguously. For … Read more
type any? has no subscript members
When you subscript profile with “Addresses”, you’re getting an Any instance back. Your choice to use Any to fit various types within the same array has caused type erasure to occur. You’ll need to cast the result back to its real type, [[String: Any]] so that it knows that the Any instance represents an Array. Then you’ll be able to subscript it: This is very … Read more
Badly placed ()’s error with the following shell script
It is a small error. arr= (one two three) should’ve been arr=(one two three) Also you can’t use \n in echo. Use printf if you want to use \n. And fixing the rest of the errors, the code looks like this.
Weighted random selection from array
Compute the discrete cumulative density function (CDF) of your list — or in simple terms the array of cumulative sums of the weights. Then generate a random number in the range between 0 and the sum of all weights (might be 1 in your case), do a binary search to find this random number in … Read more
