So would like to create an 2D array of characters for testing purposes. Here is my code. const int rows = 4; const int columns = 6; //char field[rows][columns]; //fill_field(rows,columns,field); char field[rows][columns] = { "A BCD ", "B CDA ", "C DAB ", "D ABC " }; I’m getting error saying "variable-sized object may not… Read More C How to create an 2d array of characters?
So I’m working with this struct type with variable length array member, like this: struct Entry; struct Data { int members; size_t entries_size; Entry entries[1]; }; The entries_size member is the actual size of the entires array, it is only known when read from network. The problem is that I’d like to use it in… Read More struct with variable length array in std::variant
Is there a funtion to find the length of array in python? Sorry I am a very beginner in python. Thanks for your help. Smith >Solution : use the len() function arr = [1,2,3] print(len(arr)) prints 3 len(s) Return the length (the number of items) of an object. The argument may be a sequence (such… Read More Length of array in python
#include <stdio.h> int main() { int n; scanf("%d", &n); int L[n]; // … return 0; } I’m asking if I can give the number of elements in an array as needed using a variable . The teacher told us that this method is not recommended and I did not understand why. Thanks for answering for… Read More can we give the number of elements in an array as needed without using a variable?
I have no idea why suddenly the value of integer is changing even though there’s no process of caluclation, here’s the code of my program : #include <iostream> using namespace std; int main() { int n; int a[] = {}; int b[] = {}; cin >> n; cout << "\n"; for(int i=0;i<n;i++) cin >> a[i];… Read More The value of integer is changing without any calculation
learning the C programming language and reading the documentation with Xcode 13.2 open and a Command-Line Tool project in front of me. Reading this, in the Declarations/Arrays/Variable Length Arrays section: { int n = 1; label: int a[n]; // re-allocated 10 times, each with a different size printf("The array has %zu elements\n", sizeof a /… Read More Why is this C array giving the "Expected Expression" error?
