I’m very new to C++ and was trying to initialize a large 2d zero array. However, if I run this it gives no errors but "test a" is not printed. Anyone know what I’m doing wrong? #include<iostream> using namespace std; int main(){ cout << "test a" << endl; int arrone[60480][12] = {}; } Source: Windows ..

I know how to code with C, however, this is my first time I try to use C++. And the use of VLAs(Variable Length Arrays) is not allowed in C++. So how can I convert this program using C++ standard containers( for example std::vector) for the same instead of going the C route? Instead of ..
#include <iostream> using namespace std; class ArrayDefine { private: int n; // int *arr = NULL; public: ArrayDefine(int a) { n = a; cout << "this is called" << endl; } // arr = (int *)malloc(n * sizeof(int)); int arr[n]; void elementAdd() { for (int i = 0; i < n; i++) { cout << ..
Start of the question Your program will have a class called FlightController that is going to be derived from two base classes which are called LaunchController and LandingController. The FlightController class inherits all accessible data fields and methods from the LandingController and LaunchController classes. Inside the FlightController class, you will define an object of type ..
This is for a coding test where I have the function definition static bool exists (int ints[], int size, int k) { } The goal is to return true if k is in ints else return false. Using std library one could do this. static bool exists (int ints[], int size, int k) { return ..
#include <iostream> using namespace std; int main() { string str,reverse;`enter code here` cin >> str;int j=0; for (int i = str.length() – 1; i >= 0; i–) { reverse[j]=str[i]; j++; } cout << reverse; return 0; } Output:/home/keith/builds/mingw/gcc-9.2.0-mingw32-cross-native/mingw32/libstdc++-v3/include/bits/basic_string.h:1067: std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::operator[](std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::size_type) [with _CharT = char; _Traits = std::char_traits; _Alloc = ..
I want to pass a stack array without creating new variable. Here how it looks now: void testFunc(int array[]) { } int main() { int testArray[5] = {1, 2, 3, 4, 5}; testFunc(testArray); return 0; } I am using C++17, but cant use std classes like vector. Compound literals (testFunc((int[]){1, 2, 3, 4, 5});) from ..
I want to create a N*N array with default value -1 in cpp, I tried many ways like memset, fill, fill_n but non of them worked… here’s my code: N = 10; int **m = new int*[N]; for(int i = 0; i < N; ++i) { int a[N]; fill_n(a, N, -1); for(int j = 0; ..
int arr[3] = { 1,2,3 }; cout <<"the address of the first element: "<< (int)arr << endl; cout <<"(the address of the first element)+1: " <<(int)arr + 1 << endl; cout << "(the value of the address of the first element)+1: " << *(arr + 1) << endl; cout <<"the value of the address of ..
