how to initialize dynamic array in c++ code example
Example 1: declare dynamic array c++
int main()
{
int size;
std::cin >> size;
int *array = new int[size];
delete [] array;
return 0;
}
Example 2: initialize dynamic array c++ to 0
int *arrayName = new int[10]{0};
for(int i=0; i<10; i++ { cout<<arrayName[i] <<" "; }
Example 3: dynamic array cpp
#include <iostream>
#include <cstddef>
int main()
{
std::cout << "Enter a positive integer: ";
std::size_t length{};
std::cin >> length;
int *array{ new int[length]{} };
std::cout << "I just allocated an array of integers of length " << length << '\n';
array[0] = 5;
delete[] array;
return 0;
}
Example 4: c++ dynamic array
new T[size]
