Find first in C++

To find the first element of an array in C++, you can simply use the index operator [] with an index of 0. Here's some example code:

``c++ #include using namespace std;


int main() {

  int arr[] = {1, 2, 3, 4, 5};

  int firstElement = arr[0];

  cout << "The first element of the array is: " << firstElement << endl;

  return 0;

}



In this example, we first declare an integer array arr with five elements and initialize its values. Then, we use the index operator [] to access the first element of the array (which has an index of 0) and assign its value to a variable called firstElement. Finally, we print out the value of firstElement to the console. The output of this code will be:


The first element of the array is: 1
