Array Manipulation

In the previous screen, we learned the basics of arrays. Now, let's dive into array manipulation, which involves performing operations such as creating, accessing, and modifying elements in an array.

Creating an Array

To create an array in C++, you define the type of the elements followed by the name of the array and the size of the array in square brackets. For example:

TEXT/X-C++SRC

1int myArray[5];

xxxxxxxxxx
 
#include <iostream>
using namespace std;
​
int main() {
  // Create an array
  int myArray[5];
​
  // Assign values to the array
  for (int i = 0; i < 5; i++) {
    myArray[i] = i + 1;
  }
​
  // Accessing elements of the array
  cout << "Element at index 2: " << myArray[2] << endl;
​
  // Modifying elements of the array
  myArray[3] = 10;
​
  // Displaying the modified array
  for (int i = 0; i < 5; i++) {
    cout << myArray[i] << " ";
  }
  cout << endl;
​
  return 0;
}
