Working with the Array

Reminder how to access an array by index

cpp

main

copy

              
12345678910

            
#include <iostream>

int main()
{
	int myArray[3] = { 67, 23, 87 };

	std::cout << myArray[0] << std::endl;
	std::cout << myArray[1] << std::endl;
	std::cout << myArray[2] << std::endl;
}

Note

Index counting starts from zero, making the first element in a list or array the zeroth element.

Opgave

Swipe to start coding

  • Declare a string array with a size of 5;
  • Initialize the array with the following values:
    • First element: "!";
    • Second element: "World";
    • Third element: ",";
    • Fourth element: "Hello";
    • Fifth element: " ".
  • Construct the message by arranging the elements of the array in the correct order ("Hello, world!")and then set it to the value of the message variable;
  • Output the constructed message.
