javascript
function setup() { // Creating Canvas of given size createCanvas(500, 90); } function draw() { // Set the background color background(220); // Initializing the source array let src = ['IT', 'CSE', 'ECE']; // Initializing the source array position // from where the elements are to be copied. let src_pos = 1; // Initializing the destination array let dst = ['Ram', 'Shyam', 'Geeta']; // Initializing the destination position // where copied elements are to be pasted. let dst_pos = 0; // Initializing the number of source array elements // which are to be copied. let length = 2; // Calling to arrayCopy() function. arrayCopy(src, src_pos, dst, dst_pos, length); // Set the size of text textSize(16); // Set the text color fill(color('red')); // Getting new destination array text("New destination array is : " + dst, 50, 30); } |
Output:
