Question

The programmer must initialize variables when they are declared

Answer 1

Answer: When you declare a variable, you should also initialize it. Two types of variable initialization exist: explicit and implicit. Variables are explicitly initialized if they are assigned a value in the declaration statement. Implicit initialization occurs when variables are assigned a value during processing.

Explanation:

For example, in JavaScript

var PaintAmount = 50; -declare and initialize  

function setup() {

   creatCanvas(200, 200);

}  

function draw() {

   ellipse(PaintAmount, PaintAmount) -use the variable PaintAmount

}

or rather in Java,

package random;

public class something() {

Public static void Main(String []args) {

        string name;  // this is declaring the variable with the example type  

     

       string name = new string; //this initializes the declared variable

}

}
