Question

You are writing a program that defines a variable within a loop, and then tries to use that variable outside the loop. However, the program does not run as intended. What is the issue?

Answer 1

The Variable is out of scope

Step-by-step explanation:

In programming variables exists with scopes This could be local or global. When a variable is declared as a global variable it is available to all methods and procedures in the program. Java programming language as well as C++ and several others use the open and close braces to define the scope in programs. consider the following example

public class ANot {

public static void main(String[] args) {

int i = 0;

while ( i<10){

int sum = 0;

sum = sum+i;

}

}

}

In this example, the variable i is global and can be assessed within the while loop but the variable sum is local to the while loop and cannot be assessed outside of it
