Question

2-Write test programs in java to determine the scope of a variable declared in a for statement. Specifically, the code must determine whether such a variable is visible after the body of the for statement

Answer 1

Answer:

See Explaination

Explanation:

public class testscope

{

//start of main function

public static void main(String[] args)

{

//varible declration

int i;

int x;

//loop for 10 times

for(i=0; i<10; i++)

{

//initialize value of x to 10

x = 10;

}

//the scope of variable x is visible outside of for loop

System.out.println("The value of x is: "+x);

}

}

See attachment for sample output

nb:

You can clearly see in the output of Java program the value of x is not printed and program return errors. It means the variable x declared inside for loop does not has scope outside the for loop.
