I dont understand this at all! PLZ help me
1 answer:
Answer:
See explanation
Explanation:
Given
Solving (a):
print(ex[0:2])
This prints the elements from 0 index to 2-1
In other words, it prints index 0 and 1
Hence, the output is [5, 3]
Solving (b):
ex.append(8) --> This adds 8 to the end of the list
print(ex) --> This prints the updated list: [5, 3, 0, 1, 2, 8]
Solving (c):
ex.remove(0) --> This removes 0 from the list
print(ex) --> This prints the updated list: [5, 3, 1, 2, 8]
Solving (d):
ex.pop() --> This removes the last ite, from the list
print(ex) --> This prints the updated list: [5, 3, 1, 2]

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.
