Consider the following program segment and answer the questions given:
for(int k=1;k<=5;k++)
System.out.println(k);
System.out.println(k);
(a) Will the program segment get executed successfully?
(b) If not, state the type of error?
(c) How do you correct the program if it has any error?

Answer
(a) No, the program segment will not execute successfully.
(b) The error is a syntax error because the variable k is not known outside the loop. The variable k is created inside the for loop and only exists there. When the program tries to use k after the loop, it does not recognize it, so the program gives an error.
(c) To fix the error, declare k before the loop:
int k;
for (k = 1; k <= 5; k++)
System.out.println(k);
System.out.println(k);
