How many times the for statement given below is executed?

for(k = 10; k >= 0; k--)

1. 10
2. 11
3. 12
4. 0

Consider the following program segment in which the statements are jumbled. Choose the correct order of the statements to return the sum of first 10 natural numbers.

for(i=1; i<=10; i++)  → 1
return sum;           → 2
int sum = 0, i;       → 3
sum+=i;               → 4

1. 1 2 3 4
2. 3 4 1 2
3. 1 4 2 3
4. 3 1 4 2

Evaluate the given expression when x = 4.

x *= --x + x-- + x;

Convert the following switch case into if else if:

switch(x) 
{ 
case 'T' : 
case  't'  : System.out.print("Teacher");  break; 
default  :  System.out.print("Student");   
}
