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

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");   
}

Write the output of the following program segment:

for(int a = 1; a <= 10; a++) 
{ 
if(a % 2 == 0) 
continue; 
System.out.print(a + "  "); 
}
