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

3 1 4 2

Reason — To return the sum of first 10 natural numbers, we must follow the proper sequence of statements:

1. int sum = 0, i; – Declare the variables sum and i, and initialize sum to 0.
2. for(i=1; i<=10; i++) – Start the loop to go through numbers 1 to 10.
3. sum+=i; – Add the current number i to sum during each loop iteration.
4. return sum; – After the loop completes, return the total sum.
