C - Loops

for(int i = 2; i <= 6; i += 2) {
    printf("%d ", i);
}

A2 4 6

B2 3 4 5 6

C2 4 6 8

D0 2 4 6

Step-by-Step Solution

Solution:

Step 1: Analyze loop initialization and condition
Loop starts at i=2, runs while i ≤ 6, incrementing i by 2 each time.
Step 2: List values of i during iterations
Values: 2, 4, 6. After 6, next i=8 which breaks condition.
Final Answer:
2 4 6 -> Option A
Quick Check:
Loop prints even numbers 2 to 6 [OK]

Quick Trick: Increment by 2 prints even numbers [OK]
