Previous Year Question (PYQs)
What is the output of the following C code segment?
int i;
for(i = 0; i <= 2; i++)
{
switch(i)
{
case 1: printf("%2d", i);
case 2: printf("%2d", i); continue;
default: printf("%2d", i);
}
}
Solution
Solution:
Let’s analyze iteration by iteration —
**Iteration 1:** `i = 0`
→ `switch(0)` → goes to `default:` → prints `0`.
**Iteration 2:** `i = 1`
→ executes `case 1:` → prints `1`
→ no `break`, so it falls through to `case 2:` → prints `1`
→ encounters `continue;` → skips remaining statements in the `for` loop body and proceeds to next iteration.
**Iteration 3:** `i = 2`
→ executes `case 2:` → prints `2`
→ `continue;` moves control to the next iteration, but loop ends because `i <= 2` condition fails.
Final output:
`0 1 1 2`
