| Question 22 |
Consider the following program fragment
if(a > b)
if(b > c)
s1;
else
s2;
s2 will be executed if
if(a > b)
if(b > c)
s1;
else
s2;
s2 will be executed if
| a <= b | |
| b > c | |
| b >= c and a <= b | |
| a > b and b <= c |
Question 22 Explanation:
Here, possibility to happen “dangling if” error. But according to else statement it is matched with above if statement only.
We can write code segment is like this because to avoid “dangling if”
if(a>b)
{
if(b>c)
{ s1; }
else
{ s2; }
}
→ To execute s2, it (a>b) should be TRUE. And it (b>c) should be FALSE.
Hence, Option-D is correct
