Find out the no. of words.

How many words can be formed by using all the letters of the word "DAUGHTER"
so that the vowels always come together?

Answer:
4320

Explanation:

Given word contains 8 different letters.When the vowels AUE are always together

We may suppose them to form an entity,treated as one letter.

Then,the letters to be arranged are DGHTR(AUE).

These 6 letters can be arranged in 6P6=6!=720 ways

The vowels in the group (AUE) may arranged in 3!=6 ways.

therefore Required number of words=(720 X 6)=4320.

Find the output.

void main()
{
static int i=5;
if(--i)
{
main();
printf("%d ",i);
}
}

Output: 
0 0 0 0


Explanation:
The variable 'i' is declared as static, hence memory for 'i' will be allocated
for only once, as it encounters the statement. The function main() will be called
recursively unless 'i' becomes equal to 0, and since main() is recursively called, so
the value of static 'i' ie., 0 will be printed every time the control is returned.

What is the time??

A watch was set accurately at 8.30am and then lost 2 seconds for every 5 minutes. What time was indicated on the watch at 6.30pm on the same day?

Answer:
6.26pm

Explanation:
As given the question, the watch will lost 2 seconds for every 5 minutes,
therefore, for 10min = 4 sec
                     20min = 8 sec
                     40min = 16 sec
                     60min (1 hour)= 24 sec
                     10 hours = 240 sec which is 4 min.
Therefore after 10 hours, 4 min delay will occur i.e at 6.30pm it will show 6.26pm.
