End of file is a function which returns zero value at end of file... EOF is a deliminator

End of Line refers to the 'n'( new line character). It will perform operations till it come across 'n'. EOF refers to End of File. It is the last character in the file.(if it is not empty). If the file is empty then only EOF will be present.Some compilers give its value as -1.

Write function vowels to count the vowels and letters
Write function vowels to count the vowels and letters in free text given as string. Then print out the number of occurrences of each of the vowels a, e, i, o and u in the string, the total number of letters, and each of the vowels as an integer percentage of the letter total.
Suggested output format is:
Numbers of characters:
a 3 ; e 2 ; i 0 ; o 1 ; u 0 ; rest 17Lokesh M

This ques tests your knowledge of operator precedence and associativity
* and ++ operator have same precedence and their associativity is right to left.
That is why first (*p) is evaluated which results 5 then (++*p) i.e. (++5) is evaluated which gives us 6Meena Goel
- Sep 12th, 2007
The answer for this question is 6. in starting the value of x is 5 that will be incremented by pointer p.
