can you explain in brief what is "r+" mode in a file... i
know that it si used to read and modify rhe existing
content.... but explalanation about the file pointer in "r+"
mode i wann to know???????????
actually i have 2 years teaching experience as computer
faculty but now i am a DBA but when i go for interview many
peoples asked me why i left my teaching profession and why
i want to come in this field kindly give me the proper
answer of this queston
1.What is a Data Structure? Explain its need?
2.What is a Directed Graph? Write an algorithm to find
whether a Directed Graph is connected or not?
3.Explain the process of converting a Tree to a Binary Tree.
how do you redirect stdout value from a program to a file?

Write the following function in C.
stripos — Find position of first occurrence of a case-
insensitive string
int stripos ( char* haystack, char* needle, int offset )
Returns the numeric position of the first occurrence of
needle in the
haystack string. Note that the needle may be a string of
one or more
characters. If needle is not found, stripos() will return -
1.
The function should not make use of any C library function
calls.
Write an interactive c program that will encode or decode a
line of text. To encode a line of text, proceed as follows:
Convert each character, including blank spaces, to its
ASCII equivalent.
Generate a positive random integer. Add this integer to the
ASCII equivalent of each character. The same random integer
will be used for the entire line of text.
Suppose that N1 represents the lowest permissible value in
the ASCII code, and N2 represents the highest permissible
value. If the number obtained in step 2 above exceeds N2,
then subtract the largest possible multiple of N2 from this
number, and add the remainder to N1. Hence the encoded
number will always fall between N1 and N2, and will
therefore always represent some ASCII character.
Display the characters that correspond to the encoded ASCII
values.
The procedure is reversed when decoding a line of text. Be
certain, however, that the same random number is used in
decoding as was used in encoding.
