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.
