Q1. find and replace a word in a text file .
Fristly, ask the user to input a file name and input the word which you want to find and replaced and then the result should be stored in a new file which need the user to input a new file name.

Q2.write a C program to do the spell checking in a file which is input by the user and then the correct spelling is in an another file, which is also input by the user. And print out which word is wrong spell in the given file .

you are not supposed to ask full programs here...you should try it out yourself..and if you have specific doubt , then ask in the forum.
