In C++:

You are working for a software firm that developed a word processor. A common error users often make is that they forgot the caps locks on and print text like this: " tHIS IS A SAMPLE of an error", this usually happens at the beginning of a new section (i.e. right after a dot or in a new line).
Write a program to detect this error and fix it. The input will be a long string on keyboard.
