Question

InputString: "I am unwell" "We need to go to the doctor" "How long will it take?".

OutputString: I am unwell We need to go to the doctor How long will it take?

The string needs to cleaned of all occurrences of the char " . I can think of the following approacg

1. Use, strchr() function finding first occurrence of "
2. Move all characters in the string left by once position.

Repeat steps 1 and 2 , until strchr() returns a NULL pointer.

I feel this is very inefficient way to approach this problem. I need to know , if there are other methods to achieve this? Pseudo code or actual code will both be appreciated.
