Question

Hello, I am still trying to figure out a problem that I was given about 2 weeks ago (it was due last week). I have most of it figured out (with help from this site) except for one part..

Say there are multiple lines, and you want to delete a line that doesn't include certain characters :

a house is blue
the dog is brown
i read a history book
etc.(there are a lot more than 3 lines, but an example for these three lines would be great)

I want to read through a line, search for the characters "a" and "h", and delete any line that does not include an "a" and "h".

For the above example, the output would be:

the dog is brown

I know how to read an input file and copy the output to another file, so it is just the code that would help with this example that I need. I have access to the string.h library, which I think may have the functions I need to complete this problem?

Thanks for your help and I will definitely rate any helpful answers

Explanation / Answer

You could use the strchr which is part of string.h. If the 'a' letter was not in the char then it would return a null pointer. So for example you could do: char buffer[] = "the dog is brown"; if(strchr(buffer,'a') != null || strchr(buffer,'h') != null) { cout
