[ SOLVED ] My program fail in some cases , how to fix it ?

Question

Here I'm for asking about one of my code.

Code : https://code.sololearn.com/c4oIOfzTUeV3/?ref=app

CHECK CODE I'VE EXPLAINED THERE IN DETAILS

I've checked it for 9 cases,

Case1+2+3: When your searching word is present at the starting/middle/ending of the sentence.

Case4+5+6: case1/2/3+it is a substring of a word which start that word in sentence.

Case7+8+9: case1/2/3+and it is a substring of a word which end that word in sentence.

In SoloLearn , Case 3 , 6 and 9 are not giving expected output it fail if the searching word is at end of the sentence ,

it's working fine in my phone's compiler , an app named CODING C.
You can test in CODING C so you can be sure , I'm right.

I've posted it in QnA because I wanted to know why this code is not working properly in same cases while working in other compiler .

I know it's because there are some restrictions in SoloLearn compilation but I don't know which and how fix !

I've provided the code , read question carefully and give it try.

Thanks MARTIAN TAYLOR 🙏

Answer 1

SEE THIS ,
I've explained my question in code , I can't do that here because of 1024 characters limitations 😅.
So if you wanna know details , see the code then 👍.

Answer 2

Martin Taylor 1st case you mentioned has been solved already ,
2nd case you mentioned was not in my requirement however i have a diffrent way to for that result approach.
Thanks for your guidence , thanks for that hint too ☺️👏

Answer 3

Martin Taylor thanks your suggestions worked 😊👍
I've understood now why it fails , actually I'm using fgets and fgets store \n too and that cause the error .
for punctuation characters I can use their ASCII value to filter but this is not in requirement for now .
I've checked your profile and it seems like your professional in c/cpp 😀.
it will be beneficial to learn from you 😊.

Answer 4

Martin Taylor i realize the library function , however i was instructed to not use that . And thanks for the answer of 183 line , i wish to try it and give you feedback.
