Hey harry ! I am currently trying to pratice the c programs from the folders given in github and then I stumbled upon a problem. The quiz where we create a program to print the grade of a student based on marks, you forgot to add the printf statement. I tried to copy paste it and couldn't find the problem and asked chatgpt and I identified the problem which I had a clue to begin with. btw, thanks for teaching us to use chatgpt.
