Pset2 Readability test fail "complex single sentence" Grade 9 instead of Grade 8
What is happening there, is that you did your word count asuming that the next caracter would be alphabetical, here: al = isalpha(text[i + 1]);, but in this case, the next caracter are quotation marks ...

cs50 question. Pset2 Readability
You have to add } at the end, and in the middle before float l = 100 / words * letters; to close out the for loop.

The variables that you create in the for loops only exist within that for loop.

pset2 readability. cannot compile although int is declared and code is complete. could someone please look into?
It's a scope problem: When you declare a variable inside a 'for' loop or a function, it only will be available until the loop/function ends. For example in your for loop: for(int i=0;text[i]!='\0';i++)...

Readability assignment, getting "Segmentation fault" message
Have a look at your evaluation condition for your loop:

The net result of this condition is simply that i will get incremented by 1 each loop. The comma operator has the lowest precedence ...

There are several problems.
First, the word count is off by 1. Hint: is the code actually reading the end of string marker?

the reason that your program is not working is because you are decrementing words with each question mark and exclamation point. If you remove words--; from your program, it works correctly!

count_letters is a function. count_letters("Some text") is an int. You've got the %i flag in your printf statement, so you need an int as the second argument. That's why it's not compiling.

Why doesnt this code function?
The code doesn't work because num_letters is 0. The for loop will never run. In fact, it won't compile either because i and len are not created/defined before attempting to use them.

Readability program printing the whole sequence of a counted letter/number/word, rather than just the sum
The printf executes for every i because it is inside the for loop. If it should only execute when the for loop is complete, it needs to be outside the block (ie after the closing }).
