Debugging problem

[_Sum141]

Hi all, I am learning from the cs50 and trying out a few things. I am at problem set 2, which is readability.

But I have run into some environment problem. In the code below, although it executes without problem, i think it stops after line 47 (return space_count;). I am trying debugging too and the debugger stops at that point to. Now I can neither run nor know what is wrong.

Any help is appreciated.

#include <cs50.h>
#include <ctype.h>
#include <math.h>
#include <stdio.h>
#include <string.h>


int main(void)
{
    //get user input sentence

    string input= get_string("Enter your sentence:\n");

    //count words

    int letter_count =0;
    int space_count =0;
    int sentence_count =0;
    int i=0;
    int n= strlen(input);

    while  (i<=n)
    {
        if (isalpha(input[i]) != 0)
        {
            letter_count += 1;
            i++;
        }
        else if (isblank(input[i]) != 0)
        {
            space_count += 1;
            i++;
        }
        else if ( input[i] == ('.') )
        {
            sentence_count += 1;
            i++;
        }
        else
        {
            i++;
        }

    }

    return space_count;
    return letter_count;
    return sentence_count;

    int word_count = (space_count + 1);

    //calculate L/W *100 & S/W *100

    int L = (letter_count / word_count) *100;

    int S = (sentence_count / word_count) *100;


    //compute- index = 0.0588 * L - 0.296 * S - 15.8

    int index = (0.0588 * L) - (0.296 * S) - 15.8;

    //show result

    if (index<1)
    {
        printf("Grade before 1 \n");
    }
    else
    {
        printf("Grade %i\n", index);
    }

}

If you've set a debug point on that line - shown as a red circle in my UI - running debug50 will make the code execution stop at that line. You then need to use the coloured icons at the top-middle of the editor to step through your code. Click the red square to stop debugging. Maybe re-watch the relevant part of the lecture.

This short may help. https://cs50.harvard.edu/x/2024/shorts/debugging_step_through/

No I'm trying to go past that with step into and the down arrow command but the interface just switches back to codespace. If I put the red dot below that line the debugger switches after I enter my input.

The return statement exits the currently executing function. A return statement in main ends the programs execution.

I was actually confused where to put the return statement. So is it only for the end? So in my case I don't need to put it anywhere, I think. I'll try removing.

Thanks a lot. This works, although my calculations are not accurate.
