CS50 Week 2 Problem Set 2 Readability

Problem Set 2 - Readability

In coding, problems have different ways to get to the solution. Below code is one way. Soon, we will be posting different codes.

** Remember:

Try to change some things in the code before submitting it in order to avoid being rejected as Harvard academic honesty.

The Solution:

#include <cs50.h>

#include <stdio.h>

#include <string.h>

#include <math.h>

#include <ctype.h>

int main(void)

{

    // inintiate needed variables

    string text = get_string("TEXT: ");

    int letters = 0;

    int words = 1;

    int sentences = 0;

    for (int i = 0; i < strlen(text); i++)

    {

        if (isalpha(text[i]))

        {

            letters++;

        }

        else if (text[i] == ' ')

        {

            words++;

        }

        else if (text[i] == '.' || text[i] == '?' || text[i] == '!')

        {

            sentences++;

        }

    }

    // Initiate variables needed to construct the formula

    float L = (float) letters / (float) words * 100;

    float S = (float) sentences / (float) words * 100;

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

    if (index < 1)

    {

        printf("Before Grade 1\n");

    }

    else if (index > 16)

    {

        printf("Grade 16+\n");

    }

    else

    {

        printf("Grade %i\n" , index);

    }

}
