How to display the percentage of vowels in a word?

Question

Programming

In the task, you need the program to select the word with the most vowels, and then display their percentage in the selected word. The problem is with percentages. I wanted to first count the number of vowels themselves, but here the same number always comes out, and several times. I feel I stumbled on level ground. Maybe there is an easier way?

#include <ctype.h>
#include <stdio.h>
#include <string.h>
#include<cstdlib>
 #include <iostream>
#include <conio.h>
#define max 150
using namespace std;

int main() {
    setlocale (LC_ALL, "RUS");
      cout<<"Введите слова: "<<endl;
    char input[256];
    const char* s = input;
    fgets(input, sizeof input / sizeof(char), stdin);


    while (*s && !isalpha(*s))
        s++;
    const char* result = s;
    double resultPart = .0;
    while (*s) {
        //Читаем слово.
        const char* wordStart = s;
        int vowelCount = 0, consonantCount = 0;
        while (*s && isalpha(*s)) {
            if (strchr("aeiouy", *s))
                vowelCount++;
            else
                consonantCount++;
            s++;
        }
        double part = (double)vowelCount / (vowelCount + consonantCount);
        if (part > resultPart) {
            resultPart = part;
            result = wordStart;
        }
        while (*s && !isalpha(*s))
            s++;

int n, c1=0, c2=0, c3=0, c4=0, c5=0, c6=0;
char result[max];

            for(n=0;n!=max;n++)
        {
         if (result[n]=='a')
             c1=c1+1;
         if (result[n]=='e')
             c2=c2+1;
         if (result[n]=='y')
             c3=c3+1;
         if (result[n]=='u')
            c4=c4+1;
         if (result[n]=='i')
             c5=c5+1;
         if (result[n]=='o')
             c6=c6+1;
        };
{


cout<<"Кол-во: "<<endl;
    cout<<("%d,%d,%d,%d,%d,%d",c1,c2,c3,c4,c5,c6)<<endl;

    }

    }
    cout<<"Результат: "<<endl;
    while (*result && isalpha(*result))
        putchar(*result++);
    putchar('\n');
}

Answer 1

You have two result variables. And where you count the number of letters - the result variable is empty.
Take a debugger and walk through the program - and much will become clear.

Answer 2

an easier way is to use the standard C++ containers and algorithm library. like this:

Answer 3

The algorithm is simple. Two arrays, vowels in one, consonants in the other. We are looking for consonants_count++, or vowels_count++. We count percentages. Everything.
