Conflict between counting words from a file and other functions

Question

I need to make a progress as described in the image. I was able to do all the steps, but I couldn’t get the word count to run along with the other processes.

I followed the code:

#include <stdio.h>
#include <string.h>

FILE *arq;

int ContarPalavras(char *sub)
{
    char frase[100];
    int qntd = 0;
    
    while(!feof(arq))
    {
        fgets(frase, 100, arq);
        sub = strtok(frase, " .!,");
        while(sub != NULL)
        {
            sub = strtok(NULL, " ");
            qntd++;
        }
    }
    
    return qntd;
}

int main(void)
{
    int qntdCarac = 0, qntdLinhas = 0, qntdPalavras = 0;
    char c;
    char *sub;
    int a = 0, b = 0, C = 0, d = 0, e = 0, f = 0, g = 0, h = 0;
    int i = 0, j = 0, k = 0, l = 0, m = 0, n = 0 ,o = 0, p = 0;
    int q = 0, r = 0, s = 0, t = 0, u = 0, v = 0, w = 0, x = 0, y = 0, z = 0;
    
    arq = fopen("doc.txt", "r");
    
    while((c = getc(arq)) != EOF)
    {
        qntdCarac++;
        if(c == '\n')
        {
            qntdLinhas++;
        } else if(c == ' ')
            {
                qntdPalavras++;
            }
        switch(c)
            {
                case 'a':

                case 'd':
