Write a Program to find vowels, constants and digits a file using threading.

Code for Program to find vowels, constants and digits from a file using threading in C Programming

# include<stdio.h>
# include <pthread.h>

void *count();
int vowels,consonants,ok,digit;
FILE *fp;
pthread_t id;
pthread_mutex_t lock1;
main()
{
    int i,j,n_thread;
    
    fp=fopen("read1","r");
    digit=0;vowels=0;consonants=0;
    if(fp==NULL)
    {
        printf("File Reading Error");
        exit(0);
    }

    pthread_mutex_init(&lock1,NULL);
    printf("Enter the NO of Thread ");
    scanf("%d",&n_thread);
    ok=0;
    for(i=0;i<n_thread;i++)
        {
                
        
        if(0==pthread_create(&id,NULL,count,NULL))
                {
