Why does my goto doesn't work? (C Programming) 

#include <stdio.h>
#include <Windows.h>

int main()
{
    char string[100000];
    int words, numbers, others, i;

    Jason:

    words = numbers = others = i = 0;

    printf("Please insert Characters to be calculated!");
    gets(string);

    while (string[i] != '\0')


    {
        if ((string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z'))
        {
            words++;
        }
        else if (string[i] >= '0' && string[i] <= '9')
        {
            numbers++;
        }
        else
        {
            others++;
        }

        i++;
    }

    while (string != ' ') goto Jason;
    {
        if (string == ' ') {
        printf("You have tpyed total of %d Words, %d Numbers, %d Blanks / Symbols.", words, numbers, others);
        }
    }


    Sleep(100000000);
    return 0;
}

I'm not entirely sure what you're trying to do near the end, but the conditions you're checking for seem a bit backwards. In my changes below I assumed that you are wanting to go to your "Jason" label if the string is empty, and print the calculations if the string is not empty.

On a side note, your "words" variable may be more appropriately names "letters" since it seems to be calculating the number of letters in the string, and not full words.

#include <stdio.h>
#include <Windows.h>

int main()
{
    char string[100000];
    int letters, numbers, others, i;

    Jason:

    letters = numbers = others = i = 0;    

    printf("Please insert Characters to be calculated!");
    gets(string);

    while (string[i] != '\0')


    {
        if ((string[i] >= 'a' && string[i] <= 'z') || (string[i] >= 'A' && string[i] <= 'Z'))
        {
            letters++;
        }
        else if (string[i] >= '0' && string[i] <= '9')
        {
            numbers++;
        }
        else
        {
            others++;
        }

        i++;
    }

    if (string == ' ') 
    {    
      goto Jason;
    }
    if (string != ' ') {
      printf("You have tpyed total of %d Letters, %d Numbers, %d Blanks / Symbols.", letters, numbers, others);
    }


    Sleep(100000000);
    return 0;
}
