int main()

{

    char line[150];

    int i, vowels, consonants, digits, spaces;

    vowels =  consonants = digits = spaces = 0;

    printf("Enter a line of string: ");

    scanf("%[^\n]", line);

    for(i=0; line[i]!='\0'; ++i)

    {

        if(line[i]=='a' || line[i]=='e' || line[i]=='i' ||

           line[i]=='o' || line[i]=='u' || line[i]=='A' ||

           line[i]=='E' || line[i]=='I' || line[i]=='O' ||

           line[i]=='U')

        {

            ++vowels;

        }

        else if((line[i]>='a'&& line[i]<='z') || (line[i]>='A'&& line[i]<='Z'))

        {

            ++consonants;

        }

        else if(line[i]>='0' && line[i]<='9')
