    int i;
    int v_count=0,s_count=0,n_count=0;
    for(i=0;i<strlen(str);i++)
    {
    if(str[i]=='a' || str[i]=='A' || str[i]=='e'|| str[i]=='E' || str[i]=='i'
       || str[i]=='I' || str[i]=='o' || str[i]=='O' || str[i]=='u' || str[i]=='U')
    {
     v_count++;
    }
    else if(str[i]>='0' && str[i]<='9')
        n_count++;
    else if(str[i]>= 0 && str[i]<=47 || str[i]>= 58 && str[i]<=64 || str[i]>=91 && str[i]<=96 || str[i]>= 123 && str[i]<=127)
        s_count++;
    }
    printf("Number of digits: %d\n",n_count);
    printf("Number of vowels: %d\n",v_count);
