Question

Please use C language with basic terms. Please fast, thank you so much :)

Write a function declared as "int categorize(char *str)" which accepts a string as an input parameter and categorize the string. The function should return the category number as decribed below: Category 1: If the string contains only capital letters (e.g. ABCDEF), the function should return 1. Category 2: If the string contains only small letters (e.g. abcdef), the function should return 2. Category 3: If the string contains only letters but no other symbols (e.g. ABCabc) the function should return 3. Category 4: If the string contains only digits (e.g. 12345), the function should return 4. Category 5: If the string contains both letters and digits but no other symbols (e.g. Hello123), the function should return 5. Category 6: Otherwise, the function should return 6. You are provided main() function for testing purposes. DO NOT MODIFY IT!

int categorize(char *str)
{
   int i=0,up=0,low=0,digit=0,length=0;
   char ch;
   while (ch != '\0')
   {
       ch = str[i];
       if (isupper(ch))
           up++;
       else if(islower(ch))
           low++;
       else if(isdigit(ch))
           digit++;
       i++;
   }
   length=strlen(str);
   if(length == up)
       return 1;
   else if(length == low)
       return 2;
   else if(length==(up+low))
       return 3;
   else if(length==digit)
       return 4;
   else if(length == (digit+low+up))
       return 5;
   else return 6;
      
}

int main()
{
   char str[100];
   scanf("%s",str);
   int c=categorize(str);
   printf("%d\n",c);
   return 0;
}
