Answer:

4,096

Explanation:

Given the conditions from the questions, we have the uppercase and lowercase versions of the first four letters. Aa, Bb, Cc, Dd. This gives use a total of eight units to deal with. We also know that we have four possible slots for these eight units. If we do the math: 8 ^ 4, we get 4,096.

You do, The number of units x to the power of how how many slots there are y: So we get x ^ y

Proof it works: Say we have 10 numbers 0-9 and we have 4 slots.

Well we can use the formula from above and replace x with 10 and y with 4 Then we get: 10 ^ 4 = 10,000 which is how many possible combinations of 4 numbers.

What's the problem with this code ?
Svet_ta [14]
Hi,

I changed your program using some of the concepts you were trying to use. Hopefully you can see how it works:

#include <string>
#include <iostream>
#include <sstream>
#include <vector>
#include <algorithm>

using namespace std;

int main()
{
   short T;
   cin >> T;
   cin.ignore();

   string str[100];

   for(int i=0; i<T; i++)
   {
      getline(cin, str[i]);
   }

   for (int i = 0; i < T; i++)
   {
      stringstream ss(str[i]);
      string tmp;
      vector<string> v;

      while (ss >> tmp)
      {
          // Let's capitalize it before storing in the vector
          if (!tmp.empty())
          {
              transform(begin(tmp), end(tmp), std::begin(tmp), ::tolower);
              tmp[0] = toupper(tmp[0]);
           }
           v.push_back(tmp);
        }

        if (v.size() == 1)
        {
           cout << v[0] << endl;
        }
        else if (v.size() == 2)
        {
           cout << v[0][0] << ". "  << v[1] << endl;
        }
        else
        {
            cout << v[0][0] << ". " << v[1][0] << ". " << v[2] << endl;
        }
    }

     return 0;
}
