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;
}
Answer:
The offset
Explanation:
In the question, we understand that the original text is HELLO and the encrypted text is OLSSV.
It should be noted that O replaced H, L replaced E, S replaced L and V replacement O.
This is made possible by a term refered to as offset.
The offset is used to determine the character that will replace another when it is encrypted.
7 characters after H is O; this is same for every other characters in the text.
I’m here, hello. . . . . . .
Rapid prototyping as it allows the production of a functional program in a short time
