#include <iostream>
using namespace std;
char caesar( char );
int main()

{
int option;
do
{

cout << "1) Criptarea Cesar " << endl;
cout << "2) Underconstruction" << endl;
cout << "Please select an option : ";

cin >> option;
if (option == 1)
{
{
string input;
do {
cout << "Enter cipertext and press enter to continue." << endl;
cout << "Enter blank line to quit." << endl;
getline(cin, input);
string output = "";
for(int x = 0; x < input.length(); x++)
{
output += caesar(input[x]);
}
cout << output << endl;
} while (!input.length() == 0);
} //end main

char caesar( char c )
{
if( isalpha(c) )
{
c = toupper(c); //use upper to keep from having to use two seperate for A..Z a..z
c = (((c-65)+13) % 26) + 65;
}
//if c isn't alpha, just send it back.
return c;
}

return 0;

}

alta varianta la limita dar nu inteleg altceva

}

}

int main(int argc, char *argv[])
{
int i = 1;
if (argc > 1)
i = atoi(argv[1]);
else
prima();
while (i != 0)
{
if (i == 9) prima();
cin >> i;


if (i == 3) meniu3();
if (i == 8) despre();
}
if (i == 0) iesire();

}

cand sterg if (i == 3) meniu3(); si int meniu3() dau run si merge.

cand imi bag programu nu mai merge

wtf

Putin complex din cate vad (imi cer scuze daca intr-adevar este). Dar cred ca rezultatul este cea ce cauti.

Atentie: Necesita un compiler recent. GCC 4.7+ sau VS 2013+ (posibil sa functioneze si pe un compiler mai vehi dar nu garantez)

Testat pe MinGW GCC 4.9.2 x32
