Hello, im making siiimple C++ encryption / decryption program. here's the code:
now the decryption part works, but when I try to encrypt what ever, it will just skip the user input part. Why is that?
Code:
#include <iostream >
void encrypt( char [ ] );
void decrypt( char * ePtr );
int main( )
{
char vaihto [50];
char vastaus;
std::cout << "do you wanna crypt or decrypt?\n c/d" << std::endl;
std::cin >> vastaus;
if (vastaus == 'k')
{
std::cout << "write text you would like to encrypt" << std::endl;
std::cin.get(vaihto, 49);
std::cout << "you wrote: " << vaihto << std::endl;
encrypt( vaihto );
std::cout << "encrypted: " << vaihto << std::endl;
system("pause");
return 0;
}
else if (vastaus == 'd')
{
std::cout << "write the string you would like to decrypt" << std::endl;
std::cin.get(vaihto, 49);
decrypt( vaihto );
std::cout << "Decrypted string is: " << vaihto << std::endl;
system("pause");
return 0;
}
else
std::cout << "answer properly!" << std::endl;
system("pause");
}
void encrypt (char e[] )
{
for( int i=0; e[i] != '\0'; ++i ) ++e[i];
}
void decrypt( char * ePtr ) {
for( ; * ePtr != '\0'; ++ ePtr ) --(* ePtr);
}
:D
