Can anyone help?
Please, can anyone tell me what is wrong with my simple encrypter?
Thank you!Code:#include <iostream.h> #include <fstream.h> int main() { char string[256], note2[256]; int b; cout<<"Write your note:"<<endl; cin.getline(string, 256, '\n'); cout<<"loading..."<<endl; for(int a=0;a<256;a++) { b=(int)string[a]; note2[a]=(char)(b+15); } ofstream a_file("note.txt"); a_file<<note2; a_file.close(); cout<<"Your note is now encrypted into the file: 'note.txt'"<<endl; cin.get(); return 0; }

> for(int a=0;a<256;a++)
1. You don't use strlen() to only output the number of chars you typed in
2. There is no \0 at the end of the string you create
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
I understood the first answer, but I didnt understand the second, I am a complete noob.
thanks

note2[a] = '\0';
When you get to the end of the string
