text: I'm trying to make encryption program but when i run the program it gives me this error:
  Debug Assertion Failed!
  Program:...nts\visual studio 2010\projects\encrypter\debug\encrypter.exe

  For information on how your program can cause assertion failure, see the Visual C++ documentation on asserts.
  #include <iostream> #include <stdlib.h> #include <sstream> #include <string> #include "windows.h" using namespace std; void encrypt(string words); int main() { string Emptywords; cout << "What shall i encrypt?" << endl; cin >> Emptywords; encrypt(Emptywords); // calling encryption funtion and passing user input } void encrypt(string words) { char A [100]; //char array for letters that user typed in char B [100]; //char array for encrypted letters string C; //string what will contain in the end encrypted message for (int n=0;n<=99 ;) // this for loop is going to encrypt the letters { A[n] = words[n]; // words[n] = checking for what letters user entered switch( A[n] ) // switch statement to encrypt the letter that a has { case 'a': B[n] = 'c'; break; case 'b': B[n] = 'd'; break; case 'c': B[n] = 'e'; break; case 'd': B[n] = 'g'; break; case 'e': B[n] = 'j'; break; case 'f': B[n] = 'l'; break; case 'g': B[n] = 'ö'; break; case 'h': B[n] = 'a'; break; case 'i': B[n] = 'k'; break; case 'j': B[n] = 'y'; break; } n++; // increasing n by 1 } for(int n = 0; n <= 10 ;) // for loop that will but the message inside C { stringstream ss; string encrypt; ss << B[n]; n++; if(n = 99) { ss >> encrypt; string C = encrypt; } n++; // increasing n by 1 } cout << C << endl; // showing the result to the user Sleep(5000); }
  The error message comes right after i type in couple letters and press enter and yes i have checked that they are all letters that the program knows
  is there a rule that im not aware?
  i have tried to figure out what is the problem with out any success for 3 hours now
  Pardon my imperfect english.
  i wish someone who is wiser than me could tell me what am i doing wrong
  thanks in advance
