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
File:c:\program files\microsoft visual studio 10.0\vc\include\xstring
Line:1441
Expression: string subscript out of range
For information on how your program can cause assertion failure, see the Visual C++ documentation on asserts.

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;

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
