C++ Question

repeat code automatically

I wrote some code to convert any string to Morse code. The code works perfect until I try repeating it automatically.

Whether I use "while" or "do while" the code runs only once and then it terminates.
Would you help to find out what the problem is?

int main ()
{
cout<<"Enter the string: ";
char myStr[81];
char ch='y';

while (ch=='Y'||ch=='y')
{
getString(myStr);
toUpper(myStr,strlen(myStr));
removeSpace(myStr);
getMorse(myStr,strlen(myStr));
cout<<"to repeat press Y/y";
cin>>ch;
}
return 0;
}


I added the getString() function

void getString(char myStr[])
{
cin.getline(myStr,81,'\n');
}

Answer

After the user enters input, they press enter. That newline character '\n' is still in the cin stream. You need to ignore it:

cin >> ch;
cin.ignore(numeric_limits<streamsize>::max(), '\n'); //this ignores all subsequent characters until the newline character
