Errors not printing correctly..Is this logic flow correct? c++
- by igor
Example user input:
PA1 9 //correct
PJ1 9 //wrong, error printed "Invalid row" because it is not between A and I
PA11 9 //wrong, error printer "Invalid column" because it is not between 1 and 9.
The problem I am having is that it should clear the remaining input and then ask for the user to enter the "move" again, and it is not.
Where did I go wrong? I've been at it for a while and still got no progress..
void clearInput()
{
cin.clear();
}
bool getCoords(int & x, int & y)
{
char row;
while(true){
cin>>row>>y;
row=toupper(row);
if(/*(id=='P' || id=='p' || id=='D' || id=='d') && */row>='A' && row<='I' && isalpha(row) && y>=1 && y<=9){
x=row-'A';
y=y-1;
return true;
}
else if(!(y>=1 && y<=9)){
cout<<"Invalid column\n"<< endl << endl;
cout<<y;
clearInput();
cout<<y;
//return false;
}
else{
cout<<"Invalid row\n"<< endl << endl;
clearInput();
//cout<<x<<y;
//return false;
}
}
}
