Checking for non-numeric input and assigning to a double in C++?

Question

Here is the code I have at the moment:

char ch;
int sum = 0;
double values[10];
int i = 0;
cin >> ch;

while (!isalpha(ch))
{  
    values[i] = ch; 
          


        

Answer 1

string stream should be able to do the conversion for you. A pass through atoi could also get the job done.
