Question:
How do you detect alphabetic data being entered into an integer field from a cin statement?
Answer:
The easiest way to do that is by having cin read a string rather than an int. Then you can examine the string to detect its validity. For example:
#include#include using std::string;using std::cout;using std::cin;int main(){ bool error = false; string data; cout<<"enter your age: "; cin>>data; for (unsigned int i = 0; i< data.length(); i++) { if ( ! isdigit(data[i]) ) { cout<< "illegal input"; error = true; break; } // continue normally }}
