C++ [9999] Question

Question

#include <iostream>
#include <string>
using namespace std;

int
main ()
{

int userInput;
bool trueValue = true;
cout << "Welcome to the Calculator that can only count up to 4 digits." <<
endl;
cout << "If you would like to view the current sum, please type [TOTAL]" <<
endl;
cout << "Enter 9999 to [EXIT]." << endl;
while ((userInput < 9999 || userInput == "TOTAL") && trueValue)
{
if (userInput == "TOTAL")
{
cout << userInput << endl;
}
else
{
cout << "Please enter a number:" << endl;
cin >> userInput;

if (userInput == 9999)
{
trueValue = false;
}
else
{
trueValue = true;
userInput += userInput;
}

}
return 0;
}
}

How would I be able to compare both a integer and string for my condition, I'm thinking of parsing the input but I'm not sure how.

Answer 1

If i understood your question you want to combine strings? just parse your input into strings instead of integer, though that will cause the adding of numbers to not work(1+1=11). to change that you should create an if statement that will check if the input is numbers or chars. if its numbers than consider this as a number, if its a char consider it as a string. regrading syntax, i cannot help you with that with C. wait for help from an other user.
