Hi, I'm writing this program that after validating the user input to be an integer, it validate it to more than zero and be less or equal to 40. My code does validate entry for being an integer but after that i'm stuck. i want to check if the entry is 0

#include  #include  #include  using namespace std; int validateHoursWorked(string str1, int& userNumber); int main() { string str1; int userNumber; cout<<"Enter the requested information for each employee."< 0, try again "; getline(cin, str1); entryLenghth=str1.length(); counter=0; } else { counter++; } } counter = 0; //convert the string into numeric value for //numeric operations while (counter < entryLenghth) { someChar = str1[counter]; if(isdigit(someChar)) { usernumber = usernumber*10 + (someChar - '0'); } counter++; } return userNumber; }
