C++ follow up...?

After spending some more time with this, the code now works. I would like some help in coding the error statement.


1) If the user enters an age, say below 1 or exceeding 120, the user shd get an error message "Warning, age must be between 1 and 120" hence(!(1%26lt;=ageValue%26amp;%26amp;ageValue%26lt;=120)), and then the user must be prompted again to enter a valid age.


2) If the user enters a non-int value, the message is "Error: invalid entry" and prgm exits the loop. Where would be best to input these two messages? THANKS!





/ reading values printing out input in reverse

I had to make some more changes to your code. I placed comments around the changes that I made.





#include%26lt;iostream%26gt;


using namespace std;


const int MAX=1000;


/* moved to here so all functions can use them */


int ageValue[MAX];


int count=0;








/* new function */


void inputAge()


{


cout%26lt;%26lt;"Enter the age of the youngest family member:"%26lt;%26lt;endl;


cin%26gt;%26gt;ageValue[count];





/* Error 2) */


if (!cin)


{


/* not exactly sure what you want done here. */


/* to exit program */


cout%26lt;%26lt;"Your other message!"


exit(1);





/* to only stop input, and then print the other values out


change the return value to a bool and return false */


/* return false; */


}


/* Error 1) */


else if (ageValue[count]%26lt;1||ageValue[count]%26gt;120)


{


cout%26lt;%26lt;"Your error message!"%26lt;%26lt;endl;


/* recall this method */


inputAge();


}


}








int main()


{





char choice;





/* call to new function */


inputAge();





cout%26lt;%26lt;"Are there any more family members?(Y for yes and N for no)"%26lt;%26lt;endl;


cin%26gt;%26gt;choice;








/* Placed in the below while instad of the for.*/


while (choice=='Y'||choice=='y')


/*for(count=1; choice=='Y'||choice=='y'; count++)*/


{


/* Added the count increment here */


count++;





/* call to new function */


inputAge();





cout%26lt;%26lt;"Are there any more family members?(Y for yes and N for no)";


cin%26gt;%26gt;choice;


}








cout%26lt;%26lt;"Thank you. The ages of your family in reverse order are:"%26lt;%26lt;endl;


/* Change the count%26gt;0 to count%26gt;=0 for it to print out the first entry as well */


while(count%26gt;=0)


{


cout%26lt;%26lt;" "%26lt;%26lt;ageValue[count];





/* Place the count decrement here */


count--;


}





return 0;





}
Reply:I have not had a chance to compile this, so I am not sure it is error-free. But I think that it should work fine.
