[Solved] Accepting only numbers in C++ program without the if else statement

by


You have inverted the sense of your test. Your for loop can be written as this while loop:

while (verifyPoll >> pollVote && verifyPoll.eof()) {
    // ...
}

What you want is

while (!(verifyPoll >> pollVote && verifyPoll.eof())) {
}

Also, you must not declare a new verifyPoll within the loop body, because now if the first answer does not validate, the loop will not terminate. You might instead assign a new string using

verifyPoll.str(pollVoteString);

but you should do it after the getline.
