In the short code below, I declared an array of five elements. But I'm getting confused on how to use it in a while loop. My main question is , if the user inputs a userchoice1 value that is less than 1, I want the code to keep looping until the user inputs a number that is not less than 1. But I don't know if the 7th line (userchoice1 [x]++) shows the right way to loop it.

Question

int userchoice1[5];
cin>>userchoice1 [x];
if (userchoice1[x]<1) {
while (userchoice1 [x]<1){
cout<<"Number must not be less than 1" <<endl;
cin>>userchoice1 [x];
userchoice1 [x]++;
}
}

Answer 1

thanks vishal. But I made a little mistake in my post. I have corrected it by also putting the cin statement before the if statement.

And as for the array stuff, this code is a part of a much larger code which really wouldn't be necessary to post the whole thing.

really all I need to know is how to loop it correctly(that is, if I got the last line)

Answer 2

I am not sure why you are using array for a single input but basically:
In your code the if statement will be false before even getting input so you dont need it. While will take care of checking input.

while (input>1) {
cout << "Enter input" << endl;
cin >> input;
++input;
}

while (input>1) means loop until user has inputted more than 1.
Use ++input and not input++ as the later skips one update.
