Restriction

[tatay9]

hi guys, i have just one simple doubt i hope you can clear for me, i have a restriction here, and it goes through the whole vector verifying if there is a null value

#include <iostream>
using namespace std;
int main() {
char number[20];
bool isNumber;
do{
isNumber = true;
cout<<"enter your number: ";
cin>>number;
for(int i = 0; number[i] != '\0'; i++){
if(!isdigit(number[i])){
isNumber = false;
cout<<"\nYour Number is Invalid\n";
break;
}
}
}while(!isNumber);
cout<<"\nThe Number you entered is: "<<numero;
cin.get();
return 0;
}

but if i enter for example '3 e', like that with the space, it stops, takes the 3 and adds the e to the next thing i enter. so usually then it crashes when the next variable i'm going to enter is an int.
i don't know if i explained myself perfectly jaja, i would appreciate if you help me.

cin >> doesn't read spaces, use getline instead :

cin.getline( number, 20, '\n' );
// http://www.cplusplus.com/reference/istream/istream/getline/?kw=cin.getline 

and why would you need spaces ? numbers doesn't have spaces ?

~~~~~~~~~

Also i recommend to use std::string instead of fixed sized char array, but you have to use getline( cin, number ) instead and change number declaration to string number;

and #include <string>
