C++ array input validation.
Hi.
I have a program that reads in 10 numbers in an array function then prints out some output. I need the input to be able to only input numbers and nothing else (characters etc). Here is the code.
Code:
#include<iostream>
#include<iomanip>
using namespace std;
void maximum ( float [], float, float&, float&, int&, int& ); //Function Prototype
int main()
{
const arraysize = 10;
float num[arraysize], small, big; //Declaration
int p, p1;
for ( int i = 0; i < 10; i++ ){
cout << endl << "Enter number " << i + 1 << " :\t";
cin >> num[i]; //Array input
}
maximum ( num, arraysize, small, big, p, p1 ); //Function call
cout << endl << "Smallest number" << setw(5) << ":" << small << endl;
cout << endl << "Position is" << setw(9) << ":" << p << endl;
cout << endl << "Biggest number" << setw(5) << ":" << big << endl;
cout << endl << "Position is" << setw(8) << ":" << p1 << endl;
return 0;
}
void maximum (float a[], float size, float& small, float& big, int& position, int& position1){
big = a[0];
small = a[1];
for ( int j = 0; j < size; j++ ){ //Conditions
if ( a[j] <= small ){
small = a[j];
position = j + 1;
}
if ( a[j] >= big ){
big = a[j];
position1 = j + 1;
}
}
}
Can u guys help me validate the input so that only numbers are allowed. Or at least let me know where i can find out about it as my C++ knowledge sucks lol.
