# [c++] Find largest and smallest number in an array

Consider:

``````#include <iostream> // Include header file

using namespace std;

int main () //start of main function
{

int values[20]; // Declares array and how many elements
int small, big; // Declares integer
big = small = values[0]; // Assigns element to be highest or lowest value

for (int i = 0; i < 20; i++) // Counts to 20 and prompts the user for a value and stores it
{
cout << "Enter value " << i << ": ";
cin >> values[i];
}

for (int i = 0; i < 20; i++) // Works out the biggest number
{
if(values[i] > big) // Compare biggest value with current element
{
big = values[i];
}
}

for (int i = 0; i < 20; i++) // Works out the smallest number
{
if (values[i] < small) // Compares smallest value with current element
{
small = values[i];
}
}

cout << "The biggest number is " << big << endl; // Prints outs the biggest number
cout << "The smallest number is " << small << endl; // Prints out the smallest number
}
``````

This is my code so far. The problem I am having is with it printing out the biggest number of the array. Something to do with assigning the first element to the highest and lowest value. It works if I do them separately. Any suggestions?
