#include <iostream>
#include <stdlib.h>
#include <ctime>
using namespace std;
void arrGenerate(int *a, int size)
{
srand(time(0));
for (int i = 0; i < size; i++)
a[i] = rand() % 100;
}
void arrPrint(int *a, int size)
{
for(int i=0; i<size; i++)
{
cout<<a[i]<<' ';
}
cout<<endl;
}
void arrIncrement(int *a, int size)
{
for(int i=0; i<size; i++)
{
a[i]++;
}
}
int main(int argc, char** argv)
{
const int N=10;
int arr[N];
arrGenerate(arr, N);
arrPrint(arr, N);
arrIncrement(arr, N);
arrPrint(arr, N);
return 0;
}
