help me with the modification of the code

[Zaneemma]

#include <iostream>
using namespace std;
int main()

{
int arraySize;

cout<<"How many integers are you inputing? ";
cin>>arraySize;

int a,b;
cout<<"Input the range [a,b]? ";
cin>>a>>b;

cout<<"a= "<<a<<endl;
cout <<"b= "<<b<<endl;
if (arraySize>0)
{
if(a>b)
{
int temp1=a;
a=b;
b=temp1;
}

int *arrayName=new int [arraySize] {};
srand(time(nullptr));

for(int i=0; i<arraySize; ++i)
{
arrayName[i]=rand()%(b-a+1)+a;
}
cout<<"\nNumbers from the range"<<"["<<a<<","<<b<<"]\n";
for(int i=0; i<arraySize; ++i)
{
cout<<arrayName[i]<<"\t";
}
cout <<endl;


int counter =0;
int sum=0;
double average;

for(int i =0; i<arraySize; ++i)
{
if(arrayName[i]%2!=0)
{
++counter;
sum+=arrayName[i];
}
else
{
cout<<"The number is an even number"<<endl;
break;
}
}
average=sum/counter;
cout<< "The total of the odd is: " <<counter <<endl;
cout<< "The total sum of the odd is:" <<sum <<endl;
cout<< "The average numbers are:" <<average <<endl;


return 0;
}
}

What modification do you need help with?

The only problem I see is that the use of time() on line 27 requires the <ctime> header.

PLEASE ALWAYS USE CODE TAGS (the <> formatting button) when posting code.
It makes it easier to read your code and also easier to respond to your post.

the modification of the code

You don't say what modification - but consider these modifications:

#include <iostream>
#include <utility>
#include <random>
using namespace std;

auto Rand {mt19937 {random_device {}()}};

int main() {
	size_t arraySize {};

	cout << "How many integers are you inputting? ";
	cin >> arraySize;

	if (arraySize > 0) {
		int a {}, b {};

		cout << "Input the range [a, b]? ";
		cin >> a >> b;

		if (a > b)
			swap(a, b);

		cout << "a = " << a << "\nb = " << b << '\n';

		auto randNo {std::uniform_int_distribution<int> {a, b}};
		size_t counter {};
		double sum {};

		for (size_t i = 0; i < arraySize; ++i) {
			const auto n {randNo(Rand)};

			cout << n << "\t";

			if (n % 2) {
				++counter;
				sum += n;
			}
		}

		const double average {sum / counter};

		cout << "\nThe number of odd is: " << counter << endl;
		cout << "The total sum of odd is: " << sum << endl;
		cout << "The average of odd numbers is: " << average << endl;
	}
}

How many integers are you inputting? 10
Input the range [a, b]? 5 25
a = 5
b = 25
14      23      21      5       17      18      16      16      16      9
The number of odd is: 5
The total sum of odd is: 75
The average of odd numbers is: 15
