# C++ Exercises: Multiply each integer in a list three times

## C++ Basic Algorithm: Exercise-125 with Solution

Write a C++ program that multiplies each integer three times to create a list from a given list of integers.

Test Data:
({1, 2, 3, 4}-> (1 8 27 64}

Sample Solution:

C++ Code :

``````#include <bits/stdc++.h>
#include <list>

using namespace std;

list<int> test(list<int> nums) {
list<int> new_list;
list<int>::iterator it;
for (it = nums.begin(); it != nums.end(); ++it)
{
new_list.push_back(*it * *it * *it);
}
return new_list;
}

display_list(list<int> g)
{
list<int>::iterator it;
for (it = g.begin(); it != g.end(); ++it)
cout << *it << ' ';
cout << '\n';
}

int main() {

list<int> nums = {1,2,3,4,5,6,7,8,9};
cout << "Original list of elements:\n";
display_list(nums);
list<int> result_list;
result_list = test(nums);
cout << "\nNew list from the said list multiplies each integer three times:\n";
display_list(result_list);
return 0;
}
``````

Sample Output:

```Original list of elements:
1 2 3 4 5 6 7 8 9

New list from the said list multiplies each integer three times:
1 8 27 64 125 216 343 512 729

```
