Question

Exercise 1: Write a C++ program that computes the sum of even numbers less than or equal to n where n is given by the user. Exercise 2: What is the output of the following codes? #include <iostream> using namespace std; int main() { int n = 4; int i = 1; int c = 0; while (i < n) { if (i % 2 == 0) { i += 2; } else { --i; } c++; } cout << "c = " << c << endl; cout << "i = " << i << endl; }

          Exercise 1: Write a C++ program that computes the sum of
even numbers less than or equal to n where n is given by
the user.
Exercise 2:
What is the output of the following codes? #include
<iostream> using namespace std;
int main() {
int n = 4; int i = 1; int c = 0;
while (i < n) {
if (i % 2 == 0) { i += 2; }
else { --i; } c++; }
cout << "c = " << c << endl; cout << "i = " << i << endl; }

Step 1

If it is, we add it to a running sum. Finally, we output the sum. Here's the code: ```cpp #include <iostream> using namespace std; int main() { int n; cout << "Enter a number: "; cin >> n; int sum = 0; for (int i = 1; i <= n; i++) { Show more…
