Question 3: Write a C++ program to:
Declare and initialize an array of 5 integers.
Reverse the elements of the array.
Print the reversed array.
#include <iostream>
using namespace std;
int main() {
// Declare and initialize array
int arr[5] = {1, 2, 3, 4, 5};
// Print original array
cout << "Original Array: ";
for (int i = 0; i < 5; i++) {
cout << arr[i] << " ";
}
cout << endl;
// Reverse array (swap first with last, etc.)
for (int i = 0; i < 5 / 2; i++) {
int temp = arr[i];
arr[i] = arr[5 - i - 1];
arr[5 - i - 1] = temp;
}
// Print reversed array
cout << "Reversed Array: ";
for (int i = 0; i < 5; i++) {
cout << arr[i] << " ";
}
cout << endl;
return 0;
}
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
