# C++ Exercises: Find the sum of first 10 natural numbers

## C++ For Loop: Exercise-2 with Solution

Write a program in C++ to find the sum of the first 10 natural numbers.

**Visual Presentation:**

**Sample Solution** :-

**C++ Code :**

```
#include <iostream> // Preprocessor directive to include the input/output stream header file
using namespace std; // Using the standard namespace to avoid writing std::
int main() // Start of the main function
{
int i, sum = 0; // Declare integer variables 'i' and 'sum' and initialize 'sum' to 0
cout << "\n\n Find the first 10 natural numbers:\n"; // Display a message to find the first 10 natural numbers
cout << "---------------------------------------\n"; // Display a separator line
cout << " The natural numbers are: \n"; // Display a message indicating the list of natural numbers
// Loop to print the first 10 natural numbers and calculate their sum
for (i = 1; i <= 10; i++)
{
cout << i << " "; // Output each natural number followed by a space
sum = sum + i; // Calculate the sum by adding the current number 'i' to 'sum'
}
cout << "\n The sum of first 10 natural numbers: " << sum << endl; // Display the sum of the first 10 natural numbers
}
```

Sample Output:

Find the first 10 natural numbers: --------------------------------------- The natural numbers are: 1 2 3 4 5 6 7 8 9 10 The sum of first 10 natural numbers: 55
