{
int n,sum;
sum=0;
n=1;
do
{
cout<<n;
sum=sum+n;
n++;
}
while(n<=10);
cout<<" The sum of the first 10 natural numbers is?"<< sum;
}

#include <iostream>

using namespace std;

int main()

{

int n,sum;

sum=0;

n=1;

{

cout<<n;

sum=sum+n;

n++;

}

C++ program to find the Sum of the 1st ten natural numbers using while loop

Let us see the C++ program to find the Sum of the 1st ten natural numbers with the help of a while loop.

#include <iostream>
using namespace std;
int main()
{
    int  j, sum = 0;
    cout<<"The first 10 natural number are:\n";
    j=1;
    while(j<=10)
    {
    	sum = sum + j;
        cout<<" "<<j;    
        j++;
    }
    cout<<"\nThe Sum is : "<< sum;
}

#include <iostream>

using namespace std;

int main()

{

int j, sum = 0;

cout<<"The first 10 natural number are:\n";

j=1;

while(j<=10)

{

sum = sum + j;

cout<<" "<<j;

j++;

}

cout<<"\nThe Sum is : "<< sum;

}

Output The first 10 natural number are: 1 2 3 4 5 6 7 8 9 10 The sum is: 55

C++ Sum of the 1st ten natural numbers using for loop

#include <iostream>
using namespace std;
int main()
{
    int loop,Sum=0;
    cout << "\n\n Please! Find the first 10 natural numbers:\n";
    cout << " The natural numbers are: \n";
    for (loop = 1; loop <= 10; loop++) 
    {
        cout << loop << " ";
		Sum=Sum+loop;
    }
     cout << "\n The Sum of first 10 natural numbers: "<<Sum << endl;
}

#include <iostream>

using namespace std;

int main()

{

int loop,Sum=0;

cout << "\n\n Please! Find the first 10 natural numbers:\n";

cout << " The natural numbers are: \n";

for (loop = 1; loop <= 10; loop++)

{

cout << loop << " ";

Sum=Sum+loop;

}

cout << "\n The Sum of first 10 natural numbers: "<<Sum << endl;

}

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
