Flowchart of Multiplication table Vertically from 1 to n using for loop

C++ Source Code of Program of Multiplication table Vertically from 1 to n using for loop

Lets us see the Program of Multiplication table showing Vertically from 1 to n by using for loop.

#include<iostream>
using namespace std;
int main()
{
	int j,i,n;
	cout<<"Input upto the table number starting from 1 : ";
	cin>>n;
	cout<<"Multiplication table from 1 to "<<n<<endl;
	for(i=1;i<=10;i++)
	{
		for(j=1;j<=n;j++)
		{
			if(j<=n-1)
			{
				cout<<i<<" X "<<j<<" = "<<j*i;
			}
			else
			{
				cout<<i<<" X "<<j<<" = "<<j*i;
			}
		}
		cout<<endl;
	}
}

Output

Flowchart of first 10 natural numbers using while loop

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

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

Output

The first 10 natural number is :

1 2 3 4 5 6 7 8 9 10

The Sum is : 55
