Why can't i start my code for multiplication table from 3*1=3 ?

Question

I wrote a code for multiplication table of 3. However I just won't get 3 * 1 = 3. Why is it?
Here's the code:
#include <iostream>
using namespace std;

int main()
{
cout << "Let's write table of 3 ! \n" ;
int i=1,mult ;
while (i <= 10) {
cout << "3 * " << i << " = " << mult << endl;
i = i+1;
mult = 3*i ;
}

return 0;
}

__________________________
however this code somewhat works ( but I would like to omit 3*0=0 )

#include <iostream>
using namespace std;

int main()
{
cout << "Let's write table of 3 ! \n" ;
int i=0,mult ;
while (i <= 10) {
cout << "3 * " << i << " = " << mult << endl;
i = i+1;
mult = 3*i ;
}

return 0;
}

Answer 1

Just rearrange the statements in while loop to do calculations before printing:

Answer 2

To avoid 0, initialize i with 1

int i=1, mult;

Answer 3

Take input from user u can calculate table of any number see i did little changes

#include <iostream>
using namespace std;

int main()
{
int number;
cout << "Let's write table of " ;
cin>>number;
cout<<endl;
int i=1,mult ;
while (i <= 10) {
cout <<number<< "* " << i << " = " << mult << endl;
i = i+1;
mult = 3*i ;
}

return 0;
}

Thanx a lot

But in the first code I have already done that
