Uses library features to line up the table columns and rows

Answer 1

CODE IN C++:

#include <iostream>

using namespace std;

int main()
{
int n ;
cout << "Enter an integer(1-20) : ";
cin >> n ;
while( n < 1 || n > 20){
cout << "Reenter an integer(1-20) : ";
cin >> n ;
}
  
cout << "Multiplication table of " << n << endl ;
for(int i = 1; i <= 10; i++)
cout << n << " * " << i << " = " << n * i << endl ;

return 0;
}

OUTPUT:
