how to create multiplication table using 'while' with input number

Question

how can u create multiplication table by inputting any number and get its multiplication table .
ex. int no =2
while(no<22){
cout<<number <<no <<endl;
no+=2
}
output 2 ,4,6,8...,20
so how can i take any value as 'no' and create its multiplication table ?

Answer 1

Would be shorter with a for loop.

int n; cin >> n;
for (int i = 0; i < 22; i++)
cout << n << "*" << i << " = " << n*i << endl;

// which is the equivalent of

int n, i = 0; cin >> n;
while (i < 22) {
cout << n << "*" << i << " = " << n*i << endl;
i++;
}

// ... doesn't really look like much of a difference now, does it.

Answer 2

Replace 'int no=3' with 'no = Input()', the user will then define 'no'
