注意事项:

参考代码:

#include<iostream>

using namespace std;

int main()

{

cout << "  " << "Nine-by-nine Multiplication Table" << endl;

cout << "--------------------------------------" << endl;

cout << "     " << "1   2   3   4   5   6   7   8   9" << endl;

cout << "--------------------------------------" << endl;

for(int i = 1;i <= 9;i ++)

{

printf(" %d  ",i);

for(int j = 1;j <= i;j ++)

{

int sum = i*j;

printf("%2d  ",sum);

}

cout << endl;

}

cout << "--------------------------------------" << endl;

return 0;

}
