用C++编写程序（打印九九乘法表）
#include "stdio.h'
#include "stdlib.h'
int main()
{
int i, j;
for (i = 1; i < 10; i++)
printf("%-2d ", i);
printf("
");
for (i = 1; i < 亮蚂10; i++)
printf("- ");
printf("
");
for (i = 1; i < 10; i++)
{
for (j 辩键含= 1; j < i; j++)
printf(" ");
for (; j < 10; j++)
printf("%-2d ", i 携笑* j);
printf("
");
}
return 0;
