简单来写,仅仅输出该图形:
#include <stdio.h>
int main (void)
{
printf("\t\t*\n");
printf("\t\t*\n");
printf("\t * * \n");
printf("\t * * *\n");
printf("\t\t*\n");
printf("\t * * \n");
printf("\t * * *\n");
printf("\t * * * *\n");
printf("\t * * * * *\n");
printf("\t\t*\n");
printf("\t * * \n");
printf("\t * * *\n");
printf("\t * * * *\n");
printf("\t * * * * *\n");
printf("\t * * * * * *\n");
printf("\t * * * * * * *\n");
printf("\t\t*\n");
printf("\t\t*\n");
printf("\t\t*\n");
printf("\t\t*\n");
printf("\t\t*\n");
}
