C语言上下金字塔
用上一道金字塔题来思考
#include <stdio.h>
int main()
{
int n = 0;
while (scanf("%d", &n)!=EOF)
{
for (int i = 1; i <= n; i++)
{
for (int j = 1; j <= n - i; j++)
{
printf(" ");
}
for (int k = 1; k <= 2 * i - 1; k++)
{
printf("*");
}
printf("\n");
}
for (int i = 2; i <= n; i++)
{
for (int k = 1; k <=i-1; k++)
{
printf(" ");
}
for (int j = 1; j <=2*n-(2*i-1); j++)
{
printf("*");
}
printf("\n");
}
}
}
）。
