使用C语言输出如下图像
思路：确定每行开始位置，和该行’*’的总个数。
代码文件，该图形可以整体右移，请调节 #define LEFT 1 参数
[lhf@localhost work]$ cat diamond.c
/**
* *
* * *
* * * *
* * *
* *
*/
#include <stdio.h>
#define LEFT 1 // right shift space
int main(void)
{
int size = 0;
printf("Input side number of diamond: ");
scanf("%d", &size);
int len = size * 2 - 1;
int high = len;
int width = len + LEFT;
char diamond[high][width];
const char dia = '*';
const char pidd = ' ';
// begin of start and number of diamond
int begin = 0, n;
for (int i = 0; i < high; i++) {
if (i < size) {
begin = size - i - 1 + LEFT;
n = i + 1;
} else {
begin = i - size + 1;
n = size - begin;
begin += LEFT;
}
for (int j = 0; j < width; j++) {
if ((j == begin) && (n--)) {
putchar(dia);
begin += 2;
} else
putchar(pidd);
}
putchar('\n');
}
return 0;
}
