C语言：打印菱形(作业考试学习必备系列007)

用C语言在屏幕上输出以下图案：

#define _CRT_SECURE_NO_WARNINGS #include <stdio.h> void chongzhi(char arr[13]) { int a = 0; for (a = 0;a <= 12;a++) { arr[a] = ' '; } } void dayin(char arr[13]) { int a = 0; for (a = 0;a <= 12;a++) { printf("%c", arr[a]); } printf("\n"); } int main() { int a = 0; int b = 0; char arr[13] = { ' ' }; chongzhi(arr); while(a<=12) { if (a <= 6) { int b = 6; int c = 6; int d = 6; while (d <= 12) { arr[b] = '*'; arr[c] = '*'; arr[d] = '*'; dayin(arr); a++; c--; d++; } } else { int e = 0; int f = 12; while (e != f) { arr[e] = ' '; arr[f] = ' '; dayin(arr); a++; e++; f--; } } } return 0; }

运行结果：
