在C语言中,可以使用循环嵌套来实现菱形打印。下面是一个示例代码:
#include <stdio.h> int main() { int n, c, k, space = 1; printf("Enter number of rows: "); scanf("%d", &n); space = n - 1; for (k = 1; k <= n; k++) { for (c = 1; c <= space; c++) printf(" "); space--; for (c = 1; c <= 2*k-1; c++) printf("*"); printf("\n"); } space = 1; for (k = 1; k <= n - 1; k++) { for (c = 1; c <= space; c++) printf(" "); space++; for (c = 1 ; c <= 2*(n-k)-1; c++) printf("*"); printf("\n"); } return 0; }
此代码段将会打印出一个菱形形状,根据用户输入的行数。用户输入的行数决定了菱形的大小。
