方法一:基于三角形的分割
```c
include
int main() {
int n, c, k, space = 1;
printf("Enter number of rows: ");
scanf("%d", &n);
space = n - 1;
// 上半部分
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");
}
// 下半部分
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;
}
```
方法二:使用二维数组
```c
include
int main() {
int diamond[] = {
{' ', ' ', '*', ' ', ' '},
{' ', '*', ' ', ' ', ' '},
{'*', ' ', ' ', ' ', ' '},
{' ', '*', ' ', ' ', ' '},
{' ', ' ', '*', ' ', ' '}
};
int i, j;
for (i = 0; i < 5; i++) {
for (j = 0; j < 5; j++) {
printf("%c", diamond[i][j]);
}
printf("\n");
}
return 0;
}
```
方法三:通过控制空格和星号输出
```c
include
int main() {
int n;
printf("Enter number of rows: ");
scanf("%d", &n);
// 上半部分
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");
}
// 下半部分
for (int i = n - 1; i >= 1; i--) {
for (int j = 1; j <= n - i; j++) printf(" ");
for (int k = 1; k <= 2 * i - 1; k++) printf("*");
printf("\n");
}
return 0;
}
```
方法四:使用Python实现
```python
n = int(input("请输入菱形的边长: "))
for i in range(n):
for j in range(n - i - 1):
print(" ", end="")
for j in range(i + 1):
print(chr(65 + j), end="")
for j in range(i, 0, -1):
print(chr(64 + j), end="")
print()
for i in range(n - 2, -1, -1):
for j in range(n - i - 1):
print(" ", end="")
for j in range(i + 1):
print(chr(65 + j), end="")
for j in range(i, 0, -1):
print(chr(64 + j), end="")
print()
```
这些方法都可以实现菱形的输出,你可以根据自己的需求和编程环境选择合适的方法。
