How to implement rose code in C language

C language rose code implementation method: 1. Use two nested loops to traverse each position of the flower. The first loop variable i is used to control the number of rows, and the second loop variable j is used To control the number of columns; 2. Calculate the distance from the current position i and j to the center point to determine the character that should be drawn at the current position. If the distance is less than or equal to "n*n/4", we draw the * character; if the distance is less than or equal to "n *n/2", we draw the . character, otherwise, we draw the space character; 3. By appropriately adjusting the value of the variable n, the size of the flower can be changed.

To implement the C language rose code, we can use loops and conditional statements to draw the shape of the flower. The following is a simple C language code example that can draw a rose shape.

#include <stdio.h>
int main() {
    int n = 20;  // 花朵的大小，可以根据需要调整
    for (int i = -n; i <= n; i++) {
        for (int j = -n; j <= n; j++) {
            // 计算当前位置到中心点的距离
            double distance = i * i + j * j;
            // 根据距离来确定当前位置应该绘制的字符
            if (distance <= n * n / 4) {
                printf("*");
            } else if (distance <= n * n / 2) {
                printf(".");
            } else {
                printf(" ");
            }
        }
        printf("\n");
    }
    
    return 0;
}

In this code example, we use two nested loops to iterate through each position of the flower. The first loop variable i is used to control the number of rows, and the second loop variable j is used to control the number of columns.

We determine the character that should be drawn at the current position by calculating the distance from the current position i and j to the center point. If the distance is less than or equal to n * n / 4, we draw the * character; if the distance is less than or equal to n * n / 2, we draw the . character; otherwise, we draw the space character.

The size of the flower can be changed by appropriately adjusting the value of the variable n. In the above code, we set n to 20. You can try using other values ​​to get different sizes of rose shapes.
