One 、 Realization effect

Print the five pointed star as shown in the figure

First, build a two-dimensional array , Divide the five pointed star into four parts from top to bottom , Use different for The loop statement fills a two-dimensional array * To build the completed Pentagram

Two 、 Complete code

#include <stdio.h>
char wj[15][38];
int main()
{
	int i=0, j=0, k, m4, n4;
	for (int i = 0; i < 5; i++)                    // This is the upper corner of the pentagram (4 That's ok ）
	{
		for (int j = 0; j < 18 - i; j++)// Find rules and read spaces in the array 
			wj[i][j] = ' ';
		for (j = 18-i; j <=  i + 18; j++)// Find rules and read them in the array *
			wj[i][j] = '*';

	}
	for (i = 5; i < 9; i++)                    // These are the middle two corners of the pentagram （4 That's ok ）
	{
		for (j = 0; j < 3 * i - 15; j++)
			wj[i][j] = ' ';
		for (j = 3 * i - 15; j <= 51 - 3 * i; j++)
			wj[i][j] = '*';
	}

	for (i = 9; i < 11; i++) // This is the part where the middle meets the lower part （2 That's ok ）
	{
		for (j = 0; j < 20 - i; j++)
			wj[i][j] = ' ';
		for (j = 20 - i; j <= 15 + i; j++)
			wj[i][j] = '*';
	}

	for (i = 11; i < 15; i++) // These are the lower two corners of the pentagram （4 That's ok ）
	{
		for (j = 0; j < 20 - i; j++)
			wj[i][j] = ' ';
		for (j = 20 - i; j <= 49 - 3 * i; j++)
			wj[i][j] = '*';
		for (j = 50 - 3 * i; j < 3 * i - 14; j++)// The space between the lower two corners 
			wj[i][j] = ' ';
		for (j = 3 * i - 14; j < i + 16; j++)
			wj[i][j] = '*';
	}

	for (i = 0; i < 15; i++)// Loop out the entire two-dimensional character array 
	{
		for (j = 0; j < 38; j++)
			printf("%c", wj[i][j]);
		printf("\n");
	}
}
