打印爱心

1.1:普通输出爱心

#include
int main()
{
	printf("       *********         *********\n");   //7（代表边上的空格）
	printf("    ***************   ***************\n"); //4
	printf("  ****************** ******************\n");//2
	printf(" ***************************************\n");//1
	printf("*****************************************\n");//0
	printf("*****************************************\n");//0
	printf(" ***************************************\n");//1
	printf("  *************************************\n");//2
	printf("   **********************************\n");//4
	printf("      *****************************\n");//6
	printf("        *************************\n");//8
	printf("           *******************\n");//11
	printf("              *************\n");//14
	printf("                 *******\n");//17
	printf("                   ***\n");//19
	return 0;
}

1.2循环打印爱心（效果自己实现观看）

#include
int main()
{
	int gui[15] = { 7,4,2,1,0,0,1,2,4,6,8,11,14,17,19 };// 输出每一行的空格数
	int i = 0,j=0;
	int zhonggui[3] = { 9,3,1 }; //输出中间的空格
	int xing[3] = { 9,15,18 };  //输出中间的星号
	for (i = 0; i < 3; i++)
	{
		for (j = 0; j < gui[i]; j++)       putchar(' ');
		for (j = 0; j < xing[i]; j++)      putchar('*');
		for (j = 0; j < zhonggui[i]; j++) putchar(' ');
		for (j = 0; j < xing[i]; j++)      putchar('*');
		putchar('\n');
	}
 
	for (i = 3; i <15; i++)
	{
		for (j = 0; j < gui[i]; j++)		   putchar(' ');
		for (j = 0; j < 41 - gui[i] * 2; j++)  putchar('*');
		putchar('\n');
	}
	getchar();
	return 0;
}

2：符号变换爱心（这个还是不错的，有动态效果的样子）

#include
#include
#include
#include
char str[15][41] = {
	"       *********         *********       ",
	"    ***************   ***************    ",
	"  ****************** ******************  ",
	" *************************************** ",
	"*****************************************",
	"*****************************************",
	" *************************************** ",
	"  *************************************  ",
	"    *********************************    ",
	"      *****************************      ",
	"        *************************        ",
	"           *******************           ",
	"              *************              ",
	"                 *******                 ",
	"                   ***                   ",
 
};
 
void Goto(int hang,int lie)
{
	COORD cd = {lie,hang};
	SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE), cd);
}
 
void Dong(int m,char c)
{
	int n = 0;
	while (n++ < 1000)
	{
		int hang = rand() % 15;
		int lie = rand() % 41;
		if ('*' != str[hang][lie])
			continue;
 
		Goto(hang, lie);
		putchar(c);
		 Sleep(5);
	}
 
}
 
int main()
{
	srand((unsigned int)time(NULL));
	Dong(300, '*');
	Dong(500, '+');
	Dong(200, '+');
	return 0;
}
