In your world, it is not that a little romantic program apes do not understand? Well, not exactly, program ape world is very romantic drops.
Fool version

Advanced Edition
// Version a: single character heart-shaped pattern #include <stdio.h> int main ( void ) { a float A, X, Y; for (Y = 1.5F ; Y> - 1.5F ; Y- = 0.1f ) { for (X = - 1.5F ; X < 1.5F ; = X + 0.05f ) { a = X * Y * X + Y- . 1 ; // where the @ sign is the heart-shaped pattern printed symbols, Flexible char CH = AX * A * A * X * Y * Y * Y <= 0.0f ? ' @ ' : ' ' the putchar (CH); ; //或者putchar(a*a*a-x*x*y*y*y<=0.0f?'*':' '); } printf("\n"); } return 0; }
//空心版 #include <stdio.h> #include <math.h> // The first heart shape in hollow // (x^2+y^2-1)^3 - x^2*y^3 = 0 // y ~ (-1.1 , 1.3 ) // x ~ (-1.2 , 1.2 ) int main() { for (float y = 1.3; y >= -1.1; y -= 0.06) { for (float x = -1.2; x <= 1.2; x += 0.025) { if (pow((x * x + y * y - 1.0), 3) - x * x * y * y * y <= 0.0) printf(" "); else printf("*"); } printf("\n"); } return 0; }
//版本二：可用多个字符组成打印 #include <stdio.h> int main(void) { float f, x, y, z; for (y = 1.5f; y > -1.5f; y -= 0.1f) { for (x = -1.5f; x < 1.5f; x += 0.05f) { z = x * x + y * y - 1; f = z * z * z - x * x * y * y * y; putchar(f <= 0.0f ? "lihuan"[(int)(f * -8.0f)] : ' '); //这里的lihuan字符可更改成符号或其他字母，汉字不行，图案会变形 } printf("\n"); } return 0; }
//加颜色版
#include <stdio.h> int main(int argc, char* argv[]) { float f, x, y, z; for (y = 1.5f; y > -1.5f; y -= 0.1f) { for (x = -1.5f; x < 1.5f; x += 0.05f) { z = x * x + y * y - 1; f = z * z * z - x * x * y * y * y; // =================================== printf("\033[47m"); char buf[100] = { "lihuan" };
//这里的“lihuan”可以改为其他字符，注意，中文不行哦！ if (f <= 0.0f) { printf("\033[1;31m%c\033[0m", buf[(int)(f * -8.0f)]); } else { printf("%c", ' '); } printf("\033[0m"); // ===================================== } printf("\n"); } return 0; }
加强版：
#include <stdio.h> #include <math.h> float f(float x, float y, float z) { float a = x*x + 9.0f/4.0f*y*y + z*z - 1; return a*a*a - x*x*z*z*z - 9.0f/80.0f*y*y*z*z*z; } float h(float x, float z) { for (float y = 1.0f; y >= 0.0f; y -= 0.001f) { if (f(x, y, z) <= 0.0f) return y; } return 0.0f; } int main(int argc, char *argv[]) { for (float z = 1.5f; z > -1.5f; z -= 0.05f) { for (float x = -1.5f; x < 1.5f; x += 0.025f) { float v = f(x, 0.0f, z); if (v <= 0.0f) { float y0 = h(x, z); float ny = 0.01f; float nx = h(x + ny, z) - y0; float nz = h(x, z + ny) - y0; float nd = 1.0f / sqrtf(nx*nx + ny*ny + nz*nz); float d = (nx + ny - nz)*nd*0.5f + 0.5f; putchar(".:-=+*#%@"[(int)(d * 5.0f)]); } else putchar(' '); } putchar('\n'); } }
变形版：
#include <stdio.h> int main() { int i, j, k, l, m; char c = '*'; //ASCII码里面 3 就是一个字符小爱心 for (i=1; i<=5; i++) printf("\n"); //开头空出5行 for (i=1; i<=3; i++) { //前3行中间有空隙分开来写 for (j=1; j<=32-2*i; j++) printf(" "); //左边的空格，每下一行左边的空格比上一行少2个 //8*n-2*i for (k=1; k<=4*i+1; k++) printf("%c", c);//输出左半部分字符小爱心 for (l=1; l<=13-4*i; l++) printf(" "); //中间的空格，每下一行的空格比上一行少4个 for (m=1; m<=4*i+1; m++) printf("%c", c);//输出右半部分字符小爱心 printf("\n"); //每一行输出完毕换行 } for (i=1; i<=3; i++) { //下3行中间没有空格 for (j=1; j<=24+1; j++) printf(" "); //左边的空格 //8*(n-1)+1 for (k=1; k<=29; k++) printf("%c", c);//输出字符小爱心 printf("\n"); //每一行输出完毕换行 } for (i=7; i>=1; i--) { //下7行 for (j=1; j<=40-2*i; j++) printf(" "); //左边的空格，每下一行左边的空格比上一行少2个//8*(n+1)-2*i for (k=1; k<=4*i-1; k++) printf("%c", c);//每下一行的字符小爱心比上一行少4个（这个循环是i--） printf("\n"); //每一行输出完毕换行 } for (i=1; i<=39; i++) printf(" "); //最后一行左边的空格 printf("%c\n", c); //最后一个字符小爱心 for (i=1; i<=5; i++) printf("\n"); //最后空出5行 return 0; }
