昨天写了一个代码使用C语言画三角形既然写了那个那就继续画一条直线这个也很有意思。C语言不调用库函数画一个三角形直线的方程是如下图所示— — 斜率的范围(-∞,∞)既然知道公式了我们就直接上代码吧之前有人评论说 putchar函数可以修改下这次我们就修改下。还有我这次就不用浮点型了直接用int来做计算。#include stdio.htypedef struct {int x,y; } Vec; /*ykxb*/ int judge(Vec p,int k,int b){int tmp p.y - k*p.x -b;if(tmp 0)return 1;return 0; }int main(){Vec p;int k 1;int b 16;for(p.y 50;p.y -50;p.y -2,putchar(\n))for(p.x -50;p.x 50;p.x)putchar(judge(p,k,b)?:.); }用图片来更直观的来感受下输出如果坐标系更大就会更细腻—— 程序输出weiqifabsp-ubuntu1804:~/c$ gcc elsfk.c ./a.out
