C语言绘制三角函数曲线

#include <stdio.h>
#include <math.h>
 
int main()
{
 int x;
 double y;
 int m;
 int i;
 
 for (y = 1; y >= -1; y = y - 0.1)
 {
  x = acos(y) * 10;
 m = 62 - x;
 
 for (i = 0; i < x; i++)
 {
  printf(" ");
 }
 
 printf("*");
 
 for (i = x; i < m; i++)
 {
  printf(" ");
 }
 
 printf("*\n");
 }
 
 return 0;
}

//用“*”显示0～360的sin(x)的曲线
