C语言趣味编程（二）

正弦函数与余弦函数

#include <stdio.h>
#include <math.h>

int main()
{
    double y;
    int m,n,p,q,x;

    for(y = 1;y >=0;y -= 0.1)
    {
        p = acos(y)*10;
        q = asin(y)*10;
        for(x = 1;x<=62;x ++)
        {
            if(x == p&&x==q)
                printf("+");
            else if(x == p || x == 62 -p)
                printf("+");
            else if(x == q ||x ==31 - q)
                printf("*");
            else
                printf(" ");
        }
        printf("\n");
    }
    for (y = 0;y > -1;y -= 0.1)
    {
        m = acos(y)*10;
        n = (asin(-y) + 3.1)*10;
        for(x = 1;x<=62;x++)
        {
            if(x == m&&x==n)
                printf("+");
            else if(x == m || x == 62 -m)
                printf("+");
            else if(x == n ||x == 93 - n)
                printf("*");
            else
            printf(" ");
        }
        printf ("\n");
    }
    return 0;
}

运行结果如下
