#include<math.h>
#define Pi 3.1415926 
using namespace std;
int main(){
    int i,sinx,cosx;
    int line=0;//行数
    float x=0;
    for(;line<25;x+=Pi/12,line++){         //行间循环
    sinx=39+int(38*sin(x));
    cosx=39+int(38*cos(x));
    for(i=0;i<80;i++){                           //行内循环
        if(i == sinx ) cout<<‘s‘;            //优先输出sinx
           else if(i == cosx) cout<<‘c‘;   //其次输出cosx
                 else if(i == 39) cout<<‘|‘; //最后y轴
         else cout<<‘ ‘;                          //其余空格
    }       //end of 行内
    cout<<endl;    //换行
    }    //end of 行间
    return 0;
