请随便编一个小程序 谢谢

#include "stdio.h"
#include "math.h"
main()
{
double i;
double x;
printf("Please input x:");
scanf("%lf",&x);
i=sin(x);//here x is radian
printf("%lf",i);
}

要的是从键盘输入度数 EG：sin(30)=0.5;请在看看

试试我这个！
#include <stdio.h>
#include <math.h>
#define EX 0.000001
#define PI 3.14159265
int main()
{
    double x=0.0, temp=1.0, sin=0.0;
    int i;
   
    printf("Please input a degree:");
    scanf("%lf",&x);
    x=x*PI/180;
    temp=x;
    i=0 ;
    while ( fabs(temp) >EX )
    {
        sin += temp;
        i += 2;
        temp = (-1) * temp*x*x/( (i+1)*(i) );
    }
   
    printf("sin(%lf) = %lf ",x,sin);
    printf("The number is %d ",i);
    return 0;
}

good 给分了
