include "stdio.h"
include "math.h"
void main()
{
double a,b;
scanf("%f",&a);
b=atan(a);
printf(%f",b);
getch();
}
用Win-TC编译
include "math.h"
void main()
{
double a,b;
scanf("%f",&a);
b=atan(a);
printf(%f",b);
getch();
}
用Win-TC编译
要用%lf
#include "stdio.h"
#include "math.h"
#include "conio.h"
void main()
{
double a,b;
scanf("%lf",&a);
b=atan(a);
printf("%f",b);
getch();
}
