怎么用VB编码计算分段函数

#include<stido.h>

int main()

{

   int x,y

   scanf("%d",&x)

   if(0<x&&x<10) y=3*x+2

   else

       {if(x=0) y=0

       else

          {if (x<0) y=x*x

           else printf("go die\n")

         乎卖瞎 }

       }

  printf("%d",y)

  return 0

}

该程序的分段配旅函数如下：

f(x)=3x+2 岁空 (0<x<10)

f(x)=1         (x=0)

 f(x) = x*x    (x<0)

如果输入x值不再取值范围内，打印go die...

学好编程最重要的是自己要思考，要想。不然没有任何进步。

x=val(inputbox("乱敏陵请你输入拿老X的值"哗戚)

if x<0 then

y=1-2*x

else

y=1+x

end if

print y

1,#include<Stdio.h>

int main(){

int x = 0

scanf("%d",&x)

if(x <0)

printf("-1")

else if( x == 0)

printf("0")

else

printf("1")

return 0

}

2,#include<stdio.h>

int main(){

float a,b,c

scanf("%f%f%f",&a,&b,&c)

if(a >b)

a = a+b - (b = a)

if(c <a){

c = a + c -( a = c)

c = b + c - (b = c)

}

if(c <b)

c = c+b - (b = c)

printf("%f %f %f",c,b,a)

return 0

}

3,#include<stdio.h>

int main(){

int a ,b,c

scanf("%d%d%d",&a,&b,&c)

printf("%d",(a>b?a:b)>c?(a>b?a:b):c)

return 0

}

4,#include<stdio.h>嫌樱

int main(){

float r = 0

printf("请输入半径"指者和唯盯)

scanf("%f",&r)

printf("周长是%f",2*3.14*r)

printf("面积是%f",3.14*r*r)

return 0

}

5,#include<stdio.h>

#include<math.h>

int main(){

int x = 0

scanf("%d",&x)

if (x <-10)

printf("%d",5- x)

else if( x <= 10)

printf("%d", 4 * x -8)

else

printf("%d",sqrt(x))

return 0

}
