用c语言求分段函数#includestdio.h
int main()
{
float x,y;
scanf("%f",x);
if(x1)
{
y=x*x;
}
else if(x=1x=10)
{
y=2*x-1;
}
else
y=3*x-11;
printf("x=%f,y=%f\n",x,y);
return 0;
}
用c语言程序 求分段函数，求解！#include stdio.h
int main(void){
double x;
printf("Input x(R:)...\nx=");
scanf("%lf",x);
printf("y = %f\n",(x-1.0x1.0) ? x 1 : x-1);
return 0;
}
用C语言计算分段函数#include "stdio.h"
#includemath.h
void main()
【c语言求分段函数0 c语言求分段函数sign】{
double x,y,f,h;
printf("请输入x:\n");
scanf("%lf",x);
printf("请输入y:\n");
scanf("%lf",y);
if((x=0)(y0))
f=2*pow(x,2) 3*x 1/x y;
else if((x=0)(y=0))
f=2*x*x 3*x 1/x y*y;
else
f=3*sin(x y)/2/pow(x,2) 3*x 1;
printf("x=%lf,y=%lf,f=%lf\n",x,y,f);
h=pow(x,2);
printf("%lf",h);
}
用C语言求分段函数值#include stdio.h
int main()
{double x,y;
scanf("%lf",x);
if(x0)y=x*x-1;
else if(x1)y=x*x;
else y=x*x 1;
printf("%g",y);
return 0;
}
C语言计算分段函数1. 代码如下c语言求分段函数0，3）需要实际运行时输入测试
int main(void)
{
double x, y, f;
printf("Please input 2 double number in the form of x y:\n");
scanf("%lf%lf", x, y);
if(x=0y0)
f = 2*x*x3*x1/(x y);
else if(x=0y=0)
f = 2*x*x3*x1/(1 y*y);
else
f = 3*sin(x y)/(2*x*x)3*x1;
printf("x=%lf, y=%lf, f(x, y)=%lf\n", x, y, f);
return 0;
}
2.代码如下
#include stdio.h
#includemath.h
int main(void)
{
double x, y, f;
printf("Please input 2 double number in the form of x y:\n");
scanf("%lf%lf", x, y);
if(x=0)
{
if(y0)
f = 2*x*x3*x1/(x y);
else
f = 2*x*x3*x1/(1 y*y);
}
else
f = 3*sin(x y)/(2*x*x)3*x1;
printf("x=%lf, y=%lf, f(x, y)=%lf\n", x, y, f);
return 0;
}
3.代码如下
#include stdio.h
int main(void)
{
int score = 0;
printf("Please input a score between 0-100:\n");
scanf("%d", score);
if(score0 || score100)
printf("Wrong input of score!\n");
else if(score=90score=100)
printf("A\n");
else if(score=80score=89)
printf("B\n");
else if(score=70score=79)
printf("C\n");
else if(score=60score=69)
printf("D\n");
else
printf("E\n");
return 0;
}
