Question

Help needed in c program ! Thannx

Write a C code to calculate the following piecewise function using switch. Assume user enters x (a real number) tan(x +1) 10 f(x) =,x = 0 x <0

Answer 1

#include <stdio.h>
#include<math.h>

int main()
{ float x;
float value;
int y;
printf("enter x values\n");
scanf("%f",&x);
if(x>0)
y=1;
else if(x==0)
y=2;
else
y=3;
switch(y){
case 1:
value=tan(x+1) ;

printf("function f(x) is %.3f\n",value);
break;
case 2:
value=10;
printf("function f(x) is %.3f\n",value);
break;
case 3:
value=pow(x-1,1/3)-pow(x+5,1/5);
printf("function f(x) is %.3f\n",value);
break;
default:
printf("yo have entered an improper input");
}
return 0;
}

#include #include«math.h> int main() float x; float value; int y: printf("enter x scanf("%f", &x); if(x>0) values \n"); y-1; y 2; y-3; else if(x-0) else switch(y)f case 1: value-tan(x+1) .; printf("function f(x) break is %. 3fin",value); case 2: value-10; printf("function f(x) break is %.3fin",value); case 3: value-pow(x-1,1/3)-pow(x+5,1/5); printf("function f(x) is %. 3fin",value); break default: printf("yo have entered an improper input"); return e;

enter x values 1.3 function f(x) is -1.119

enter x values function f(x) is 10.000

enter x values 0.3 function f(x) is 3.602
