Question

Given: f(x) =-2x6-1.5x4 + 10x + 2 Use a root location technique to determine the maximum of this function. Perform iterations until the approximate relative error falls below 5%. If you use a bracketing method, use initial guesses of xi 0 and xu. If you use the Newton-Raphson, use an initial guess of xi 1. If you use the secant method, use an initial guesses of xi-1 0 and Xi. Assuming that convergence is not an issue, choose the technique that is best suited to this problem. Justify your choice.

Explanation / Answer

ANSWER:

#include <stdio.h>

struct student

{
  
char name[50];
  
int Age;
  
char Country_Name[20];
  
char City_Name[20];
  
float Height;
  
float Weight;
  
char Education[20];

} s[8];

void getAverage(float,float);

void Increase(float,float);

int main()

{
  
int i;
  
printf("Enter information of students: ");
  
for(i=0; i<8; ++i)
  
{

  
printf("Enter name: ");
  
scanf("%s",s[i].name);

  

printf("Enter Age: ");
  
scanf("%d",&s[i].Age);
  
  

printf("Enter Country Name: ");
  
scanf("%s",s[i].Country_Name);
  
  

printf("Enter the City Name: ");
  
scanf("%s",s[i].City_Name);
  
  

printf("Enter the Height: ");
  
scanf("%f",&s[i].Height);
  
  

printf("Enter the Weight: ");
  
scanf("%f",&s[i].Weight);
  
  

printf("Enter the education : ");
  
scanf("%s",s[i].Education);

  

printf(" ");
  
}

  
printf("Displaying Information: ");
  
for(i=0; i<8; ++i)
  
{
  
printf("Name: ");
  
puts(s[i].name);
  
printf("Age: %d ",s[i].Age);
  
printf("Country Name: ");
  
puts(s[i].Country_Name);
  
printf("City Name: ");
  
puts(s[i].City_Name);
  
printf("Height: %.1f ",s[i].Height);
  
printf("Weight: %.1f ",s[i].Weight);
  
printf("Education: ");
  
puts(s[i].Education);
  
printf(" ");

  
}

getAverage(s[i].Height,s[i].Weight);

Increase(s[0].Height,s[0].Weight);
  
  
return 0;

}

void getAverage(float x,float y)

{

int i,total=0,sum=0;

for(i=0;i<8;i++)

{

total += s[i].Weight;

x = total/8;

sum += s[i].Height;

y = sum/8;

}

printf("The average Weight is %.2f ",x);

printf("The average Height is %.2f ",y);

}

void Increase(float x1,float y1)

{

x1 =(s[0].Weight/5)+(s[0].Weight);

y1 =(s[0].Height/5)+(s[0].Height);

printf("The new weight of person 1: %.2f ",x1);

printf("The new height of person 1: %.2f",y1);

}
