Question

Complete the implementation of the point_3d program. This program will help you learn how to use: the C language if statement; relational operators; and boolean operators. The program must implement a function which maps real-valued point (x,y) to real value z≥0, as follows: z=2.84898x+1.18569y, when x≥0 and y≥0; z=2.84898x+y2, when x≥0 and y<0; z=x2+1.18569y, when x<0 and y≥0; z=x2+y2, otherwise. To get the values of x and y, display a prompt of the form "Please enter X and Y:" The prompt should appear on a line by itself. To display the results, use a message of the form "(X, Y) -> Z." where X and Y are the numeric values entered by the user, and z is the result computed according to equations 1–4. All results should be displayed with 8 decimal places.(In C proragming)

Answer 1

Here is the code below :

#include<stdio.h>

int main(){

    float x, y, z;

    printf("Please enter X and Y: ");

    scanf("%f %f", &x, &y);

    if((x >= 0) && (y >= 0)){

        z = (2.84898 * x) + (1.18569 * y);

        printf("(%f, %f) -> %.8f.", x, y, z);

    }else if((x >= 0) && (y < 0)){

        

        z = (2.84898 * x) + (2 * y);

        printf("(%f, %f) -> %.8f.", x, y, z);

    }else if((x < 0) && (y >=0 )){

        

        z = (x * 2) + (1.18569 * y);

        printf("(%f, %f) -> %.8f.", x, y, z);

    }else{

        z = (2 * x) + (2 * y);

        printf("(%f, %f) -> %.8f.", x, y, z);

    }

    return 0;

}

Hope you find the solution good.

Have a Good Day !!
