14. write an if/then/else primitive to do each of the following operations: a. compute and display the value x ÷ y if the value of y is not 0. if y does have the value 0, then display the message ‘unable to perform the division’. b. compute the area and circumference of a circle given the radius r if the radius is greater than or equal to 1.0; otherwise, you should compute only the circumference.

// part (a).

//include header

#include <bits/stdc++.h>

using namespace std;

//main function

int main() {

// variables

int x_val,y_val;

cout<<"enter value of x:";

// read the value of x

cin>>x_val;

cout<<"enter value of y:";

// read the value of y

cin>>y_val;

// check if y=0 or not

if(y_val==0)

cout<<"Unable to perform the division"<<endl;

else

cout<<"value of x/y is: "<<x_val/y_val<<endl;

return 0;

}

Explanation:

Declare variable "x","y" and read the value of both from user.If value of "y" is equal to 0 then it will print "Unable to perform the division" else it will calculate x/y and print its value.

Output:

enter value of x:4

enter value of y:0

Unable to perform the division

enter value of x:5

enter value of y:2

value of x/y is: 2

//part(b)

//include header

#include <bits/stdc++.h>

using namespace std;

//main function

int main() {

// variable to store radius of circle

float cir_rad;

cout<<"enter the radius :";

// read the radius of circle

cin>>cir_rad;

// validate the radius, it must be positive

while(cir_rad<=0)

{

   cout<<"radius must be positive:";

   cin>>cir_rad;

}

// if radius is greater or equal to 1 Then

// it will calculate area and circumference and print

if(cir_rad>=1)

{

   float area=3.14*cir_rad*cir_rad;

   cout<<"area of circle is: "<<area<<endl;

   float circumference=2*3.14*cir_rad;

   cout<<"circumference of circle is: "<<circumference<<endl;

}

// else it will only circumference and print

else{

    float circumference=2*3.14*cir_rad;

   cout<<"circumference of circle is: "<<circumference<<endl;

}

return 0;

}

Explanation:

Read the value of radius from user and Assign it to variable "r".Check if "r" is negative or not.If "r" is negative then again ask user to enter a positive radius. After that if radius is greater or equal to 1 then it will Calculate area and circumference of circle and print.If radius is less than 1 then it will Calculate only circumference and print.

Output:

enter the radius:-2

radius must be positive:2

area of circle is: 12.56

circumference of circle is: 12.56

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
