Answer:
To check if the year comes under each 100th year, lets check if the remainder when dividing with 100 is 0 or not.
Similarly check for 400th year and multiple 0f 4. The following C program describes the function.
#include<stdio.h>
#include<stdbool.h>
bool is_leap_year(int year);
void main()
{
int y;
bool b;
printf("Enter the year in yyyy format: e.g. 1999 \n");
scanf("%d", &y); // taking the input year in yyyy format.
b= is_leap_year(y); //calling the function and returning the output to b
if(b==true)
{
printf("Thae given year is a leap year \n");
}
else
{
printf("The given year is not a leap year \n");
}
}
bool is_leap_year(int year)
{
if(year%100==0) //every 100th year
{
if(year%400==0) //every 400th year
{
return true;
}
else
{
return false;
}
}
if(year%4==0) //is a multiple of 4
{
return true;
}
else
{
return false;
}
}

Answer:
i) It is difficult to put the mouse pointer's insertion point in the text
ii) A gray border appear around the time and date when you point to it
Explanation:
When the date and time is pointed to or hovered using the mouse pointer, we have, that the background of the text changes to a grey border around the text when the date and time is inserted as a special object using the insert date and time button on the insert menu in the word processing application
The mouse pointer behaves different when working with some applications, and it could be difficult to place the insertion point of the mouse pointer in the text
Therefore, the correct options are;
<em>It is difficult to put the mouse pointer's insertion point in the text and</em>
<em>A gray border appear around the time and date when you point to it.</em>
