Answer:
The second is that laughter prepares us for tough conditions. And it does always ensure good things for us, and there are many real advantages of the laughter that we can trace out. And all those can be parsed from our real life. We just need to think of a sad situation and try to realize how laughter helps us get rid of that sad situation. And that is what is the central idea of the second section.

Answer:
# include<math.h>
# include<stdlib.h>
# include<stdio.h>
int main()
{
int choice;
double area;
printf("Enter the area of Square:");
scanf("%lf", &area);
printf("Enter the choice: 1, 2:");
scanf("%d", &choice);
switch(choice)
{
case 1:if(area<0.00)
{
printf(" INVALID");
break;
}
else
{
printf("side of square: %lf", sqrt(area));
break;
}
break;
case 2: break;
}
return 0;
}
Explanation:
Here, if area is less than 0 then invalid message is printed out. And if area is more than 0 then the sqrt is calculated and the side of a square length is being printed out. And that is what is required. lf is for double. And math.h is included to make use of the sqrt function.
