Question

Answer in C using basic C and loops.

ASSIGNMENT: Write a program that will display how many times a ball will bounce until its height is less than 1 inch. A ball has a property called the coefficient of restitution, a number between 0.0 and 1.0, that indicates how 'bouncy' the ball is. A coefficient of restitution of .5 means that the ball will bounce-up 50% of its initial height after each bounce Write a program to ask the user to enter the initial height of the ball (in feet) and the coefficient of restitution of the ball, and then display how many times the ball will bounce (until its buonce-up height is less than 1 inch). Validate that the initial height is greater than or equal to zero (0) and that the coefficient of restitution is between 0.0 and 1.0 inclusive. The validation error messages and re-prompts are indented 3 spaces. Create constants for the 2 coefficient of restitution limits, and use the constants in the prompts and the validation condition. Also, create a constant for 1 inch (remember that the program is written for the initial height input in feet). If the coefficient of restitution is 1.0, the ball will never stop bouncing - test for that condition and display an appropriate message. Also, have a singular/plural decision to display "time" or "times" Example Run #1: (bold type is what is entered by the user) Enter the initial height of the ball (in feet): -5 The initial height of the ball must be a positive number. Please re-enter the initial height of the ball (in feet): 5.5 Enter the balls' coefficient of restitution (0.0 to 1.0): 5 The coefficient of restitution must be between 0.0 and 1.0 inclusive. Please re-enter the balls' coefficient of restitution (0.0 to 1.0): .5 The ball bounced x times. Example Run #2: Enter the initial height of the ball (in feet): 5 Enter the balls' coefficient of restitution (0.0 to 1.0): 1 With a coefficient of restitution equal to 1.0, the ball will bounce forever! The example run shows EXACTLY how your program input and output will look.

Answer 1

PROGRAM:

#include <stdio.h>
int main()
{
double height,cor;
printf("Enter the initial height of the ball (in feet) : ");
scanf("%lf",&height);
while(height<0.0)
{
printf(" The initial height of the ball must be a positive number.");
printf("\n Please re-enter the initial height of the ball (in feet) : ");
scanf("%lf",&height);
}
printf("Enter the ball\'s cofficient of restitution (0.0 to 1.0) : ");
scanf("%lf",&cor);
while(cor<0.0 || cor>1.0)
{
printf(" The cofficient of restitution must be between 0.0 and 1.0 inclusive.");
printf("\n Please re-enter the ball\'s cofficient of restitution (0.0 to 1.0) : ");
scanf("%lf",&cor);
}
if(cor>0.0 && cor<1.0)
{
printf("\nThe ball bounced x times.");
}
else if(cor==1.0)
{
printf("\nWith the cofficient of restitution equal to 1.0, the ball will bounce forever!");
}

return 0;
}
