This program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by user specified arrow base height, arrow base width, and arrow head width. #include int main(void) {int arrowBaseHeight = 0;int arrowBaseWidth = 0;int arrowHeadWidth = 0;printf("Enter arrow base height:\n");scanf("%d", &arrowBaseHeight);printf("Enter arrow base width:\n");scanf("%d", &arrowBaseWidth);printf("Enter arrow head width:\n");scanf("%d", &arrowHeadWidth);printf("\n");// Draw arrow base (height = 3, width = 2)printf( "**\n");printf( "**\n");printf( "**\n");// Draw arrow head (width = 4)printf( "****\n");printf( "***\n");printf( "**\n");printf( "*\n");return 0;}a. Modify the given program to use a loop to output an arrow base of height arrow_base_height. b. Modify the given program to use a loop to output an arrow base of width arrow_base_width.c. Modify the given program to use a loop to output an arrow head of width arrow_head_width.

Answer:

Here is the C program:

#include <stdio.h>  //to use input output functions

int main(void) {   //start of main function

 int arrowBaseHeight = 0;  //stores value for arrow base height

int  arrowBaseWidth = 0;  //stores value for arrow base width

 int arrowHeadWidth = 0 ;  //stores value for arrow head width

 int i, j;  //to traverse through the rows and columns

 printf("Enter arrow base height:\n");  //prompts user to enter arrow base height value

 scanf("%d", &arrowBaseHeight);  //reads input value of arrow base height

 printf("Enter arrow base width:\n");  //prompts user to enter arrow base width value

 scanf("%d", &arrowBaseWidth);  //reads input value of arrow base width

 while (arrowHeadWidth <= arrowBaseWidth)  {   //iterates as long as the value of arrowHeadWidth is less than or equals to the value of arrowBaseWidth  

     printf("Enter arrow head width:\n");   //prompts user to enter arrow head width value

     scanf("%d", &arrowHeadWidth);   //reads input value of arrow head width

     printf("\n"); }

 for (i = 0; i < arrowBaseHeight; i++)    {   //iterates through rows

     for (j = 0; j < arrowBaseWidth; j++)  {   //iterates through columns

         printf("*");       }   //prints asterisks

     printf("\n");   }   //prints a new line

 for (i = arrowHeadWidth; i > 0; i--)    {   //loop for input length

     for (j = i; j > 0; j--)        {   //iterates for triangle ( to make arrow head)

         printf("*");       }   //prints asterisks

     printf("\n");   }  } //prints new line

Explanation:

The program asks to enter the height of the arrow base, width of the arrow base and the width of arrow head. When asking to enter the width of the arrow head, a condition is checked that the arrow head width arrowHeadWidth should be less than or equal to width of arrow base arrowBaseWidth. The while loop keeps iterating until the user enters the arrow head width larger than the value of arrow base width.  

The loop is used to output an arrow base of height arrowBaseHeight.

The nested loop is being used which as a whole outputs an arrow base of width arrowBaseWidth. The inner loop draws the stars and forms the base width of the arrow, and the outer loop iterates a number of times equal to the height of the arrow.

The last nested loop is used to output an arrow head of width arrowHeadWidth. The inner loop forms the arrow head and prints the stars needed to form an arrow head.

Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Ex: If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 Note: Small expression differences can yield small floating-point output differences due to computer rounding. Ex: (a + b)/3.0 is the same as a/3.0 + b/3.0 but output may differ slightly. Because our system tests programs by comparing output, please obey the following when writing your expression for this problem. First use the dollars/gallon and miles/gallon values to calculate the dollars/mile. Then use the dollars/mile value to determine the cost per 10, 50, and 400 miles. Note: Real per-mile cost would also include maintenance and depreciation.

Assume that at time 5 no system resources are being used except for the processor and memory. Now consider the following events:
At time 5: P1 executes a command to read from disk unit 3.
At time 15: P5’s time slice expires.
At time 18: P7 executes a command to write to disk unit 3.
At time 20: P3 executes a command to read from disk unit 2.
At time 24: P5 executes a command to write to disk unit 3.
At time 28: P5 is swapped out.
At time 33: An interrupt occurs from disk unit 2: P3’s read is complete.
At time 36: An interrupt occurs from disk unit 3: P1’s read is complete.
At time 38: P8 terminates.
At time 40: An interrupt occurs from disk unit 3: P5’s write is complete.
At time 44: P5 is swapped back in.
At time 48: An interrupt occurs from disk unit 3: P7’s write is complete.
For time 37, identify which state each process is in. If a process is blocked, further identify the event on which it is blocked.

The Beaufort Wind Scale is used to characterize the strength of winds. The scale uses integer values and goes from a force of 0, which is no wind, up to 12, which is a hurricane. The following script first generates a random force value. Then, it prints a message regarding what type of wind that force represents, using a switch statement. You are to rewrite this switch statement as one nested 150 CHAPTER 4: Selection Statements if-else statement that accomplishes exactly the same thing. You may use else and/or elseif clauses.

ranforce = randi([0, 12]); switch ranforce case 0 disp('There is no wind') case {1,2,3,4,5,6} disp('There is a breeze') case {7,8,9} disp('This is a gale') case {10,11} disp('It is a storm') case 12 disp('Hello, Hurricane!') end

Create a flowchart designing a solution to the following problem:

Anna has saved $50,000 for a down payment on a house. Your algorithm will ask Anna how much the house she would like to purchase costs (verify that the entered value is at least $10,000 and no more than $1,000,000.) If Anna’s savings is at least 20% of the house cost, provide a message that tells her that she will not have to pay for mortgage insurance. If, however her savings is less than 20%, but more than 10% provide a message that she can still purchase the home but will have to have the insurance. If unfortunately her savings are 10% or less of the home cost provide a message that she is not eligible to purchase the home and tell her the maximum home price she can afford.

The trigonometry book says: sin^2(t) + cos^2(t) = 1 Write a Python program that verifies the formula with the help of the Python Math module. Note that the trigonometric functions in the module act on the angles in radians. Your program should perform the following steps 3 times: 1. Pick a random number between 0 and 180 degrees representing an angle in degrees, say Dangle 2. Convert the angle from degrees to radians, say Rangle 3. Use the Math module to find and print the values of sin(Rangle) and cos(Rangle), and 4. Compute and print the value of the above expression: sin^2(Rangle) + cos^2(Rangle). You can then visually verify if the result printed is 1 (or close to it).
