3. (Program) Write a C++ program that accepts a string from the user and then replaces all occurrences of the letter e with the letter x. 4. (Useful utility) Modify the program written for Exercise 3 to search for the first occurrence of a user-entered sequence of characters, and then replace this sequence, when it's found in the string, with a second user-entered sequence. For example, if the entered string is Figure 4-4 illustrates the output of Program 4-2 and the user enters that 4- is to be replaced by 3-, the resulting string is Figure 3-4 illustrates the output of Program 4-2. (Only the first occurrence of the searched-for sequence has been changed.) 5. (Useful utility) Modify the program written for Exercise 4 to replace all occurrences of the designated sequence of characters with the new sequence of characters. For example, if the entered string is Figure 4-4 illustrates the output of Program 4-2 and the user enters that 4- is to be replaced by 3-, the resulting string is Figure 3-4 illustrates the output of Program 3-2.

(General math) The volume of oil stored in an underground 200-foot deep cylindrical tank is determined by measuring the distance from the top of the tank to the surface of the oil. Knowing this distance and the radius of the tank, the volume of oil in the tank can be determined by using this formula: volume=radius2(200distance) Using this information, write, compile, and run a C++ program that accepts the radius and distance measurements, calculates the volume of oil in the tank, and displays the two input values and the calculated volume. Verify the results of your program by doing a hand calculation using the following test data: radius=10feetanddistance=12feet.
(Practice) Run Program 7.10 to determine the average and standard deviation of the following list of 15 grades: 68, 72, 78, 69, 85, 98, 95, 75, 77, 82, 84, 91, 89, 65, and 74.
(General math) a. Write a C++ program to calculate and display the value of the slope of the line connecting two points with the coordinates (3,7) and (8,12). Use the fact that the slope between two points with the coordinates (x1,y1)and(x2,y2)is(y2y1)/(x2x1). b. How do you know the result your program produced is correct? c. After verifying the output your program produces, modify it to determine the slope of the line connecting the points (2,10) and (12,6). d. What do you think will happen if you use the points (2,3) and (2,4), which results in a division by zero? How do you think this situation can be handled? e. If your program doesn’t already do so, change its output to this: The value of the slope is xxx.xx The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.
State whether each of the following is true or false. If false, explain why h) All arguments following the format control string in a printf function must be preceded by an ampersand (&).
-Convert SES variable to a factor and assign the value labels “low”, ”middle” and “high” to the 3 levels of thevariable. Then -Define the variables complic, comorb, depressi, diabetes as factors. For all these factors, a zero means “no” and a 1 means “yes”. Assign these value labels through the function factor() and check the change using str()
(Physics) a. Design, write, compile, and run a C++ program to calculate the elapsed time it takes to make a 183.67-mile trip. This is the formula for computing elapsed time: elapsedtime=totaldistance/averagespeed The average speed during the trip is 58 mph. b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the elapsed time it takes to make a 372-mile trip at an average speed of 67 mph.

(Electrical eng.) The amplification of electronic circuits is measured in units of decibels, which is calculated as the following: 10LOG(Po/Pi) Po is the power of the output signal, and Pi is the power of the input signal. Using this formula, write, compile, and run a C++ program to calculate and display the decibel amplification, in which the output power is 50 times the input power. Verify your program’s result by doing a hand calculation. After verifying that your program is working correctly, use it to determine the amplification of a circuit, where output power is 4.639 watts and input power is 1 watt.

(General math) a. Design, write, compile, and run a C++ program to calculate the volume of a sphere with a radius, r, of 2 in. The volume is given by this formula: Volume=4r33 b. Manually check the values computed by your program. After verifying that your program is working correctly, modify it to determine the volume of a cube with a radius of 1.67 in.

General math) a. Write a C++ program to calculate and display the midpoint coordinates of the line segment connecting the two endpoints given in Exercise 1a. Use the fact that the coordinates of the midpoint between two points with the coordinates x1,y1)and(x2,y2)are((x1+x2)/2,(y1+y2)/2). Your program should produce the following display (replacing the underscores with values your program calculates): ThexmidpointcoordinateisTheymidpointcoordinateis b. How do you know the midpoint values your program calculates are correct? c. After verifying the output your program produces, modify it to determine the midpoint coordinates of the line connecting the points (2,10) and (12,6). d. If your program doesn’t already do so, change its output to this: The x coordinate of the midpoint is xxx.xx The y coordinate of the midpoint is xxx.xx The xxx.xx denotes placing the calculated value in a field wide enough for three places to the left of the decimal point and two places to the right of it.
