C++ please - 24-hour time (also known in the U.S. as military time) is widely used around the world. Time is expressed as hours since midnight. The day starts at 0000, and ends at 2359. Write a program that converts am/pm time to 24-hour time. If the input is 2:30 pm, the output should be 1430. If the input is 12:01 am, the output should be 0001.
Hints:
Think of how each hour should be handled. 12:00 am -12:59 am becomes what? 8:00 am becomes what? 12:00 pm? 1:00 pm? Group the hours into cases that should be handled similarly (e.g., 1:00 am to 11:00 am are handled the same).
Declare variables for hoursAmPm, minAmPm, and hours24. Note that minutes for 24-hour time remain the same as for am/pm, so no extra variable is needed.
Use an if-else statement to detect each case, and set the hours24 appropriately.
When outputting hour24, check if the hour is 0-9 (just check for < 10). If so, output a "0". So 7 will be output as 07. Do the same when outputting the minutes.

(Geometry: great circle distance) The great circle distance is the distance between two points on the surface of a sphere. Let (x1, y1) and (x2, y2) be the geographi- cal latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: d = radius * arccos(sin(x1) * sin(x2) + cos(x1) * cos(x2) * cos(y1 - y2)) Write a program that prompts the user to enter the latitude and longitude of two points on the earth in degrees and displays its great circle distance. The average earth radius is 6,378.1 km. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and east degrees.
Answer true or false.
1. The if…else if statement executes two different codes depending upon whether the test expression is true or false. Sometimes, a choice has to be made from more 4 possibilities.
2.it is a good practice though to use the curly braces even we have a single statement in the body

- You must use switch statements instead of if-else statements. If-else statements will not be accepted for this problem. You want to learn to play an instrument, but you need to know how much it's going to cost to buy it. The music store has the following table on their website: Write a menu-driven program that asks the user to input an instrument category and then an instrument. The program should give the user the price. The user should input an integer in the range of the choices you give them (for example, a user cannot input 3 if you only have 2 choices) and in response should be prompted to for the next set of choices. Once they make the final selection, the total should be printed to them as an integer with proper formatting as shown in the sample run. Sample run: Select a category: (1)Brass (2)Woodwind (3)Percussion 2 Select an instrument: (1)Flute (2)Saxophone 2 Your instrument will be $425.
