Steve earns $15.50 per hour. Assign that value to a properly named constant. Write code that enables him to enter the hours he worked in the last two days (two separate prompts). Then calculate and print Steve's pay for those two days. Express both answers in currency format with no space between the $ sign and the first digit, a comma to indicate thousands and two decimal places.

Write the Aseba code to create a 1-minute timer. At the end of 1 minute, make the robot beep using call sound.freq(440,10). It should continue to beep once every minute. Specify the values of any constants you use.

Evaluate the following Postfix: "4 9 + 8 * 1 - 6 6 + - 13 - 2 /" (All the numbers are in single digit. Everything is separated with a space)*         50.0       49.5       39.5       39       38       76

Your program must keep on prompting the user if an incorrect time was given; see below for examples. The program then converts the time into the usual US format with hours from 1 to 12, the minutes and an AM or PM marker. This conversion works like follows: • 0 hours become 12 o’oclock AM, • 1 through 11 hours become 1 through 11 hours AM, • 12 hours become 12 o’clock PM, • 13 through 23 hours become 1 through 11 hours PM, with a subtraction of 12. The program then displays the time in the usual US format. Please use care when displaying the minutes, as an extra zero needs to be displayed for minutes 0 to 9. See the examples below for details. Examples of input and output: Please enter the hours on a 24 hour clock (0-23): 15 Please enter the minutes (0-59): 7 You entered 3:07PM Please enter the hours on a 24 hour clock (0-23): 27 Please enter the minutes (0-59): 17 Sorry, your input is incorrect. Write a program clock.c that asks the user to input a moment in time as an hour…
