It also keeps check of how much hand sanitizer solution is pumped e.g. total is 500 ml, so each pump of hand sanitizer solution is 0.5 ml which is when it checks each pump using Infrared sensor.IN COARAL On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * rn, where n is the distance (number of keys) from that key, and r is 2(1.0/12.0). Given an initial key frequency, output that frequency and the next 4 higher key frequencies. Output all frequencies with five digits after the decimal point, which can be achieved as follows:Put frequency to output with 5 decimal places Ex: If the input is: 440.0 (which is the A key near the middle of a piano keyboard), the output is: 440.00000 466.16376 493.88330 523.25113 554.36526 Note: Use one statement to compute r = 2(1.0/12.0) using the RaiseToPower() function. Then use that r in subsequent statements that use the formula fn = f0 * rn with n being 1, 2, 3, and finally 4.

These are the student marks out of 25 for class tests. Subsequently the program should ask the user for a big test mark out of 50. The final mark is calculated with 50% class tests and 50% test mark. Test all values for validity. If a value is invalid, a message should be displayed, and the user should be repeatedly given chance to correct the input.The program should display the final mark, as well as the symbol of the student (see Table 1.2).The program should repeat until the user enters “-1” for the first class test.After the user has entered “-1”, the program should display a summary of the marks, i.e. the average final mark, highest final mark, and lowest final mark. The program also displays the number of students that pass (mark>=50), pass with distinction (mark>=75), and the number of students that fail (mark<50).See Figure 1.2 for example outputWrite a C/C++ program that asks the user for three integer marks.

- IN C PROGRAMMING LANGUAGE A resistor is a circuit device designed to have a specific resistance value between its ends. Resistance values are expressed in ohms (Ω) or kilo-ohms (kΩ). Resistors are frequently marked with colored bands that encode their resistance values, as shown in the Figure. The first two bands are digits, and the third is a power-of-ten multiplier. The Table below shows the meanings of each band color. For example, if the first band is green, the second is black, and the third is orange, the resistor has a value of 50 × 103 Ω or 50 k Ω. The information in the Table can be stored in a C program as an array of strings. char COLOR_CODES[10][7] = {"black", "brown", "red", "orange", "yellow", "green", "blue", "violet", "gray", "white"}; Notice that “red” is COLOR_CODES[2] and has a digit value of 2 and a multiplier value of 102. In general, COLOR_CODES[n] has digit value n and multiplier value 10n. Write a program that prompts for the colors…Part 3: Looping while(x<y) { If(z<0){ x=x+a; } Else{ x=x+z; z= -z } x=x+1; } Instructor Example 1: user input: x=5, y=2, z=5, a=5 x y z a Instructor Example 2: user input: x=2, y=13, z= -1, a=4 x y z a Looping Test Case 1: user input: x=2, y=18, z=10, a=2 x y z a Looping Test Case 2: user input: x=1, y=6, z=0, a=10 x y z aIf a and b are variables containing booleans, the expression (a and b) or (not a and not b) calculates a boolean value.
