12. The table below lists approximations in meters of the longest wavelengths in each region of the electromagnetic spectrum. The final column gives these m lengths as they would be represented in C scientific notation. You can see that the "E" would be read as "times 10 to the power." Numbers in this format can be used as constants. They can be scanned in using the %lf placeholder. However, to output a number in scientific notation, use the %e placeholder. Note that visible light makes up a tiny fraction of the full spectrum. Write a program that repeatedly prompts the user to enter a wavelength in scientific notation (or zero to quit) and displays for each entry the wavelength and the region of the spectrum into which it falls. Note that zero is used as a sentinel, so no region should be displayed when the user enters zero.

1.Write a program that will read in the names (multiple-word string, ie with blanks) and sales amounts (float) for 2 staff members. It will then print the values in the following format. Use gets() functions to read the string values. Use field modifiers to format the output, so that the field width for staff name is 20 and it is left-justified. The field width for sales amount is 12 with 2 decimal places. (Use C code (stdio.h, scanf, get, printf...) to create the program.)

In each question below, provide a brief explanation, a formula and the numerical value for your answer (exact if the answer is an integer, approximate otherwise). There are 94 printable characters on a standard North American keyboard, comprised of the 26 upper case letters A-Z, the 26 lower case letters a-z, the 10 numerical digits 0-9 and the 32 special characters. For our purposes, passwords are strings consisting of printable characters. The length of a password is the number of characters in the password. Suppose we want a password space with entropy 128 bits, assuming that each pass- words is equally likely, i.e. a total of 2^128 passwords (this number is typical for key space sizes of modern cryptosystems). Assuming no restrictions on the characters appearing in passwords ex- cept that they be printable, what is the minimum password length that guarantees a password space with entropy 128?
Write a program that calculates the Euclidean distance and the Manhattan or taxicabdistance between two two-dimensional points. Make sure you 1) use a point structureto store the points (see above), 2) use functions to calculate the two distances and3) ask the user for the point data. The Euclidean distance is calculated using thePythagorean Theorem for (points (x1,y1),and (x2, y2):euclidean = ( x1-x2)^2 + ( y1-y2)^2And the Manhattan distance is calculated as:manhattan = | x1-x2 | + | y1-y2 |
Three variables, x, y, and z, supposedly hold strings of digits, suitable for converting to integers. Write a code that converts these variables into integers and print sum of the three integers. However, if any variable has a value that cannot be converted to an integer, print out, the string "bad value(s) in:" followed by the names of the variables that have bad values (separated by spaces, in alphabetically ascending order). For example, if the values of x, y, and z were respectively "3", "9", "2" then the number 14 would be printed; but if the values were "abc", "15", "boo" then the output would be: bad value(s) in: x z

Question 3: Write a function that computes the ratio of vowels vs. consonants (????????????????��) in a given sentence. The ratio should be given as a floating-point number rounded off to two decimal places. When writing your function, be sure to appropriately cater for the following punctuation marks: apostrophes (') quotations (") full stops (.) commas (,) exclamations (!) question marks (?) colons (:) semicolons (;) Arguments: sentence (string) →→ sentence required to compute the ratio. Return: ratio (float) →→ a ratio that describes the number of vowels to consonants: vowels/consonants. ?HINT? Remember to cater for the white spaces that appear in your sentence. Expected outputs vowel_consonant_ratio("This is a random sentence!")==0.62 vowel_consonant_ratio("Thomas! Where have you been?")==0.83
Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1 below. Expression Effect strVar.at(index) Returns the element at the position specified by index strVar[index] Returns the element at the position specified by index strVar.append(n, ch) Appends n copies of ch to strVar, where ch is a char variable or a char constant strVar.append(str) Appends str to strVar strVar.clear() Deletes all the characters in strVar strVar.compare(str) Returns 1 if strVar > str returns 0 if strVar == str; returns −1 if strVar < str strVar.empty() Returns…

Do not add a linefeed. Examples: num pattern // 1 * // 2 ++ // 3 [*] // 4 {++} // 5 [[*]] // 6 {{++}} // 7 [[[*]]] void printPattern2(size_t num){}
Using, HTML,CSS , and javascript Write a program that takes as input the speed of a car e.g 80. If the speed is less than 70, it should print “Ok”. Otherwise, for every 5 km/s above the speed limit (70), it should give the driver one demerit point and print the total number of demerit points. For example, if the speed is 80, it should print: “Points: 2”. If the driver gets more than 12 points, the function should print: “License suspended”.
