The number inside the brackets of an array definition is the _________, but the number inside an array’s brackets in an assignment statement, or any other statement that works with the contents of the array, is the _________.
Program Number 2: Password Verifier Imagine you are developing a software package that requires users to enter their own passwords. Your software requires that user’s passwords meet the following criteria:
The password should be at least six characters long.
The password should contain at least one uppercase and at least one lowercase letter.
The password should have at least one digit.
Contains at least one @ in array.
Write a program that asks for a password and then verifies that it meets the stated criteria. If it doesn’t, the program should display a message telling the user why.
FYI: Please write the code in Pseudocode (no programming language please)
1. Write pseudocode to load a single array with data. Then search that array for a match. Here are the specifics. You do NOT have to write the entire program.
Load the array with data from a file named customerNumbers
Ask the user to enter their customer number
Search the array for the customer number
If you find a match output FOUND
If there is no match output NOT FOUND

- (Electrical eng.) Write a program that declares three one-dimensional arrays named volts, current, and resistance. Each array should be declared in main() and be capable of holding 10 double-precision numbers. The numbers to store in current are 10.62, 14.89, 13.21, 16.55, 18.62, 9.47, 6.58, 18.32, 12.15, and 3.98. The numbers to store in resistance are 4, 8.5, 6, 7.35, 9, 15.3, 3, 5.4, 2.9, and 4.8. Your program should pass these three arrays to a function named calc_volts(), which should calculate elements in the volts array as the product of the corresponding elements in the current and resistance arrays (for example ,volts[1]=current[1]resistance[1]). After calc_volts() has passed values to the volts array, the values in the array should be displayed from inside main().arrow_forwardFill-in-the-Blank By using the same _________ for multiple arrays, you can build relationships between the data stored in the arrays.

You should ask the user the number of integers user would like to enter (this will allow you to set the length of the array). Allow the user to input all the numbers and then store them in the array. Search the array for the largest number, then search for the smallest, and finally compute the calculation. Display all the numbers given by the user, the max number, the min number, and the difference. (Use Loop, Array)arrow_forward
