Give example to convert array to Unicode

A barcode scanner for Universal Product Codes (UPCS) verifies the 12-digit code scanned by comparing the code's largest digit (called a check digit) to its own computation of the check digit from the first 11 digits as follows: 1. Calculate the sum of the digits in the odd-numbered positions (the first, third,. eleventh digits) and multiply this sum by 3. 2. Calculate the sum of the digits in the even-numbered position (the second, fourth...tenth digits) and add this to the previous result. 3. If the last digit of the result from step 2 is 0, then 0 is the check digit. Otherwise, subtract the last digit from 10 to calculate the check digit. 4. If the check digit matches the final digit of the 12-digit UPC, the UPC is assumed correct By using C++ write a program that prompts the user to enter the 12 digits of a barcode separated by space. The program should store the digits in an integer array, calculate the check digit, and compare it to the final barcode digit. If the digits match,…

Consider the decimal number (-48.325). Write down binaryrepresentation of this number using the IEEE 745 single precision format. Clearly specify “Sign”, “Exponent” and “Mantissa” fields of the single precisionrepresentation.

Suppose that we use the floating-point format with 12 decimal digits, SEEEMMMMMMMM, to rep- resent a real number, where S is the digit to represent the sign of the mantissa (use 0 for pos- itive and 5 for negative), EEE are the 3 digits to represent the exponent in excess-500 format, MMMMMMMM are the 8 digits to represent the magnitude of the mantissa, and the decimal point of the mantissa is right to the left of MMMMMMMM (i.e., SEEEMMMMMMMM representing the real number ±0.MMMMMMMM × 10EEE-500) What is the second largest positive number that can be represented in this for- mat? How much less is this number compared to the largest number? Can you represent a number located somewhere between the largest number and the second largest number?

Suppose the characters 0,1,...,8,9, A,B,C,D,E,F are used to represent a hex adecimal (base-16) number. Here A = 10 B =11,..., F = 15 What is the largest base-10 integer that can be represented with a two-digit hexadecimal number, such as 14 or 3A? (A) 32 (B) 225 (C) 255 (D) 256 (E) 272

write a program in nim to make mutable array and add elements to this array using add key word and later on print it the array and also print the length of that array

Given two sorted arrays, write a function to merge them in sorted order into a new array. Pseudocode or C++/Java/Python implementations are okay. Please explain your logic

Use one dimensional array to write c program that read five numbers, find their sum and print numbers in reverse order.

Suppose that we use the floating-point format with 12 decimal digits, SEEEMMMMMMMM, to rep- resent a real number, where S is the digit to represent the sign of the mantissa (use 0 for pos- itive and 5 for negative), EEE are the 3 digits to represent the exponent in excess-500 format, MMMMMMMM are the 8 digits to represent the magnitude of the mantissa, and the decimal point of the mantissa is right to the left of MMMMMMMM (i.e., SEEEMMMMMMMM representing the real number +0.MMMMMMMM × 10EEE-500) What are the smallest positive number and the largest positive number that can be represented in this format? Write them in exponential notation.

What are the space requirements of an array of n integers assuming each requires c bytes?
