Write an algorithm, in pseudocode or program code, which asks a user to enter a number between 5 and 20. If they enter a number outside this range, the program asks them repeatedly to re-enter the number until they enter a valid number. If a valid number n is entered, the program asks the user to enter n temperatures (all integer values), then calculates and outputs the average temperature.

Which of these is most responsible for differences between the twentieth century to the twenty-first century?

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
