1. Here is a program that simply reads characters from the keyboard until the user hits the enter (or return) key. Add code to the program so that it allows the user to enter up to a 32-bit integer in hexadecimal and converts the number to int format.

(Numerical) Using the srand() and rand() C++ library functions, fill an array of 1000 floating-point numbers with random numbers that have been scaled to the range 1 to 100. Then determine and display the number of random numbers having values between 1 and 50 and the number having values greater than 50. What do you expect the output counts to be?
The first option of your program will prompt the user to enter a positive binary number (base 2 -- I's and O's only) of no more than 6 digits. Read this value as an int type value and your program must make sure that it is indeed a binary number (only I's and Os). If it isn't, then the user is prompted again. If it is binary, then your program is to calculate the equivalent decimal value (base 10 -- the number system). MSB Binary Digit LSB 256 128 64 32 16 4 2 1 Representation of a binary number So for example, converting a Binary to Decimal number would be: Decimal Digit Value 256 128 64 32 16 8 4 2 Binary Digit Value O I1 o 0 1 0 By adding together ALL the decimal number values from right to left at the positions that are represented by a "1" gives us:(256) + (64) + (32) + (4) + (1) = 35710 or three hundred and fifty-seven as a decimal number. The second option of your program will prompt the user to enter 3 positive numbers in the rangel to 10, and will tell the user whether the…
3. Write a program that input a character from user is in lowercase, the program willconvert it to uppercase and will display it on console after conversion. Hint: - The ASCII codes for lowercase letters (a-z) are 97-122. In order to convert alowercase letter to uppercase letter, just subtract 32 from its ASCII code
3. Write a program that picks a random number between 1 and 100 inclusive. It then prompts the user to guess the number. If the user guesses the number, print out a congratulatory message and exit. Otherwise, indicate whether the guess was low or high and ask the user to try again. Hint: Use the rand() function.
:Binary-Decimal / Decimal Binary . Between 0 and 255 a number will be decided randomly by computer. Then asks to user 3 times a random digit of binary value of the that number. If user enters wrong number for a digit program will select another random number and ask random times random digit. For example: Computer selected number as 163 ( Which is 10100011) What is the digit 2 (question 1/3) :User enter 1 CorrectWhat is the digit 4 (question 2/3) : User enter 0 CorrectWhat is the digit 7 (question 3/3) : User enter 0 CorrectUser finished the quest with 3 input .
Write a program that asks the user to enter 2 integers of 4 digits and displays thedifferent digits as X and * if they are the same. If the user enters a number which is notof four digits, then a convenient message is displayed.

6. A palindrome is a number or text phrase that reads the same backwards or forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a program that reads a 5 digit integer and determines whether it is a palindrome. Hint: One way to do this is to use division (/) and modulus (%) operators to separate the number into individual digits.
In this task you are required to find the common characters between strings according to certain rules and print out the result on the screen. In this task you are required to: Write a program which takes two string inputs Str1 and Str2 in addition to the mode integer value. If the value of the mode operation is not 0 or 1 then you have to print "Invalid" According to mode value you have to do the following mode=0: you have to print out the alphapatical characters that appears in Str1 but not in Str2. This operation is case sensitive which means that the lowercase and the uppercase of the same character are not the same. If the number of characters that meet this condition is 0 then you have to print None. mode=1: you have to print out the alphapatical characters that appear in Str1 and Str2. This operation is case insensitive which means that you treat the uppercase and the lowercase letters the same. If the number of characters that meet this condition is 0 then you have to print…
5. You are given a string that contains alphanumeric characters only. Your task is to sort the string in the following manner: a. All sorted lowercase letters are ahead of uppercase letters. b. All sorted uppercase letters are ahead of digits. c. All sorted odd digits are ahead of sorted even digits. Sample Input Sample Output Bracu1234 acruB1324
Write a program that reads input until encountering either the # character or the % character and then reports the number of spaces read, the number of newline characters read, and the number of all other characters read.
Using function strtod(), Create a character string that contains the following string: “78.3% is the average success rate” Divide this string into double and display the rest of the string The output will be: The original string is: 78.3% is the average success rate The extracted double value is: 78.3 The remainder of the string is: % is the average success rate
