3. a. Write a for loop that prints the ASCII code of each character in a string named S. Usethe built-in function ord(character) to convert each character to an ASCII integer. b. Next, change your loop to compute the sum of the ASCII codes of all characters in a string

Write a for loop that will print the lower case letters of the alphabet backwards. Do not use ASCII codes.

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. Your algorithm should make use of the masking operation described above. The program should display the int in both hexadecimal and decimal format for the user. Assume that the user will not make mistakes. /* readHex.c * Asks user to enter a number in hexadecimal. * INCOMPLETE PROGRAM FOR EXERCISE. * 2017-09-29: Bob Plantz $/ #include #include int main(void) { int x; unsigned char aChar; printf("Enter an integer in hexadecimal: "); fflush(stdout); x = 0; read (STDIN_FILENO, &aChar, 1); while (aChar != '\n') { read (STDIN_FILENO, &aChar, 1); } // initialize result // get first character. // look for return key printf("You entered %#010x = %d (decimal)\n\n", x, x); return 0;

use C++ In this program you will be outputting the characters that map to the ASCII codes 32 through 126. You will need a loop to iterate through the input values and output the corresponding character. This mapping is shown in appendix A in your Gaddis text book. Your program will be reading in two unsigned integer values. The prompt for read will be: Enter lower and upper values You need to check that both values are in the range of 32 to 126. If the values are less than 32 or greater than 126 you need to display the message: Values must be in range 32 to 126 inclusive You will also display the above message if the first value read in is larger than the second value. If the values are invalid you need to reread the values with the prompt. Enter lower and upper values You need to keep reading in values, checking if they are valid and displaying an error message until the values read in are valid. You can use a while or do while loop to do this. Once you have valid input values you…

Using for loop, write a program that accepts an integer from the user between 100 and 1000 andchecks if it is divisible by 2, 3, 4, 5, 6, 7, 8, 9 and accordingly displays a message to the user

12. Write a loop of the specified type that sums up the even integers between 1 and 21. a. a while loop b. a for loop
