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;

The following binary sequences are stored in two distinct 16-bit memory locations: Q1 A = 10010001 11000111 B = 01111010 11101000 Hint: You can use calculators/tools, but you should show the calculation procedure for each case Find both binary and decimal values of Z=A+B if A, B, and Z are all signed a integers. Find both binary and decimal values of Z=A+B if A, B, and Z are two's complement numbers. If A and B are two Boolean vectors (vectors in which every element is TRUE or C FALSE), find the outcome of the following bit-wise logical operation: (A&&B)||(!A&&!B). What would be the data type and the corresponding value of Z=A+B (written d in Python) if A and B represent two ASCII Strings (Find ASCII table in appendix). If A represent the first two bytes (network prefix) and B represents the last e two bytes (host suffix) of a class B IPV4 address, find the corresponding IP address.
