Which of the following matches regexp /[a-z][\.\?!]\s+[A-Z]/

Please fix this code, so the answer is proper, not only 0's:  .datax: .double 0:16      # initialize x to all zerosy: .double 0:16      # initialize y to all zerosz: .double 0:16      # initialize z to all zerosmsg1: .asciiz "Enter 16 values for y and z matrices: \n"msg2: .asciiz "Resulting x matrix: \n".text.globl mainmain:    # Prompt user to enter values for y and z matrices    la $a0, msg1    li $v0, 4    syscall        # Input values for y    la $t0, y    li $t1, 16    li $v0, 7    yloop:    beq $t1, $zero, zloop        syscall    sdc1 $f0, ($t0)    addi $t0, $t0, 8    addi $t1, $t1, -1    j yloop    # Input values for zzloop:    la $t0, z    li $t1, 16    li $v0, 7    zinner:    beq $t1, $zero, multiply        syscall    sdc1 $f0, ($t0)    addi $t0, $t0, 8    addi $t1, $t1, -1    j zinner        # Multiply y and z matrices and store the result in xmultiply:    la $t0, y    la $t1, z    la $t2, x        # Loop over rows of x    li $t3, 0rows:    beq $t3, 4, print        # Loop…

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;
