Answer:

Remove the "\n" from " Pounds\n".


Read String

li      $v0,8       # code 8 == read string
la      $a0,buffer  # $a0 == address of buffer
li      $a1,16      # $a1 == buffer length
syscall             # Invoke the operating system.

 . . . .

        .data
buffer: .space 16   # reserve 16 bytes

The read string service reads a string of characters into a memory starting at the address in $a0. A block of bytes used this way is called a buffer.

Register $a1 contains the length (in bytes) of the input buffer. Up to ($a1)-1 characters are read from the keyboard and placed in buffer as a null terminated string.

The user types in characters and then ends the string by hitting "enter". The characters are copied into the input buffer.

The "enter" character appears in the buffer as the newline character '\n', 0x0a. This byte is followed by the null byte 0x00. If the user enters a string that is exactly ($a1)-1 characters long the newline character is omitted from the buffer. No matter what, there is a null at the end of data in the buffer.


QUESTION 10:

Is the string that is read in immediately suitable for output using the print string service?
