问题描述
我正在尝试读取和打印.txt文件中的内容.
后来我也想从mips中读取转储的文件.
我看到了代码,看起来还可以,但是什么也没输出...
I'm trying to read and print the content inside a .txt file.
Later i'd like to read the dumped file from mips aswell.
I see the code and it seems ok but nothing is outputed...
.data
myFile: .asciiz "teste.txt" # filename for input
buffer: .space 1024
.text
# Open file for reading
li $v0, 13 # system call for open file
la $a0, myFile # input file name
li $a1, 0 # flag for reading
li $a2, 0 # mode is ignored
syscall # open a file
move $s0, $v0 # save the file descriptor
# reading from file just opened
li $v0, 14 # system call for reading from file
move $a0, $s0 # file descriptor
la $a1, buffer # address of buffer from which to read
li $a2, 11 # hardcoded buffer length
syscall # read from file
# Printing File Content
li $v0, 4 # system Call for PRINT STRING
la $a0, buffer # buffer contains the values
syscall # print int
li $v0, 10 # Finish the Program
syscall
推荐答案
问题出在我文件的path
上.
我以为路径将从源代码开始,但是从.jar
文件开始.
The problem was about the path
of my file.
I thought the path would start from the source code, but it starts from the .jar
file.
我要做的就是提供带有double \\
All I had to do is provide a fullPath with double\\
.data
myFile: .asciiz "c:\\Users\\johnDoe\\Documents\\Assembly\\test.txt" # filename for input
