Question

所以基本上这个Java程序打印

#!/bin/bash

echo "build script executing"

pwd
echo "ls /"
ls /

echo "***assembling the LyteByte asm files"

# move to the LyteByteAssember directory
cd ./LyteByteAssembler/

ASSEMBLY_FILE="LyteByteAssembly.lbasm"
MERGE_FILE="merge.lbasm"
OUTPUT_FILE="../BootloaderProj.cydsn/lytebyte_prog_mem_init.c"
TEMP_DIR="./"
PREPROCESSOR_DIRECTORY="c:/gitrepos/ArcherTools/LyteByteAsembler/LyteBytePreProcessor.py"

echo $PREPROCESSOR_DIRECTORY $ASSEMBLY_FILE $MERGE_FILE $TEMP_DIR
python "$PREPROCESSOR_DIRECTORY" "$ASSEMBLY_FILE" "$MERGE_FILE" "$TEMP_DIR"

if [ $? -eq 0 ]
then
     echo "Preprocessing succeeded!"
else
     echo "Preprocessing failed, process cancelled"
     exit 1
fi

但我必须让它打印

目前我在理解它时遇到了一些麻烦，如果有人能够逐步告诉我如何做到这一点会有所帮助。

Answer 1

只需颠倒循环的顺序。

int a[][] = {{4,2,7},
            {3,9,1}};
int j,i;
for(i = a[0].length - 1; i >= 0; i--)
{
    for(j = a.length - 1; j >= 0; j--)
        System.out.print(a[j][i]);
    System.out.println();
}

Answer 2

您可以简单地反转循环。
