我在代码中修复了一些语法错误，现在程序编译得很好。但是当我执行程序时，outputFile为空。 outputFile应该以相反的顺序包含inputFile的内容。我正在尝试在CodeLite IDE中调试代码。
我需要使用传递的两个参数（inputFile和outputFile）来调试代码。我似乎没有在CodeLite IDE中找到该选项。我该怎么做？
#include <fcntl.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#define BUFFER_SIZE 256
int main (int argc, char *argv[]){
FILE *inputFile, *outputFile;
int fileSize;
int pointer;
char buffer[BUFFER_SIZE];
/* Check for correct user's inputs. */
if( argc !=3 ) {
fprintf(stderr, "USAGE: %s inputFile outputFile.\n", argv[0]);
exit(-1);
}
/* Make sure input file exists. */
if( (inputFile = fopen(argv[1], O_RDONLY))) {
fprintf(stderr, "Input file doesn't exist.\n");
exit(-1);
}
/* Create output file, if it doesn't exist. Empty the file, if it exists. */
if((outputFile = fopen(argv[2], "a+"))) {
fclose(inputFile);
exit(-1);
}
/* Find the size of the input file. */
fileSize = fseek(inputFile, 0, SEEK_END);
/* Read input file and write to output file in reversed order.*/
for(pointer=fileSize-1; pointer>=0; pointer--) {
/*Write content in the buffer to the output file */
while(!feof(inputFile))
{
fgets(buffer, BUFFER_SIZE, inputFile); //reads 256 bytes at a time
fputs (buffer , outputFile );
}
}
fclose(inputFile);
fclose(outputFile);
return(0);
}
