c - 调试传递两个参数的 C 程序

Question

我已经修复了代码中的一些语法错误，现在程序可以正常编译了。但是当我执行程序时，输出文件为空。输出文件应具有输入文件的相反顺序的内容。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。我似乎在 CodeLite IDE 中找不到该选项。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);
}
