文件读取的问题----末尾多一个空格

Posted 2020-11-11 jakejian

#include "stdafx.h"
#include <stdio.h> 
#include<Windows.h>
int main() {
    char* filename=new char[1024];
    filename = "E:\\\\下载文件\\\\vs2016\\\\first\\\\first\\\\mingwen.txt";//任意一个自己有该txt文件的路径
    FILE *fp;
    if ((fp = fopen(filename, "r")) == NULL)
    {
        printf("无法打开此文件\\n");
        exit(0);
    }
    char *miwen = new char[1024];
    int i = 0;
    while (!feof(fp)) {
        miwen[i++] = fgetc(fp);
    }
    //i--；
    miwen[i] = ‘\\0‘;
    
    printf("%s",miwen);
    getchar();
    return 0;
}

在getchar();处加断点进行调试，得
