Question

我正在编写一个程序来执行此操作但有错误消息。我已将fopen-s行更改为现在的行，但输入两个文件名后会出现此消息？ error message

这里没有Visual Studio中出现的错误消息，但不确定这不是问题。

#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>

int main()
{
//setting names of ints and chars.
FILE *file_in;
int wordcount, linecount, charcount;
char letter;
char filename1[50];
char filename2[50];

//setting all counts to 0.
wordcount = 0;
linecount = 0;
charcount = 0;

//Gets the user to enter name of file, then puts it in string.
printf("\n Enter first text document\n");
gets_s(filename1);
printf("\n Enter second text document\n");
gets_s(filename2);

//opens then reads the first file.
fopen_s(&file_in, filename1, "r");

    // counts the number of words, then lines, then letters in doc 1. 
    while ((letter = getc(file_in)) != EOF);
    {
        if (isspace(letter) && !isspace(getchar()))
        {
            wordcount++;
        }
        if (letter == '\n');
        {
            linecount++;
        }
        if (letter == '-')
        {
            charcount++;
        }
    }

    //opens then reads the second file.
    fopen_s(&file_in, filename2, "r");

    // counts the number of words, then lines, then letters in doc 2.
    while ((letter = getc(file_in)) != EOF);
    {
        if (isspace(letter) && !isspace(getchar()))
        {
            wordcount++;
        }
        if (letter == '\n');
        {
            linecount++;
        }
        if (letter == '-')
        {
            charcount++;
        }
    }

    //displays the total on screen.
    printf_s("Words:", wordcount, "\n");
    printf_s("Letters", charcount, "\n");
    printf_s("Lines", linecount, "\n")

}

Answer 1

fopen_s需要3个参数。首先是指针，你要为其分配文件，第二个是文件名，第三个是你想要如何访问文件（＆＃34; r＆＃34;，＆＃34; w＆＃34;等）

Answer 2

我发现这里有一些变化......这段代码对我有用：

#include "stdio.h"
#include "stdlib.h"
#include "ctype.h"

int main(int argc, char *argv[])
{
    //setting names of ints and chars.
    FILE *file_in;
    int wordcount, linecount, charcount;
    int letter;
    char filename1[50];
    char filename2[50];

    //setting all counts to 0.
    wordcount = 0;
    linecount = 0;
    charcount = 0;

    printf("Enter first text document: ");
    fgets(filename1, 50, stdin);
    ch = filename1;
    while(*ch != '\n')
        ch++; 
    *ch = '\0';
    printf("Enter second text document: ");
    fgets(filename2, 50, stdin);
    ch = filename2;
    while(*ch != '\n')
        ch++; 
    *ch = '\0';

    //opens then reads the first file.
    file_in = fopen(filename1, "r");

    // counts the number of words, then lines, then letters in doc 1. 
    while((letter = fgetc(file_in)) != EOF)
    {
        if (letter == ' ')
        {
            wordcount++;
        }
        else if (letter == '\n')
        {
            linecount++;
        }
        else
        {
            charcount++;
        }
    }

    //displays the total on screen.
    printf("File 1...\n");
    printf("Words: %d\n", wordcount);
    printf("Letters: %d\n", charcount);
    printf("Lines: %d\n", linecount);

    //opens then reads the second file.
    file_in = fopen(filename2, "r");

    //reset counts
    wordcount = 0;
    linecount = 0;
    charcount = 0;

    // counts the number of words, then lines, then letters in doc 2.
    while((letter = fgetc(file_in)) != EOF)
    {
        if (letter == ' ')
        {
            wordcount++;
        }
        else if (letter == '\n')
        {
            linecount++;
        }
        else
        {
            charcount++;
        }
    }

    //displays the total on screen.
    printf("File 2...\n");
    printf("Words: %d\n", wordcount);
    printf("Letters: %d\n", charcount);
    printf("Lines: %d\n", linecount);
}

C程序要求两个单独的文件，然后显示字符数，行数和单词数
