试图让程序逐字读取文件，直到 EOF，无法获得 while（ .... ！= EOF）工作-解网

问：

这是我的代码，我的目的是使用 while 循环来运行代码，直到它读取 Cauchy.txt 文件中的所有单词。它只读取文件中的一些单词。有什么关于我做错了什么的指示吗？

数据是柯西.txt文件如下——

Baron Augustin-Louis Cauchy was a French mathematician reputed as a pioneer of analysis. He was one of the
first to state and prove theorems of calculus rigorously, rejecting the heuristic principle of the generality
of algebra of earlier authors. He almost singlehandedly founded complex analysis and the study of permutation
groups in abstract algebra. A profound mathematician, Cauchy had a great influence over his contemporaries and
successors. His writings range widely in mathematics and mathematical physics.

More concepts and theorems have been named for Cauchy than for any other mathematician (in elasticity alone
there are sixteen concepts and theorems named for Cauchy). Cauchy was a prolific writer; he wrote approximately
eight hundred research articles and five complete textbooks.

我试过了

#include<stdio.h>
#include<stdlib.h>
#include<math.h>
#include<errno.h>

int main()
{
    char MyString[30];

    char fname[] = "Cauchy.txt";   // File name for reading data

    FILE* finp;  // File pointer

    // The next line specifies the complete path
    finp = fopen("C:\\CodingC\\exercise 3\\ReadCauchy\\Cauchy.txt", "r");

    int status = fscanf(finp, "%s", &MyString[0]);
    // Read a few words from the input file
    if ((finp = fopen(fname, "r")) == NULL) {
        fprintf(stderr, "File %s not found\n", fname);
    }
    else {
        fprintf(stdout, "Reading file %s\n", fname);
        do {
            fscanf(finp, "%s", &MyString[0]);
            fprintf(stdout, "%s\n", MyString);
        }
        while (fscanf(finp, "%s", &MyString[0]) != EOF);
    }

    system("pause");
        return 0;
}

这是该程序的内容：

C 文件 if-语句 while-loop eof

你仍然跳过每一个其他单词，因为你读了两次，打印了一次。do/while 循环是此作业的错误工具，因为您只想在读取成功时打印。使用 do/while，您无法检查读取是否有效，直到您使用了不正确的数据。我建议重写它，以便您打开文件一次。如果文件指针为 NULL，则处理错误。如果没有，请使用我之前评论中的循环。它的作用是读取一次，然后打印一次，直到读取因任何原因失败。

这最终奏效了

#include<stdio.h>
#include<stdlib.h>
#include<math.h>
#include<errno.h>

int main()
{
char MyString[30] = { 0 };

char fname[] = "Cauchy.txt";   // File name for reading data

FILE* finp;  // File pointer



// The next line specifies the complete path
finp = fopen("C:\\CodingC\\exercise 3\\ReadCauchy\\Cauchy.txt", "r");


// Read a few words from the input file
if ((finp = fopen(fname, "r")) == NULL) {
    fprintf(stderr, "File %s not found\n", fname);
}
else {
    fprintf(stdout, "Reading file %s\n", fname);
    do {
        
        fprintf(stdout, "%s\  ", MyString);
    }
    while (fscanf(finp, "%s", MyString) != EOF);
}

system("pause");
    return 0;
}
