C 中的 EOF、getc() 和 feof() EOF, getc() and feof() in C 在C/C++ 中,getc()在到达文件末尾时返回 EOF . getc() 失败时也会返回 EOF。因此,仅将 getc() 返回的值与 EOF 进行比较不足以检查文件的实际结尾。为了解决这个问题,C 提供了feof()仅在到达文件末尾时返回非零值,否则它返回 0。例如...
EOF, feof() in C programming By: Rajesh P.S.In C programming, checking for the end of a file is essential when reading data from a file to avoid attempting to read beyond the file's end. The most common method for checking the end of a file is using the feof function or checking...
Here is an example of EOF in C language, Let’s say we have "new.txt" file with the following content. This is demo! This is demo! Now, let us see the example. Example #include <stdio.h> int main() { FILE *f = fopen("new.txt", "r"); int c = getc(f); while (c !=...
C语言 feof()用法及代码示例C 中的 feof() 函数 原型: int feof(FILE* filename); 参数: FILE *filename 返回类型:整数(0 或 1) 函数的使用: 在C 语言中,当我们使用与文件链接的流时,我们如何确定我们到达了文件的末尾。为了解决这个问题,我们必须将一个整数值与 EOF 值进行比较。通过 feof() 函数...

feof 是C语言标准库函数，用于检测流上的文件结束符，其原型位于中。当检测到文件结束符时，feof返回非零值，反之返回0。值得注意的是，文件结束符仅能通过调用clearerr()函数清除。下面的代码示例展示了如何利用while循环结合feof函数来处理文件内容：while (!feof(in)) { ch = fgetc(in);fputc(ch, ...
feof( stream ) ){/* Attempt to read in 10 bytes: */count = fread( buffer, sizeof( char ), 100, stream );if( ferror( stream ) ) {perror( "Read error" );break;}/* Total up actual bytes read */total += count;}printf( "Number of bytes read = %d\n", total...
