Question

我正在尝试打开并读取txt文件，它应该显示其中的内容，但它只显示1个字符作为输出“ÿ”。

以下是源代码：

int main(){

    FILE *p;

    p=fopen("D:\\eclipse_workspace_cpp\\PL_ODEV2\\inputbookdb.txt","r");
    char c;

    do{
        c = fgetc(p);
        printf("%c",c);
    } 
    while(c != EOF);

    fclose(p);
    return 0;
}

您可以通过char读取文件char：

int main(void) {
   FILE *p;

   // Open file
   if ((p = fopen("D:\\eclipse_workspace_cpp\\PL_ODEV2\\inputbookdb.txt","r")) == NULL) {
       // Couldn't open file
       return EXIT_FAILURE;
   }

   // Step through the file until EOF occurs
   int c;
   while ((c = fgetc(p)) != EOF) {
       printf("%c", c);
       // You might use putchar(c); instead, take a look at the comment below
   }

   // Close file
   fclose(file);

   return EXIT_SUCCESS;
}

C打开并从txt文件中读取
