c++ - fscanf() 输出错误值

Question

我正在尝试从文本文件中读取整数。然而这段代码不断地打印 i 的值。因此它会继续打印文件中的零而不是整数。我该如何解决？谢谢!

FILE* inFile = fopen(filename,"r");
    int i=0;
    int x;


    while(fscanf(inFile,"%d",&i)!= EOF){
            printf("%d\n", i);
            usleep(30000);
            //fscanf(inFile,"%d",&i);

    }
    fclose(inFile);

Answer 1

fscanf() 返回成功扫描的字段数。

所以而不是

while (fscanf(inFile, "%d", &i) != EOF)

尝试类似的事情

while (fscanf(inFile, "%d", &i) == 1)
