Question

当我尝试打印expectedRuntime变量时，它会打印expectedRuntime的地址。但我可以正确打印timeOfSubmission变量。有人可以帮帮我吗？

struct process
{
int timeOfSubmission;
int remainingRunTime;
int expectedRunTime;
char processName[20];

};

int main()
{
FILE *myInput;
myInput = fopen("input.txt", "r+");
while ( !feof(myInput) )
{

    struct process * newProcess=(struct process *)malloc(sizeof(struct process));

    fscanf(myInput, "%s", newProcess->processName);
    fscanf(myInput, "%d", & (newProcess->expectedRunTime) );
    (newProcess->expectedRunTime)=(newProcess->remainingRunTime);
    fscanf(myInput, "%d", & (newProcess->timeOfSubmission) );
    printf("%s    ",newProcess->processName);
    fflush(stdout);
    printf("%d    ",newProcess->expectedRunTime);
    fflush(stdout);
    printf("%d  \n",newProcess->timeOfSubmission);
    fflush(stdout); 
}
return 0;
}

阅读newProcess->expectedRunTime后，你用以下方法覆盖它：

fscanf(myInput, "%d", & (newProcess->expectedRunTime) );
(newProcess->expectedRunTime)=(newProcess->remainingRunTime);

有垃圾，因为没有写入newProcess->remainingRunTime。

从文件中获取结构的输入并在C中打印
