使用 fscanf() 读取文本文件时出错

Question

我正在尝试使用 fscanf() 从文本文件中读取，我得到的输出是：

Process finished with exit code -1073741819 (0xC0000005)

第一次调用 fscanf() 时发生崩溃。这是我的代码：

int i=0;

FILE * trafficFile;
trafficFile = fopen("../trafficCount.txt","r");
if (trafficFile == NULL){
    printf("Could not open traffic file\n");
}

int n = 30;
fscanf(trafficFile,"%d",n);
printf("%d",n);

for (i = 0; i < n; i++){
    int temp = 0;
    int temp2 = 0;
    fscanf(trafficFile, "%d %d", temp, temp2);
    printf("%d %d\n", temp, temp2);
}
fclose(trafficFile);

感谢任何帮助。

需要将整型变量的地址传入fscanf()

fscanf(trafficFile, "%d", &n);

fscanf(trafficFile, "%d %d", &temp, &temp2);
