Question

因此，我的fprintf和fput未能成功写入所需的文件中。这是相关的代码，谢谢。

    void print_stats(double max, double min, double avg, double sum)
    {
        FILE *paid = ("paid.txt", "w");
        //paid = ("paid.txt", "w");

        if (paid == NULL)
            printf("Failed");
        fputs("Test", paid);
        fprintf(paid, "Max: %.2f\nMin: %.2f\nAverage: %.2f\nTotal: %.2f", 
        max, min, avg, sum);
        fclose(paid);

    }

您从未真正打开过文件：

FILE *paid = ("paid.txt", "w");

这将("paid.txt", "w")作为表达式求值，逗号运算符将丢弃左操作数“ paid.txt”并求值右操作数“ w”，然后将其分配给paid。

您需要在此处致电fopen：

FILE *paid = fopen("paid.txt", "w");

C-fprintf返回访问冲突写入位置0x00246D1C
