Question

所以我的所有功能都正常工作，除了我的：

void printWorkers(int numOfWorkers);

函数，它没有执行，我以为我把所有变量和声明放在正确的位置，所以我不知道是什么阻止它执行。

    int age;
    char sex[2];
    int tenure;
    double salary;
    } payroll;

int readFile();
void strsub (char buf[], char sub[], int start, int end);
void printWorkers(int numOfWorkers);
payroll workers[MAX];

int main()
{
    int numOfWorkers = 0;


        if (!(fpIn = fopen("payfile.txt", "r")))
    {
        printf("payfile.txt could not be opened for input.");

        exit(1);
    }

    readFile();

    numOfWorkers = readFile();

    printWorkers(numOfWorkers);

    return 0;
}

            sscanf(buf+65, "%lf", &workers[i].salary);

            ++i;

}

Answer 1

您正在拨打readFile两次：

readFile();

numOfWorkers = readFile();

第二次绕过它会返回0，因为它已经达到了EOF。并且你printWorkers使用0来完全迭代0次，因此它看起来好像没有被调用，即使它被调用。

Answer 2

READFILE（）;
numOfWorkers = readFile（）;

在这里删除第一个。

功能未正确执行
