C编程需要LValue

问题描述：

，我是C的初学者。

我有以下代码，我在第29,30和31行遇到错误。

错误是 - LValue必需。

,I am beginner to C.
I have the following code where i am getting error in Lines 29,30 and 31.
the error is - "LValue required".

#include<stdio.h>
#include<conio.h>
struct employee
{
	char empname[30];
	int leave;
};
void main()
{
	struct employee a[1000];
	int bp=5000, salary,x,i,j,k;
	x=(bp*120)/100;
	salary=bp+x;
	printf("Enter the number of employees:");
	scanf("%d",&j);
	for(i=0;i<j;i++)>
	{
		printf("Enter employee name and number of days he/she took leave:");
		scanf("%s%d",&a[i].empname, &a[i].leave);
	}
	for(i=0;i<j;i++)>
	{
		for(k=i+1;k<j;k++)>
		{
			if(a[i].empname[0]>a[k].empname[0])
			{
				char w[30];
				int t;
				w=a[i].empname;
				a[i].empname=a[k].empname;
				a[k].empname=w;
				t[i]=a[i].leave;
				a[i].leave=a[k].leave;
				a[k].leave=t[i];
			}
		}
	}
	for(i=0;i<j;j++)>
	{
		if(a[i].leave>10)
		salary=salary-((a[i].leave-10)*366);
	}
	for(i=0;i<j;i++)>
	{
		printf("Employee name = %s\nNumber of days leave = %d\nSalary = %d\n",a[i].empname,a[i].leave,salary);
	}
	getch();
}

你能帮我解决原因和正确的解决方案吗？

你有更大的问题就是这 - 看起来它是从一个组装而成套件......

正如理查德所说：你不能将变量声明为一个数组，然后期望复制数据并指定一个新指针。

但是......你也不能把>在for循环结束时，你不能使用整数作为数组，大多数年份没有366天...

我建议你尝试模块化这个程序：将其分为三个函数：一个用于获取输入，一个用于对数据进行排序，另一个用于输出。

然后获取每个函数在你继续写下一个之前工作 - 并且请让你的生活更轻松：停止使用一个角色名称。例如，要弄清楚j对employeeCount的作用要困难得多。请记住，您将在几周内回到此状态，现在让它可读，这意味着您可以节省下次工作时间。

You have bigger problems that just that - this looks like it was assembled from a kit...
As Richard says: you can't declare a variable as an array and then expect to copy the data bu assigning a new pointer.

But...You also can't put a ">" on the end of for loops, you can't use an integer as an array, and most years do not have 366 days...

I would suggest that you try to modularise this program: break it into three functions: One to get the inputs, one to sort the data, and one to output it.

Then get each one to work before you move on to writing the next - and please, to make your life easier: stop using one character names. It is a lot harder to work out what "j" does that it is for "employeeCount", for example. Remember, you will come back to this in a few weeks, and making it readable now means you save time working it all out next time.
