But did you read my reply?
I need to know your requiremts, i.e. what should your code do?

double d[150]; double c[150][3],d[150] is a minimum value of c[150][3], so i want to accumulate how many numbers in column 1,2 and 3 respectively, and sum each column value. that is all..thanks a lot.
for (int k = 0; k< 150; k++)
{
if (d[k] == c[k][0])
{
sum1 = c[k][0];
sum1 = sum1 + 1;
num1 = num1 + 1;
}
if (d[k] == c[k][1])
{
sum2 = c[k][1];
sum2 = sum2 + 1;
num2 = num2 + 1;
}
if (d[k] == c[k][2])
{
sum3 = c[k][2];
sum3 = sum3 + 1;
num3 = num3 + 1;
}

something like the following?
int n;
int sum[3];
int num[3];
for (n=0; n<3; n++)
{
sum[n]=0;
num[n]=0;
}
for (int k = 0; k< 150; k++)
{
for (n=0; n<3; n++)
{
if (d[k] == c[k][n])
{
sum[n] = sum[n] + d[k];
num[n] = num[n] + 1;
}
}
}

thanks, i tried your suggestion already, but still problem...num[n] is no problem, sum[n] still has problem, when i used sum[n] += d[k], the result is sum[0] = sum[1] = sum[2] = 0; if i used sum[n] = sum[n] + 1; the result is same with num[n], what happened? thanks

i already solved this problem, finally i found, i need to change array type from int to double, because array d is double..firstly, i misinitialed int...thanks

sum1 doesn't accumulate as you are assigning a fresh value to it:

before you accumulate

Because that's exactly what you've coded it to do. Computers do what they're told, no more, no less, which may not always be what you want.

Usually, if we want to connect two clients,we have to create a server,which
will act as a bridge between the two clients,but the server must be in a WAN. Now, I want to ask ,could we create a server in a LAN?
|

A server can be in a LAN - but then it may as well not exist, and you could just connect the two clients together and do peer to peer.
Assuming both LANs have firewalls on them, then you need some sort of 3rd party they can both connect to - which I'm guessing is why you have the server in the first place.

Thank you,Iain. You know if we want to connect to a computer B in another LAN, we have to go through the "gateway" (firewalls,you refer to)of the LAN. But if B has not heard the message that we want to connect with it, B will not do "Hole Punching" for this connection, so the connection will be failed.
A server C in a WAN is the resolution, if we want to connect A and B which are in different LANs, so first,A tells C:"I want to connect with B",At the same time B tells C:"If someone wants to talk with me,please let me know".C
tells B:"A in another LAN want to talk with you",now,B will do one thing that is called "Hole Punching",if B finishes this,the connection between A and B is success.
But C must be in a WAN,can we find a server in a LAN(A or B in this LAN is best)to replace C ?

Only if there is something on that server that one of them needs (e.g., IM server). Otherwise, they can connect directly.

Where does check_name[] come from? How is initialized?
BTW enclose code in <pre> tags, for instance
<pre>
</pre>

static char check_name[12][5] = {
"A320", "A330", "B320", "B330", "D320",
"D330", "F340", "I320", "I330", "P320", "P330" };
this is how check_name is initialized.

OK, it looks fine. Now, could you please reformat OP code using <pre> tags?

The (long) code snippet of the original post.
You may also repost it, correctly formatted, of course.

Have you used the debugger to single-step through the code to find the offending statement(s)?

Comment #1: Try to remove "magic numbers" in the code.
Comment #2: check_name is intialized with how many values?
What happens in the following code if, by some chance, check_name[n] is a character string longer than 11?
char check_name[12][5];
char pns_name[12];
sprintf(pns_name, "%s.PNS", check_name[n]);
Comment #3: Walk through code in the debugger. Use small numbers.
