Dynamic String Array Size

[moonoo]

Hi ,
I have a string array defined in the main function..
I am passing the array to a function and trying to
iterate the array . My code is something like this
inside main
string tradeId[8] = { "?" , "299339Z","299323Z","301537Z","348123Z","301545Z","301535Z","347597Z"};

and inside some function i am iterating the array as
for(int arrcnt = 0 ; glbDealid[arrcnt] !='/0' ; arrcnt++)
{
cout<<glbDealid[arrcnt];

}
But it is giving core dump error . Just wanted to check whether there is some other way of finding out the array length in C++..
Regards'
Dev

It is the same array in the other function ..
I am passing the Tradid array to that function and collecting it in glbDealid array

If you use the string &quot;0&quot; to look for the end of strings table, your sode should look a bit like this:

string tradeId[8] = { &quot;?&quot; , &quot;299339Z&quot;,&quot;299323Z&quot;,&quot;301537Z&quot;,&quot;348123Z&quot;,&quot;301545Z&quot;,&quot;301535Z&quot;,&quot;347597Z&quot;, &quot;0&quot;};
.....

for(int arrcnt = 0 ; !strcmp(glbDealid[arrcnt], &quot;0&quot ; arrcnt++)
{
cout<< glbDealid[arrcnt];

}

for(int arrcnt = 0 ; glbDealid[arrcnt] !='/0' ; arrcnt++)
{
cout<<glbDealid[arrcnt];

}


Change glbDealid[arrcnt] !='/0' To

glbDealid[arrcnt-1] != '/0'

1. great '/0' quicksaab. What do you think about '\0'?
2. '\0' is a single character, but &quot;0&quot; is a string. As far as I see above glbDealid is an array of strings, not of characters [LOL]
