compiling error
if i compile my following code in code blocks it compiles perfectly but when i try it in eclipse it shows a lot of errors. Can someone tell me what can i do?
my code is as follows****
#include<iostream>
#include<cstdlib>
#include <algorithm>
#include<ctime>
#include<iomanip>
#include<vector>
using namespace std;

i++;
}
else{j=i;break;}
}return j;
}

When you get a bunch of error like this you should always start at the top. Often later errors will just go away when you remove an earlier error.
The first warning and the first error talks about this line.
This line of code uses two new features that was added C++ in C++11 (the 2011 version of the C++ standard).
* automatic type detection
* range-based for loops
If you want to use C++11 features you need to pass the compiler flag -std=c++11 to g++.

Also, turn on as many warnings options as possible, they are your friend:
http://www.cplusplus.com/forum/general/183731/#msg899203
So, at least:
g++ -std=c++11 -Wall -Wextra -pedantic-errors
-std=c++14 if you have it, gcc 5.0 or later.
This is probably the reason why you had different results from one IDE to another, the default warning level was different. Some IDE's have no default complier warning options at all, not even -Wall - which is crazy IMO.
Good Luck !!
Edit:
Please always use code tags:
