Error in creating map iterator

amanyasin (66)
Hi

Dear all

Kindly can you help me to solve the error in creating map iterator.

.h , .cpp and error list are attached. I found there is error in creating map iterator (error C2374: 'map_Iter' : redefinition; multiple initialization ).

First of all there is no other definition of map_Iter also i tried to solve by different names and ways but nothing. So, please guide me

Thanks in advance.

I believe you want a semi-colon at the end of line 38 of your .cpp file.

std::map <string, resultBackup>::iterator map_Iter,
