I am getting bit strange result in both this case above.
In case 1:
when I am passing f in find() function which is define in this function then in the result I am getting valid iterator and it showing the exact result.
In case 2:
when I am passing languageName(which is having "vivek" or any cstring in that map) in find() function in that case I am not able to get the valid iterator value.
After doing lot of debugging I have to know this behavior. Please let me know the exact reason.

Thanks a lot.

Replace GetName2(); with GetName2(c); in main.
