differences in size of two

i am having a directory which contains 4 files namely 1.c,2.c,3.c and 4.c.i am reading the file names present under this directory by using readdir system call which returns to some structure variable namely myStruct.

2)I am having another open file namely a.txt file which contains file names like 1.c,2.c,3.c,4.c etc...

My intention is to compare the files present in a.txt with the files presen in the directory(just the na开发者_如何学Gome comparison is enough..not checking its contents).

when i do the comparison,even though the names present in the directory matches with those present in the a.txt file,they dont show equal comparison and then when i printed the lenghths they are unequal.

Can anyone please let me know any solution to this problem

thanks maddy

When you read from the file, there is an extra null character at the end of the line you have read, so the comparison will show that they are unequal. So after reading the line, trim off the \n and then try.
