hello Aryan,
ur string c is empty .
first declare string c of size n and then perform the required operation ,it will work.

Now showing Segmentation Fault.
Sir as you told, But I had declared that string as string a,b,c and then performed the operation on that.
So, It should print the result.

Sir, I have a doubt. Please tell me that as I did a-b and stored it in the integer, Will it not be an Implicit Typecasting. Compiler will do that only.

@cbcao263
arayan,
a)No typecasting will not be implicit compiler will take xor of their ascii value .
b) u are using char array so it should end with null character i.e \0 .
so first declare ur c array of size n+1 .
then after loop c[n]=’\0’;
and then print c.

or u can use c++ string.
just u need to declare ur string c as
string c(n,’ ');
and rest everthing will remain same

Sir Is It Okay now and Please see the commented part too. Please tell mistake in that.
