Anon10320,

If you run your program from within GDB, it will tell you exactly why it was killed.

Sir,
I've used gdb ,it shows that program killed by signal SIGKILL. Sir, why SIGKILL is killing my program .I've no any idea about SIGKILL and please tell me when it kills the program .

Anon10320,

If your program consumes too many resources the VM-Monitor kills it, that is what could be happening.

Sir,
In this case,if program is killed then how one can do profiling of particular program ,I mean gmon.out is not created when I run it.
>g++ -g myapp.cpp -o myapp -pg
>./myapp
>ls
myapp.o myapp.cpp myapp

Anon10320,

I took a relook at your program, it appears that you are going out of memory as you are doing a += on one string.

Thanks,
