The program works fine when i dont declare a string.
I am using LM3S3748. Please Help me. Thank You
do you have enough stack space?
I am sorry but how would i set the stack space and check if it is full
For one way to check, see:

The initial Stack Pointer value is set in the startup code...
you really cannot expect to be able to solve problems associated with your system if you do not know the basics. you must read the data sheet / user manual of the processor / display, and of course also to get acquainted with the Keil IDE.
Indeed!
Luminary (now TI) provide a startup_rvmdk.S in each of their sample pojects provided in the StellarisWare package. This includes all of the DevKit samples.
