Most compilers have specific storage class qualifiers for variables mapped to flash, and also require a respective pointer definition. Usually the keyword const or rom qualifies programm memory variables. Technically this required by the processor architecture with separate busses and instructions for data and programm memory.

According to GCC manual, this should work

Code:

const __flash char str[] ={"arun sharma"};
const __flash char *p;
p=&str[0];
// or 
p=str;
