Storage of const char* in memory layout

[Vinoth Rajendran4]

int main()
{
       char * str = "Hello";
       return 0;
}

Hello All,
Can you please help me understand where content of str( i.e "Hello") is stored in memory layout in C/C++.

When program is linked, typically literal string constats like your "Hello" are placed in read-only section of binary (e.g., .rodata for ELF). When program is executed, this read-only section is mapped into memory by OS.

You can read more about ELF sections and their loading at https://wiki.osdev.org/ELF. Other binary formats used by modern OSes have their differences, but main concepts are quite similar.
