Can we assign a string value to "const char *var" in C langauage?

Question

Can we assign a string value directly to const char *? why memory allocation is not required here?

For example:

const char *var = "Hello";

Answer 1

Consider what's happening when you do this. You have a string literal "hello" , that exists somewhere in memory. Depending on platform and implementation, it may be read-only.

When you use it in that context, the string literal decays to a pointer to the first character, which is assigned to the pointer var .
