Why do books say, “the compiler allocates space for variables in memory”?

Question

Why do books say, \"the compiler allocates space for variables in memory\". Isn\'t it the executable which does that? I mean, for example, if I write the following program

Answer 1

Suggest you to read compiler construction. Focus on the storage phase, your query would be resolved.

After the program gets compiled its converted to object code, which is an assembly language code. every line of a high level language program gets translated to many assembly language steps. The translated program is put into the assembler which is executed. There is STORAGE assignment phase in comiler construction which translates to Machine Operation table(MOT instructions at assembly level). This is where space allocation for variables/registers is done. There is a register modifier keyword in C++ as well.
