Why is a constant string in a static storage zone? Char * c = "zhaobei ";The book says: "zhaobei" is treated as a constant and placed in the static memory zone of the program.The general int I = 1;1 is also a constant. Why is 1 not placed in the

First, the Java Memory Layout shallowly discusses1. General statementWe know that threads are the basic unit of operating system scheduling. All threads share the heap space of the parent process, and each thread has its own stack space and program
