Doubts about using strucutre #957

Hi, Sorry i'm a newbee to c, in clox, Value is constructor like this NUMBER_VAL(value), run clox on ubuntu 20.02 desktop, i found Value structure is allocated on stack, will this cause strucutre in memory bits disturb by another method call?

No, it won't cause any problems. When you a return a value on the stack in C, it copies all of the bits.
