被认为是C中的char *和C中的const char *,对于这两种语言,字符串文字存储在只读存储器中.(如果我错了,请纠正我)

#include <stdio.h>
 
    int main(void)
    {
     const char* c1;
     const char* c2;
 
     {
      const char* source1 = "Hello";
      c1 = source1;
 
      const char source2[] = "Hi"; //isn't "Hi" in the same memory region as "Hello" ?
      c2 = source2;
     }
 
     printf("c1 = %s\n",c1); // prints Hello
     printf("c2 = %s\n",c2); // prints garbage
 
    return 0;
    }

为什么source1和source2的行为不同？(使用gcc -std = c11 -W -O3编译)
