6 SMBE 2033 Q3. A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Given the C code and memory content mapping shown in Figure 4, complete the Table 2 after the program execution. #include Ox11223344 a int main() int a = 2018, b = 2020; Ox12345678 b int *ptr_a=&a, *ptr_b=&b; Ox8899AABB ptr_a *ptra = a + 50; *ptr_b = *ptr_b - *ptr_a; 0x89ABCDEF ptr_b ptr_b = ptr_a; return 0; Figure 4.
