Problem #2. C language, Stack Data Placement, Pointers Consider the following program. Assume that the register SP at the beginning points to Ox0900. Answer the following questions. Assume all variables are allocated on the stack, and in the order as they appear in the program. ASCII code for character 'O' is 48. int main( void ) { volatile unsigned long int a = 67; volatile int c = -6, d = 5; volatile char mych = { 'o', '2', '4', '8' }; volatile unsigned long int *lpa = &a; volatile int *pi = &d; lpa = lpa - 2; // *lpa = *lpa + 513;// pi++; *pi = *pi + c; // Value/Address Fill in the following table by determining the values/addresses given below. Question? The number of bytes allocated on the stack for the variable declared in line 2. The number of bytes allocated on the stack for the character array declared in line 4. 3 The number of bytes allocated on the stack for all variables declared in lines 2-6. Value of mych[O] after initialization performed in line 4. Address of variable a (&a). Value of Ipa at the moment after the statement in line 7 is executed. Value of *Ipa at the moment after the statement in line 8 is executed. 9 10 Value of mych[O) at the moment after the statement in line 8 is executed. Value of pi at the moment after the statement in line 9 is executed. Value of *pi at the moment after the statement in line 10 is executed. Ox0900 TOS Comments Problem #2.
