Consider the following skeletal C program- 3 pts void fun1(void); /* prototype */ void fun2(void); /* prototype */ void fun3(void); /* prototype */ void main() { int a, b, c; ... } void fun1 (void) { int b, c, d; ... } void fun2 (void) { int c, d, e; ... } void fun3 (void) { int d, e, f; ... } Given the following calling sequences and assuming that dynamic scoping is used, what variables are visible during execution of the last function called? Include with each visible variable the name of the function in which it was defined. a. Main calls fun1; fun1 calls fun2; fun2 calls funs3 b. Main calls fun1; fun1 calls fun3; c. Main calls fun2; fun2 calls fun3; fun3 calls funs1 d. Main calls fun3; fun3 calls fun1; e. Main calls fun1; fun1 calls fun3; fun3 calls funs2 f. Main calls fun3; fun3 calls fun2; fun2 calls funs1

Write a program in plp assembly that counts up by one starting from zero (or one) inside a loop and writes this value to the leds every time the value is increased. the memory address of the leds is 0xf0200000. the table below shows the meaning and an example usage of the instructions covered in the video, plp instructions for project 1. instruction example usage meaning load immediate li $t0, 8 register $t0 is set to the value, 8. store word sw $t2, 0($t1) the value in register $t1 is used as the memory address. the value in register $t2 is copied into this memory address. add addiu $t4, $t3, 29 register $t4 is assigned the sum of 29 and the value in register $t3. jump j your_label_name the program jumps to the line following the label, "your_label_name: ". label your label name: defines a label called "your_label_name: " that can be jumped to
