Exercise 6
Suppose that AYBU is a new programming language that is similar to C, except that AYBU uses dynamic scoping. Consider the program below. What is the output of the program when it is:
///////////////////////////////////////////////////////////////////
int i=25;
void A(void) {
printf("A1: %d \n",i);
i--;
printf("A2: %d \n",i);
}
void C(){
static int i = 99;
i--;
printf("C1: %d\n",i);
}
void B(int i) {
printf("B1: %d\n",i);
i-=10;
A();
printf("B2: %d\n",i);
C();
printf("B3: %d\n",i);
}
int main(int argc, char** argv) {
int i=100;
printf("M1: %d\n",i);
B(i);
printf("M2: %d\n",i);
A();
printf("M3: %d\n",i);
C();
return 0;
