Question

Consider the following in C

int main() { float x = 3.14, *p = &x; int r, a = 2, b[] = {5, 6, 7}; <more code here> r = Foo(x, p, &a, b) <more code here> }

Answer 1

Answer #1

Statement 1: *y += 1.86

p is a variable of type float *, the value that it points to(variable x) incremented by 1.86. x in the main() function will change to 5.00.
Also, since there is no modification in local variables or parameters of foo() there is no change in its AF.
howver, the value of x changes, since this is a local variable in main() , the AF of main will change
Answer:
Result : x = 5
change in foo() AF: NO
change in main() AF: YES

statement 2: z+= 1

statement 3: w[1] += 20.

statement 4: return *z + *w

The values in *z and *w is being added and returned.
The value of r in the main() function stores this return values, so it will be altered.
The return value will be 2+5 = 7
Answer:
Result: 7
change in foo() AF: no
change in main() AF: yes
