(1) Consider the following program in C. (1) #include (2) (3) (4) (5) (6) (7) (8) (9) (10) (11) (12) (13) (14) (15) (16) (17) (18) (19) (20) int a 3; int b = 5; int main() { (21) (22) } printf("1. b=%d ", b); int b = a; int a= 2 * b; { } printf("2. b=%d ", b); int b = 1; { } int a = b; int b = a; printf("3. a=%d ", a); printf("4. b=%d ", b); printf("5. b-%d ", b); printf("6. a=%d ", a); printf("7. b-%d ", b); return 0; (a) Define the environment at the end of each of the following lines: 7, 10, 13, 17, 18, and 22. For example, at the end of lines 3 and 7 the environment is as follows 7: bla (b) What would be the output of the program (i.e., the prints in standard output)?
