Hey Guys, help me here

For the following code,
(a) Is that legal to write the code in Line 12? If yes, what is the value of b in Line 12? 5pt
(b) Is that legal to write the code in Line 15? If yes, what is the value of c in Line 15? 5pt

1  int a = 0;
2
3  if (a <= 10) {
4      int b = 20;
5      cout << "b = 20\n";
6  }
7  else {
8       if (a == 12) {
9           int c = 30;
10         cout << "c = 30\n";
11     }
12     cout << "b = " << b << endl; // Line 12
13 }
14
15 cout << "c = " << c << endl; // Line 15

Looks like line 12 is legal if '}' after line 12 is assumed as close for main.

The value of b then depends on the value of n which is not specified in your code.

 

good luck

opps... sorry.... the value of b in line 12 will be 20.

since cout << "b = 20\n"; doesnot make any differece in the value of b.

try to understand the concept of global and local variable declaration in C++ programming.

After understanding these concepts u'll know that this program is illegal (same word that u like to use I suppose :D) .
