Please read Source Code Indentation for the basic idea first.
Some programming languages support nesting of functions. Such source code would look like the following if
the indentation rules suggested here are applied:
An Example:
1: function SomeFunc(A, B, C)
2: {
3: if(A > B && B > C)
4: return -1;
5:
6:
7: function ProcessIt(X, Y)
8: {
9: if(Y < 0)
10: return -1;
11:
12: if(X * X > Y)
13: return -2;
14:
15: var A= X * X;
16: var B= Y * Y;
17:
18: var Result= A + 2;
19: if(B < 100)
20: Result+= B;
21:
22: return Result;
23: }
24:
25:
26: var ValAB= ProcessIt(A, B);
27: var ValAC= ProcessIt(A, C);
28: var ValBC= ProcessIt(B, C);
29:
30: return ValAB * ValAB + ValAC * ValAC + ValBC * ValBC;
31: }
|
Here the return statements inside the ProcessIt(.) function terminate only the ProcessIt(.)
function, but not the outer SomeFunc(.) function. Therefore they are indented the same level as the declaration
of the ProcessIt(.) function is. Conversely, the return statements which terminate the SomeFunc(.)
function are indented according to the SomeFunc(.) funciton.
