Nothing, but be careful with the dangling else's:
if (cond1) if (cond2) stmt1; else stmt2;
means:
if (cond1) {
if (cond2) stmt1; else stmt2;
}
not this:
if (cond1) {
if (cond2) stmt1;
} else stmt2;
Yes, include files can be nested in C and C++. In fact, most library implementations do just that.

The nested loop.
Nesting can be a very handy tool in C++, but should be avoided if possible.C++ gives us If statements, For loops and many other things. These can be nested. For example:A nested If statement://outer if statementIf( this is true ){//nested if statementif( this is also true ){//do something}else{//do something else}}
I don't really get your question, so I give you an example for nested structure:struct inner1 {int i;char c;};struct outer {int i;char c;struct inner1 n1;struct {int i;char c;} n2;};valid members for a 'struct outer' type variable are:.i, .c, .n1.i, .n1.c, .n2.i, .n2.c

In C a structure within a structure is called nested. For example, you can embed a while loop in another while loop or for loop in a for loop or an if statement in another if statement.

compound c language is complicated where we need to use many nested functions and loops
Nested functions are used in some languages to enclose multiple functions and variables into a container so that individual function and variable are not seen from outside. In,C this can be done by putting such functions in a seperate source file.

In Nested Logic a Logic is contained within a Logic. If the Outer Logic is TRUE then the internal Logic is executed. Nested IF, Nested For, Nested While, e.t.c are some examples of Nested Logic in Modern Computer Languages.
Nested was created in 1977.
