9. ‘if’ is called single selection structure because it select or ignore a single action. Syntax(general form):- if(condition) { c++ expression or statement ; } http://indiannova.in

11. A nested if is an if that has another if in its if’s body or in its else’s body. Syntax :- If(condition ) { c++ expression ; } if(condition ) { c++ expression ; } else { C++ expression ; } else { C++ expression ; } If(condition ) { c++ expression ; } if(condition ) { c++ expression ; } else { C++ expression ; } else { C++ expression ; } http://indiannova.in
