C++ nested if statements
It is always legal to nest if-else statements, which means you can use one if or else if statement inside another if or else if statement(s).
Syntax:
The syntax for a nested if statement is as follows:
if( boolean_expression 1)
{
// Executes when the boolean expression 1 is true
if(boolean_expression 2)
{
// Executes when the boolean expression 2 is true
}
}
|
You can nest else if...else in the similar way as you have nested if statement.
Example:
#include <iostream>
using namespace std;
int main ()
{
// local variable declaration:
int a = 100;
int b = 200;
// check the boolean condition
if( a == 100 )
{
// if condition is true then check the following
if( b == 200 )
{
// if condition is true then print the following
cout << "Value of a is 100 and b is 200" << endl;
}
}
cout << "Exact value of a is : " << a << endl;
cout << "Exact value of b is : " << b << endl;
return 0;
}
