Explain What Is Nested If Else Statement With Example In C Programming
\\ If you have any query or questions on my post, then please comment below // What Is Nested If Else Statement:
In our previous page you learn if statement with an example and else statement with an example. In else statement you know, We are writing our program in 2 statements. But if we are having more than 2 statements, Then we can't write programs in else statement. So for writing more than one statement in c program or use if and else statement inside the if statement, c evaluated Nested If Else Statement.
Nested if else statement provides us the facility to write more than one statement in a single program.
Syntax Of Nested If Else Statement:
----------------------------------------------------------------------------------------------
if(test_condition1)
{
if(test_condition2)
{
----------------------
---------------------- // Statements1 Or True Block;
}
else
{
----------------------
---------------------- // Statements2 Or False Block;
}
}
else {
-------------------------
------------------------- // Statement 3 or false block code for test_condition1.
}
---------------------------------------------------------------------------------------
The above syntax execution goes as follows: if test condition 1 is true than test condition 2 is evaluated. If it is true then the statement 1 is executed. If the test condition 2 is false, statement 2 is executed. And if test condition 1 is false then statement 3 is executed.
Another way of writing Nested If Else Statement:
Nested If Else Statement Syntax:
----------------------------------------------------------------------------------
if(test_condition1)
{
if(test_condition2)
{
------------------ // Statement 1 Or True Block Code.
}
else
{
---------------- // Statement 2 Or False Block Code.
}
}
else
{
if(test_condition3)
{
------------------ // Statement 3 Or True Block Code.
}
else
{
---------------- // Statement 4 Or False Block Code.
}
}
--------------------------------------------------------------------------------------
The above syntax execution goes as follows: if test condition 1 is true than test condition 2 is checked. If it is true then the statement 1 is executed. If the test condition 2 is false, statement 2 is executed. And if test condition 1 is false then statement 3 is checked. If it is true statement 3 is executed, otherwise statement 4 is executed.
