Nested Selection Structure in C Programming in Hindi/Urdu | 10th Computer Chapter 3
3.2.3 Nested Selection Structures
Let's closely observe the general structure of an if-else statement given below.
if (condition)
Associated Code
Else
Associated Code
The code associated with an if statement or with an else statement can be anyvalid C language set of statements. It means that inside an //block or inside anelse block, we can have other if statements or if-else statements. It also means thatinside those inner if statements or if-else statements we can have even more ifstatements or if-else statements and so on. Conditional statements withinconditional statements are called nested selection structures.All the following structures are valid nested selection structures.
1.
if (condition l is true)
if (condition 2 is true)
Associated code
else
Associated code
2.
if (condition l is true)
if (condition 2 is true)

Important Tip
In compound statements, it is a common mistake to omit one or two braces
while typing. To avoid this error, it is better to type the opening and closing
braces first and then type the statements in the block.
Did You Know?
C programming language also provides Switch-Case structure to deal with conditions, but Switch-Case structure is applicable only in limited scenarios. The if, if else structures cover all the possible decision making scenarios.
