Nesting in selection constructs, such as “if-then-else” statements, involves placing one conditional block within another. This technique allows for more intricate decision-making logic, enabling programs to handle complex scenarios. Here’s an example in Python:

x = 10
if x > 5:
print(“x is greater than 5”)
if x == 10:
print(“x is equal to 10”)
else:
print(“x is not equal to 10”)
else:
print(“x is less than or equal to 5”)

In this nested “if-then-else” construct, the outer condition checks if “x” is greater than 5. If true, it further evaluates whether “x” is equal to 10. Nested constructs allow for fine-grained control over program flow, facilitating the implementation of sophisticated decision-making processes.
