4. Sequential control structure
programs
The program flow in high-level
languages is sequential, i.e., it
executes line-by-line from top to
bottom.
Each statement is executed only
once.
Such programs where statements
are executed in a linear fashion are
known as sequential control
structure programs.
5. CONTROL STRUCTURES
statements can be used within a
program to execute decisions or to
repeat actions.
These actions may require the
linear sequence of instructions in a
program to be changed.
Special constructs/statements are
used to achieve these.
These constructs/statements are
conditional statements and iterative
statements.
6. Sequence
Sequence refers to a group of
instructions executed one after
another, without any condition
checking or repetition.
The programs discussed in the
previous chapter are based on
sequence control structure.

8. Selection
The selection statement selects
from two alternative routes
depending upon whether the
condition is true or false.
Any non-zero and non-null values
are treated as true and zero or null
values are treated as false.
