3. Program Control and Control Structures An algorithm is a
procedure for solving a problem in terms of the actions to execute
and the order in which the actions execute Program control
Specifying the order in which statements (actions) execute. Control
Structures Simple control statements 3 Intro to Programming with

4. The Simple if Statement Allows statements to be
conditionally executed or skipped over Models the way we mentally
evaluate situations: "If I do not have the minimum CGPA required, I
will not graduate." "If I have codeblocks installed on my machine,
I will be able to write and debug simple c++ programs." If
condition is true, body of the if statement executes If condition
is false, body of the if statement does not execute 4 Intro to
Programming with C++ Sir Noble
