C – If Else , Switch, Decision Making

[rps-include post=6557] Conditions or Decisions making is one of the most important aspect of programming languages. Actual programming logic is implemented in the decisions. According to decisions the application will be branched and expected results or operations will be accomplished. There are 3 main decision making mechanisms. We will look in details below. If The syntax of if is like below in C programming language.

with if(boolean_expression) if boolean_expression is true code...

Linux Bash If-Else Conditionals

[rps-include post=6835] If-Elif operators are used to design flow of the bash script. We can change the flow according to given conditions with If-Elif . If When writing scripts we have a lot of situation to make decision. We solve the questions marks of the scripts with conditionals. For example the simplest one is we want to run script if a directory or file exist.

If  Clean.sh exists then echo The most...

Javascript Decision Making with If-Else

Programs are mainly written on decisions. Decisions makes an application more flexible and rich. Javascript supports decisions too. A decision example might be like this: If person age above 17 set him adult. Single If We can define more complex decisions but for now we will look into simple decision.

if is the starting expression of the decision tree. (age>17) is the condition we want to check. If this condition is...

Python Pass Statement

Python provides different keywords which do not exists in other programming languages.  pass is one of the original keyword used for  nothing. pass keyword is a requirement for python block specification and syntax. Why To pass? Other languages generally uses some block specifier like {} or ;  etc. For example we can define functions but if we do not provide the body this may create some conflicts. So we need some statement...

Python If-Elif-Else Multiple Conditionals Like And , Or

We have already looked if-elif-else statements in previously. if-elif-else requires conditions in order evaluate. These conditions may simple True , False or comparisons. The other way is we can define complex conditionals in order to evaluate. Simple Conditions Simple conditions are just single statement conditions where we do not need grouping or multiple or , and . We will just check if the value is bigger than 50 in this example.

Multiple Conditions And Operator The...

Python Boolean Variable Types

Logic operations are one of the important topics in application development. Python supports logic operations and value as boolean. Boolean is data type used to represent logic values True and False. True generally used to positive or enabled situations. False is generally used negative or disabled situations. For example if we want to express existence of an item we will use boolean value. Create Boolean Variable Creating boolean value is easy as defining...

Python If .. Elif .. Else Statements and Conditionals

Decision making one of the fundamentals operations in programming languages and applications. We mostly use decisions to implements applications logic. The primary mechanism for decisions in Python is if..elif..else keywords. We can simple call them if-else . In this tutorial we will look different aspects and usage  examples of if-else. If If is used to check whether given condition is true and run some code. So we need some condition and some code...

Powershell If-Elseif-Else Conditional Statement

Powershell is a really powerful scripting language. It provides  a lot of modern useful programming language features. It also have basic features like conditional statements like If . In this tutorial we will look syntax and use cases of If . If is used to check if specified condition/s are met and if the condition is met do something if not check other conditions or exit. We will look different usage...

Powershell Comparison Operators Like Equal, Greater, Lesser, Contains, Regex

Comparison operator is used to compare given values and return an boolean value like true and false . These operators are generally used by if , while and similar decision making keywords. All comparison operators are case-insensitive by default. So the uppercase or lowercase expression do not changes the behaviour of these comparison operators. Equal One of the most used comparison operator is equal. This operator check whether given values are equal or not...
