Awk is very popular text processing tool. Awk provides different functionalies and structures like programming languages. if – if else is very useful conditional statement used to create decision trees. if – if else used to check given situation or operations and run accordingly. For example we can check the age of the person and act accordingly if over 60 or below 60 . Example Data During learning awk if- if else...
[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.

[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.

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.

var age=19; if(age>17){ console.log("You are adult"); } |
if is the starting expression of the decision tree. (age>17) is the condition we want to check. If this condition is...
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...
