Difference between Compile Time Errors and Run Time Errors



Compile-time

  • During compile time the source code is converted into an executable code.
Run time 
  •  During the run time the executable code which is generated during the compile time, is started running. 
Both the compile-time and runtime refer to different types of error.


Compile-time errors

  • Occurs due to the wrong syntax or semantics of any programming language.
  • The compiler will not allow to run the program until all the errors are removed from the program. 
  • When all the errors are removed , only then the compiler will generate the executable file.
  • There are two types of compile time errors. Those are
    • Syntax errors
    • Semantic errors

1. Syntax Errors

  • When we does not follow the syntax of the used programming language, then the compiler will throw the syntax error. 


2. Semantic errors

 The semantic errors occurs when the coding statements are not meaningful to the compiler.



After correcting the semantic error,



Run time errors

  • Occur during the execution and after compilation.
  • These errors are not easy to detect and compiler does not find these errors.
Examples:
  1.     Division by zero
  2.     Determining the square root of a negative number

Angular 6 - Data Binding Part 2

Image
 Data Binding - 2 Event Binding Event binding used to build interactive angular applications with the flow of data from component to the element and from element to component . Event binding syntax will have a target event name within parentheses on the left of an equal sign, and a quoted template statement on the right. Eg 1: In this example I used a button to demonstrate the event binding. In here we are binding an onClick() event to the button element. When the user clicks on the button, event binding listens to the button's click event and calls the component's onClick() method in component.ts file. Eg:2  . In here there is  a method named "onUpdateServerName" and add an event with it.

Machine Learning  What is  Machine Learning? "Machine learning is the scientific study of algorithms and statistical models that computer systems use to effectively perform a specific task without using explicit instructions, relying on patterns and inference instead. It is seen as a subset of artificial intelligence." In traditional programming, we feed a set of instructions for a defined set of scenarios to the computer. Then the computer will utilize its computing capabilities to help human process the data efficiently. In machine learning, a large amount of data is input into the computer. Then computer processes all the data and comes up with a trained model(solution). After this model is used to solve the unseen problems of the real world. Applications of  Machine Learning Machine Learning has started growing fast because nowadays we have less expensive computational power and lots of data which we can use the train our models. Therefore Machin

Selenium - 1

Selenium   Selenium is a very popular name in the software testing field which is known as an automation testing tool.  Mainly selenium uses to automate the testing of various web browsers. It supports many browsers such as, Chrome Mozilla Firefox Safari IE Advantages of Selenium Selenium is an open-source tool. Selenium supports various programming languages to write Test scripts such as, java C# Perl Python PHP Ruby It supports various operating systems, MS Windows Linux Macintosh Selenium uses less Hardware resources. Selenium supports Parallel Test Execution. Disadvantages of Selenium 1) No reliable Technical Support from anybody. (Since It is Open Source software nobody provides reliable technical support, if it is UFT/QTP Vendor (HP) provides Technical Support) 2) It supports Web-based applications only. (Selenium automates Web browsers only, using Selenium we can automate Computer Web Applications and Mobile Web Apps, but Selenium doesn’t support Computer Desktop Applications, M
