Answer 1

1.Ans. The source code for a program can include code from the C++ standard library. A source code is a code which is wrote by human easy to understand as it is written in high level languages.Now in a source code we use header files such as iostream.h(input output stream),math.h,stdlib.h etc these all are header files which are in the C++ standard library.

2.Ans. the code completion feature This feauture helps to identify and corrects errors which helps to save time.

3.Ans All the above The IDE provides the programmer to write the souce code in high level language C++ compile it into object code and also run it.

4.Ans.  a and b only A console appllication is a text based interaction which takes input from user in text form an display the result in text form. GUI is not needed for this application to use.

5.Ans.  Project An IDE Stores stores all the file of a program in project.It is a group of files that together forms a program.

6.Ans. Compiler compiles the source code HLL(High Level Language) into the object code /machine code(low Level language).

7.Ans.  Your code compiles and runs faster In typical IDE for  C++ code compilation and excution has to be perfect.Although it is great to run the program faster but it is better that code is optimised and run well.

8. Ans.  Code Editor Programmer uses Code editor that helps to write and edit source code in a IDE.It is used to create programs or software.It helps to create coding for building of a program.

9.Ans.  Its syntax is easier to learn than the syntax of other languages like C# and Java  C++ is more complicated than that of Java .Java is easy to learn It as it is a easy  high level langauage and its syntax is easier than C++.

10.Ans.  there’s a syntax error in a C++ statement If the syntax while writting the code is there is a spelling mistake or a semicolon comma missing or any operator keywords missing.
