What is C++?  \nAs an extension of the C language, C++ was developed by Bjarne Stroustrup as a general purpose cross-platform language which gives programmers a high level of  \ncontrol over system resources and memory.  \n2. What is namespace in C++?  \nIf there are two or more functions with the same name defined in different libraries  \nthen how will the compiler know which one to refer to? Thus namespace came to  \npicture. A namespace defines a scope and differentiates functions, classes,  \nvariables etc. with the same name available in different libraries. The namespace  \nstarts with the keyword “namespace”. The syntax for the same is as follows:  \nnamespace namespace_name {  \n// code declarations  \n}  \n3. How to input string in C++?  \nThere are three ways to input a string, using cin, get, and getline. All three methods  \nare mentioned in the sample program below.  \n\\#include \u003Ciostream>  \nusing namespace std;  \nint main()  \n{  \nchar s[10];  \ncout \u003C\u003C \"Enter a string: \";  \ncin >> str;  \ncout \u003C\u003C \"\\nEnter another string: \"; cin.get(s, 10);  \ngetline(cin, str);  \nreturn 0;}  \n4. What is operator overloading in C++?  \nAn overloaded declaration is a declaration in the same scope of function or operator declared with the same name more than once.  \n5. How to learn C++?  \nC++ is a programming language which is an extension ofC. Thus, one should  \nprefer to learn C first (it’s not necessary). After learning C, then understand the  \nbasic difference between C and C++ . Implement all the basic programs you learnt  \nin C in C++ also. Then dive into the OOPs concept ofC++. Do as many hands-on  \nas possible to understand basic OOPs, and then dive into advanced level OOPs.  \nWhen all the basics are clear, build a small game to understand the structure and  \nremain concepts if any. By following all these steps one can learn C++ .  \n6. What is the difference between C and C++?  \nThe difference between c and c++ is that C++ is a object oriented language, which  \nmeans that it has all the features of C as well as its own thing that is the concept of  \nOOP. C++ has many functionalities of OOP that are missing from C such as  \nencapsulation, abstraction, classes, objects, etc.  \n7. How to reverse a string in C++?  \nTo reverse a string, a sample code is mentioned below.  \n\\#include\u003Ciostream>  \n\\#include\u003Cstring.h> using namespace std; int main ()  \n{  \nchar n[50], t;  \nint i, j;  \ncout \u003C\u003C \"Enter a string : \"; gets(n);  \ni = strlen(n) - 1;  \nfor (j = 0; j \u003C i; j++,i--)  \n{  \nt = s[j];  \ns[j] = s[i];  \ns[i] = t;  \n}  \ncout \u003C\u003C \"\\nReverse string : \" \u003C\u003C s; return 0;  \n}  \n8. What is template in C++?  \nA template in C++ is used to pass data types as parameters . These make it easier  \nand more simpler to use classes and functions.  \ntemplate \u003Ctypename T>  \nint fun (T a,T b)  \n{  \nreturn (a+b);  \n}  \nint main(){  \ncout\u003C\u003Cfun\u003Cint>(11,22);  \n}  \n9. What is using namespace std in C++?  \nUsing namespace std in C++ tells the compiler that you will be making use of the  \nname space called ‘std’. The ‘std’ namespace contains all the features of the  \nstandard library. You need to put this statement at the start of all your C++ codes if  \nyou don’t want to keep on writing std:: infront of every variable/string or whatever  \nstandard library feature you are making use of, as it becomes tedious to do so.  \n10. How to download turbo C++ for windows 10?  \nTo download turbo c++ follow the steps mentioned below:  \nStep-1: Download turbo C++ from [http://www.turboc8.com/p/download.html](http://www.turboc8.com/p/download.html)  \nStep-2: [Extract Turbo.C.3.2.zip](Extract Turbo.C.3.2.zip) file.  \nStep-3: Run setup.exe file.  \nStep-4: Follow the instructions mentioned.  \n11. How to paste in turbo C++?  \nPaste in turbo C++ can be done by two techniques:  \n1. Shift+Insert  \n2. Open the file in notepad with .cpp extension. Make the changes and save it. After saving the file, you can open it from the Turbo C++ application file menu  \nfrom","cbCaik92faR0uqHy","https://ap.wps.com/l/cbCaik92faR0uqHy","pdf",723770,41,"English","# C++ Programming Interview Questions\n## Core concepts and definitions\n## Practical input/output and string operations\n## OOP-related features and comparisons\n## Learning path and basic tooling","[{\"question\":\"What is C++ and who developed it?\",\"answer\":\"C++ is a general-purpose, cross-platform language developed by Bjarne Stroustrup as an extension of C.
