In this we are assessed by asking us to do mini project based on aurdino controller and domain specific training called ADAS data capturing and processing algorithms for various live v AUTOSAR (AUTomotive Open System ARchitecture) is an open and standardized automotive software architecture, jointly developed by automobile manufacturers, suppliers and tool developers. The test questions were based on quantitative aptitude, logical reasoning, basics of C, microcontroller, analog electronics, and 2 coding questions. What is Factless fact table? This is very important interview question. If you are looking for a job and want to work on some of fast growing startups or future-proof and established businesses then check out our jobs for C++ developer.The board of directors of KPIT has approved the acquisition of an initial 25% shareholding in FMS. With this information at hand you should be well prepared for your job interview as a C++ developer. For example, the factorial of four would be: (one*two*three*four) The factorial is calculated by multiplying consecutive integers, starting with one and ending at n. Write a program to calculate the factorial of an integer. Write a program to calculate the square root of an integer The benefit of this can be seen in the following example:Ĭlass m圜lass
It's important because it prevents access to data that may not be intended for public use, while still allowing other code outside the object itself to interact with those same functions. What is encapsulation?Įncapsulation is the process of containing or bundling data and functions together into a single unit. ::end - refers to the namespace that is below this one, or equivalently ns::ns_var in C++ and "ns" : "inner" in XML. ::begin - refers to the namespace directly above the current level, or equivalently in XAML. There are two other forms of the scope resolution operator: In this example, we would be referring to "ns::inner". Then, the scope resolution operator allows us to access outer_var without having to specify its namespace: ::outer::inner. The scope resolution operator allows access to names that are declared in an outer block without having to explicitly specify their namespace. Explain what is meant by 'scope resolution operator' or ::?
This means that when you use a c++ string, if someone has to copy it or change its content, he/she will only have to make a deep copy of the string, while with std::string you will need to make a full copy. The main advantage is in how they're implemented: a vector of characters vs an internal representation. What are the advantages of using c++ strings over std::strings? A std::basic_string represents its content using a vector of characters, while a c++ string holds them inside themselves as part of the string object. The main difference is in how they're implemented. The simple answer would be that both are containers for character strings. What is the difference between a c++ string and an std::string? The most common implementation of this template in C++11 and onward is called std::basic_string or just "basic_string". It supports basic operations such as: concatenation, comparison and iterators.
The std::string is a templatized container for character strings. Knowing the right questions and answers can make or break your chances of getting the position.īelow are some of the most common interview questions asked in c++ programming interviews and their answers. If you are a c++ programmer, then you know how important it is to be prepared for job interviews.
