C is one of the high level languages. It is a general purpose language, which means it can be used to write programs of any sort.
Job Interview Questions & Answers
What are the features of C Languages? It is a general purpose programming language.
It is usually called system programming language but equally suited to writing a variety of applications. It supports various data types 4. It follows the programming style based on fundamental control flow constructions for structured programming 5. What does static variable mean? Static variables are the variables which retain their values between the function calls.
C Programming Interview Questions
They are initialized only once their scope is within the function in which they are defined. What is a pointer? Pointers are variables which stores the address of another variable.
That variable may be a scalar including another pointer , or an aggregate array or structure. The pointed-to object may be part of a larger object, such as a field of a structure or an element in an array. What are the uses of a pointer? Therefore, when a variable is declared, the program knows the data type of that variable.
In case of function declaration, the program knows what are the arguments to that functions, their data types, the order of arguments and the return type of the function.
Therefore, we can think of definition as a super set of declaration. What are different storage class specifiers in C? What is scope of a variable?
How are variables scoped in C? Scope of a variable is the part of the program where the variable may directly be accessible. In C, all identifiers are lexically or statically scoped. See this for more details.
When should we use pointers in a C program? To get address of a variable 2. For achieving pass by reference in C: Pointers allow different functions to share and modify their local variables. It is used to assign a value to a given variable.
The modulus operator outputs the remainder of a division. A nested loop is a loop that runs within another loop. Put it in another sense, you have an inner loop that is inside an outer loop.
In this scenario, the inner loop is performed a number of times as specified by the outer loop. For each turn on the outer loop, the inner loop is first performed.
Compilers and interpreters often deal with how program codes are executed. Interpreters execute program codes one line at a time, while compilers take the program as a whole and convert it into object code, before executing it.
The key difference here is that in the case of interpreters, a program may encounter syntax errors in the middle of execution, and will stop from there. On the other hand, compilers check the syntax of the entire program and will only proceed to execution when no syntax errors are found.
The char keyword can only hold 1 character value at a time. By creating an array of characters, you can store string values in it. While curly brackets are mainly used to group several lines of codes, it will still work without error if you used it for a single line. Some programmers prefer this method as a way of organizing codes to make it look clearer, especially in conditional statements.
Header files are also known as library files.
C Interview Question Answers
They contain two essential things: the definitions and prototypes of functions being used in a program. Simply put, commands that you use in C programming are actually functions that are defined from within each header files. Each header file contains a set of functions.
For example: stdio. Syntax errors are associated with mistakes in the use of a programming language.So, it will ignore the startup directive and will produce no error. So just feel confident during your interview.
We need to compare element by element of the structure variables. The first argument which contains strings to be printed or format specifiers is mandatory. One thing to note is that you cannot pass the entire array to a function. Passing base address will give access to the whole array.
