Cognizant Interview Coding Questions 

Recently, Cognizant modified the way it hires employees. The online test offered by Cognizant through AMCAT now has a new component entitled "Automata fix questions." 

Therefore, it is advised that you review the Cognizant placement test questions from previous years before your exam.

Here, we have listed a few probable questions that may be put forward in the technical round to you by the interviewer.

 

1) How do data types operate?

Answer: Data Type describes the kind of value we assign to a variable and the range of values we assign between them. For instance, the C data type "Int" may hold values between "-32768 and +32768."

 

2) Which of the following should be used to increase the value by 1? a++ or a = a+1?

Answer: a++ because we know it is an internal single-machine instruction (INC).

 

3) Lvalue and rvalue: what are they?

Answer: Rvalue refers to the expression appearing to the assignment operator's right. An lvalue, which can be seen on the left of the assignment operator, is given the value attached to the value. The value ought to refer to a variable rather than a constant.

 

4) What does "compilation" mean?

Answer: Compilation is the process of converting high-level source code into low-level machine code. Compiler software is used to perform the compilation. If the source code is free of syntactical or structural mistakes, the compiler generates object code with the extension .obj (in Windows) or .o (in Linux) and outputs it.

 

5) What distinguishes far pointers from near pointers?

Answer: They are non-standard keywords, first and foremost. Only 215 of the memory may be accessed by a close pointer, but a far pointer can access 232. Both of the keywords are non-standard and implementation-specific.

 

6) How do the C memcpy() and strcpy() methods differ from one another?

Answer: To copy a specific number of bytes from one memory to another, use the memcpy() method. As opposed to this, the strcpy() function copies the contents of one string into another. The memcpy() function manipulates memory instead of values. Strcpy(), however, operates on values rather than memory.

 

7) What distinguishes a variable definition from a variable declaration in C?

Answer: The compiler receives information about a variable's data type and size from the declaration. Variable declaration, however, allots RAM to the variable. In a programme, variables can be declared many times. However, defining a variable in a programme can only take place once. Assignment of properties and identification to a variable are done through variable declaration. On the other hand, a variable definition governs the allocation of storage space for a variable.

 

8) In C, what is an enum?

Answer: A data type known as an enumeration consists of a list of named integer constants. The value is initially set to 0 (zero) for the consecutive identifiers in the list, then increased by 1 by default.

 

9) Dangling pointers: what are they?

Answer: A pointer that originally holds a valid address but eventually releases or frees the address. As a result, a pointer like that is referred to as 'dangling'.

 

10) What does a C const pointer do?

Answer: A constant pointer cannot alter the address of the variable it points to. Constant pointers can only point to one variable at a time; they cannot be changed to point to another variable. The Const pointer is the name of this pointer.
