C Programming Concepts

What are the basic data types in C programming?

• int, char, float, double

• bool

• void

• string

Explain the difference between 'if' and 'switch' control structures in C using a real-world scenario.

• 'if' is used for making decisions based on individual preferences

• The main difference between 'if' and 'switch' control structures in C is that 'if' is used for making decisions based on specific conditions, while 'switch' is used for making decisions based on multiple conditions.

• 'switch' is used for making decisions based on a single criterion

• 'if' and 'switch' are used interchangeably in C

What is the purpose of functions in a software development project? How is scope defined in the project?

• Functions in the project are used for defining data types, while scope in the project determines the order of execution.

• Functions in the project are used for input/output operations, while scope in the project determines the program's entry point.

• Functions in the project are used for error handling, while scope in the project defines the memory allocation.

• Functions in the project are used for encapsulating code, while scope in the project defines the visibility and accessibility of variables.

How are pointers used in a computer science project? Explain the concept of memory allocation.

• Pointers in a computer science project are used to store memory addresses and facilitate memory manipulation. Memory allocation involves requesting memory during program execution to store data, which can be done statically or dynamically using functions like malloc, calloc, realloc, and free.

• Pointers in a computer science project are only used for accessing pre-defined memory locations.

• Memory allocation involves using built-in keywords like 'new' and 'delete'.

• Pointers in a computer science project are used to perform arithmetic operations on data directly.

What is the difference between traditional classrooms and online classes?

• Traditional classrooms require physical attendance, while online classes can be attended remotely.

• Traditional classrooms involve face-to-face interaction, while online classes rely on virtual communication.

• Traditional classrooms have fixed schedules, while online classes offer flexibility in timing.

• Traditional classrooms use physical textbooks, while online classes utilize digital resources.

What is the capacity of a 'standard' coffee cup?

• 8 ounces

• 12 ounces

• 16 ounces

• 20 ounces

How do you declare a character variable in a programming language?

• int myChar;

• char myChar = 'A';

• char myCharacter;

• char myChar;

What is the syntax for a 'for' loop in C when calculating the total number of apples picked by Shreya, Kavya, and Vanya?

• for(initialization; condition; increment/decrement) {}

• for(initialization; condition; increment/decrement) ;

• for(initialization; condition; decrement) {}

• for(initialization; condition; increment) {}

Explain the concept of pass by value and pass by reference in function arguments using a real-world scenario.

• Pass by value involves passing a copy of the actual value to the function, while pass by reference involves passing a reference to the actual value.

• Pass by value involves passing a reference to the actual value.

• Pass by value involves passing the memory address of the actual value.

• Pass by reference involves passing a copy of the actual value to the function.

How do you dynamically allocate memory in C using 'malloc'?

• Include header file and use malloc function

• Specify the data type along with the number of bytes needed

• Include header file and use malloc function by specifying the number of bytes needed.

• Use 'calloc' function instead of 'malloc'
