Learn and Master C Programming - Using 'sprintf' function

The video tutorial introduces the sprintf function in C programming, explaining its purpose and usage. It highlights the security concerns associated with sprintf, such as buffer overruns, and discusses its deprecation. The tutorial provides alternatives and solutions for handling deprecated functions and string assignments in C. It also covers the secure version of sprintf, emphasizing the importance of specifying buffer sizes to prevent security issues.

What is the primary difference between printf and sprintf?

• printf is faster than sprintf

• printf is deprecated, sprintf is not

• printf prints to the screen, sprintf stores in a string

• printf is for integers, sprintf is for strings

Why is it important to ensure the buffer size is sufficient when using sprintf?

• To prevent buffer overflow

• To ensure compatibility with all compilers

• To increase execution speed

• To reduce memory usage

What is a major reason for the deprecation of sprintf?

• It is not compatible with modern compilers

• It does not support floating-point numbers

• It is too slow

• It can cause buffer overruns

What additional parameter does sprintf_s require compared to sprintf?

• The output file

• The format string

• The number of arguments

• The buffer size

Why can't you assign a string directly to a char array after its declaration in C?

• It causes a syntax error

• The compiler does not allow it

• C does not support string assignments

• The array size is fixed at declaration

What is the advantage of using sprintf over strcpy?

• sprintf is more secure

• sprintf uses less memory

• sprintf allows formatted strings

• sprintf is faster

How can you avoid hardcoding buffer sizes in your code?

• By using dynamic memory allocation

• By using macros for array size

• By using global variables

• By using inline functions
