Which of the following function is more appropriate for reading in a multi-word string?ans.puts()scanf()gets()printf() Previous Marked for Review Next

In this case, the question is about which function is best suited for reading a multi-word string in C programming language. Each of the options provided serves a distinct purpose, so let’s analyze them in detail:

1. ans.puts(): This function is typically used to output strings to the console. It is not suitable for reading input.

2. scanf(): This function can be used to read formatted input from standard input. However, when reading strings, it stops at whitespace, which means it can only read a single word at a time.

3. gets(): This function is designed to read an entire line of input, including spaces. However, it is considered unsafe because it does not perform bounds checking and can lead to buffer overflow issues.

4. printf(): This function is primarily used for output, similar to puts(). It does not read input.

Given this analysis, gets() is the most suitable for reading a multi-word string, but it should be noted that due to safety concerns, it is advised to use safer alternatives such as fgets() which allows you to limit the number of characters read and avoid buffer overflow.

Conclusion

Among the options provided, while gets() can read a multi-word string, it is recommended to use fgets() for better safety and control.
