In C language, which of the following functions can not used to write data to a file?Select one or more:a.putsb.getsc.fprintfd.fputce.fputs

To determine which functions in the C programming language cannot be used to write data to a file, we need to analyze the provided options. Here is a brief explanation of each:

1. puts: This function is used to write a string to the standard output (stdout). While it writes to an output stream, it does not directly write to a file unless the file is redirected to stdout. Therefore, in its typical usage, it cannot be used to write data to a file by itself.

2. get: This option appears to be incomplete or incorrect as get is not a standard C function for writing data. There is a getc() function, which is used for reading data. Thus, this would not be used for writing data to a file.

3. fprintf: This function is used to write formatted output to a specified file stream. It is specifically designed for writing data to files, so it can definitely be used for that purpose.

4. fputc: This function writes a single character to a specified file stream. It is a valid function to use for writing to files.

5. fputs: This function is used to write a string to a specified file stream. It is another valid function for writing to files.

Final Answer

Based on the analysis, the functions that cannot be used to write data to a file are puts and get.
