What is the difference between printf() and puts() in C?

Question

I know you can print with printf() and puts(). I can also see that printf() allows you to interpolate variables and do formatting.

Answer 1

int puts(const char *s);

puts() writes the string s and a trailing newline to stdout.

int printf(const char *format, ...);

The function printf() writes output to stdout, under the control of a format string that specifies how subsequent arguments are converted for output.

I'll use this opportunity to ask you to read the documentation.
