printf is a generic print function that takes 100 different format specifiers and prints the appropriate result string. putchar , well, puts a character on the screen. … Back to the question: use putchar to print a single character. Again, it’s probably a lot faster.
What is the difference between putchar and put function?
putchar is short for PUT CHARACTER while puts is short for PUT STRING. As the name suggests, putchar is used to print a single character to console or standard output, while puts prints a string with an extra newline character at the end. It is used to write a line to standard output. 16

puts() writes the string s and a final newline to stdout. int printf (const char *format, …) The printf() function writes output to stdout, controlled by a format string that specifies how subsequent arguments are converted for output. 29
What is the difference between PUTC() and putchar()?
The description. The putc() function converts c to an unsigned character and then writes c to the output stream at the current position. putchar() is equivalent to putc(c, stdout) . The putc() function can be defined as a macro so that the argument can be evaluated multiple times.
What is the difference between scanf and getchar?
The main difference between scanf and getchar is that scanf is a formatted way of reading keystrokes while getchar reads a single character from the keyboard. 22

IS sets faster than printf?
The main difference is that printf() is a fairly advanced generalization of string output, while puts is a simple string printing function that outputs its argument and a newline character. It’s worth mentioning that puts() is usually a bit faster than printf(), which has to interpret its format string.
