C Cheatsheet: Specifiers

Cheatsheet: printf Specifiers

The order-matter pair in C.

Specifier	Type
%d	int
%ld	long int
%f	float / double (print)
%c	char
%s	string (char[])
%p	pointer
%.2f	float with 2 decimals
%e	scientific notation

Example

printf("%d and %.2f\n", 10, 3.14159);
// 10 and 3.14

Scanf hints

scanf needs a pointer, so write.

TL;DR

Match the specifier to the type exactly.
%.2f = two decimals.
scanf requires & to write into a variable.
