what is the meaning of printf in c programming
printf format string "Printf" is the name of the most-used C output function, and stands for "print formatted". Printf format strings are complementary to scanf format strings, which provide formatted input (parsing). In both cases these provide simple functionality and fixed format compared to more sophisticated and flexible template engines or parsers, but are sufficient for many purposes.
C (programming language) C (/siː/, as in the letter c) is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, and therefore it has found lasting use in applications that had formerly been coded in assembly language, including operating systems, as well as various application software for computers ranging from supercomputers to embedded systems.
typedef typedef is a reserved keyword in the C and C++ programming languages. It is used to create an alias name for another data type.[1] As such, it is often used to simplify the syntax of declaring complex data structures consisting of struct and union types, but is just as common in providing specific descriptive type names for integer data types of varying lengths. The C standard library and POSIX reserve the suffix '_t', for example as in size_t and time_t.
Len (programming) In Python, len() can be used to denote the length of a string:
