Printf() and scanf in c

In C, scanf is a function that stands for Scan Formatted String. It is the most used function to read data from stdin (standard input stream i.e. usually keyboard) and stores the result into the given arguments.

Printf in c

It can accept character, string, and numeric data from the user using standard input. It also uses format specifiers like printf.

Example:

Input

Output

Explanation: In this example, scanf(“%d”, &n) reads an integer from the keyboard and stores it in the integer variable n.

The %d format specifier indicates that an integer is expected, and &n provides the memory address of n so that scanf can store the input value there.

scanf Syntax

The syntax of scanf() in C is similar to the syntax of printf().

scanf(“format”, address_of_args… );

Here,

• format: It is the format string that contains the format specifiers(s).
• address_of_args: Address of the variables where we want to store the input.

We use & operator to find the address of the variables
