In the C programming language, `scanf` and `printf` are standard input and output functions used for reading input from the user and displaying output on the screen, respectively.
1. `scanf`:
Purpose: `scanf` is used for reading formatted input from the user or from a file.
Usage: You can use `scanf` to read data such as numbers, characters, or strings from the standard input (usually the keyboard) or from a file. It allows you to specify the format of the input you expect, and it stores the read values in variables.
Example: `scanf("%d", &num);` reads an integer from the user and stores it in the variable `num`.
2. `printf`:
Purpose: `printf` is used for formatted output, which means displaying data in a specific format.
Usage: You can use `printf` to display data on the screen or write it to a file. It allows you to format the output using format specifiers, which specify how variables should be represented in the output string.
Example: `printf("The value of num is %d", num);` displays the value of the variable `num` in a formatted way.
These functions are fundamental for interacting with users and displaying results in C programs. They offer control over how data is input and output, making it easier to work with different types of data and create user-friendly applications.
