Formatted Input and Output

Formatted input and output (formatted I/O) is a technique for presenting data in a specific format, such as text, numbers, or images, to the user. This allows users to input and output data in a structured and organized manner, making it easier to process and understand.

Example:

#include <stdio.h>

int main() {

int number;

// Print the prompt to the user

printf("Enter a number: ");

// Read the user's input

scanf("%d", &number);

// Print the formatted number

printf("You entered: %d\n", number);

return 0;

}

Explanation:

printf() function is used to print a prompt to the user.
scanf() function is used to read the user's input and stores it in the number variable.
printf() function is called again with the formatted string "You entered: %d".
The %d format specifier is used to indicate that the number variable should be printed as a decimal number.

Benefits of Formatted I/O:

Human-readable output: Users can easily understand the format of the data.
Improved data clarity: Formatting helps to organize data and make it easier to process.
Reduced cognitive load: Users do not have to decode the data format, reducing cognitive load.
Enhanced user experience: Formatted I/O makes the interaction more intuitive and user-friendly
