printf() and scanf() in C: Understanding Input and Output

Short summary

C's printf() outputs formatted data to screen while scanf() reads user input into memory using the & operator to specify storage address. The tutorial covers format specifiers (%d, %f, %c, %s), common mistakes, and a data-flow mental model: keyboard → scanf → memory → printf → monitor. Essential foundation for C beginners.

• •printf() displays formatted output; scanf() reads input using & operator for memory addresses
• •Format specifiers determine how data types are interpreted and displayed
• •Data flow model (keyboard → memory → display) aids understanding pointers and memory management
