printffunction is used to display formatted output to the console. - It allows developers to control the appearance of the output by using format specifiers.
Format Specifiers
-
%dis used to print integer values.
The scanf Function
- The
scanffunction is used to read data from the console and store it in variables. - It acts as an input tool for the program.
Character Input with scanf
-
scanf("%c", &characterVariable);is a correct declaration to read a character from the user and store it incharacterVariable.
Handling Mismatched Input
- If the user enters a value that doesn't match the expected type in
scanf(e.g. entering characters when expecting an integer), the function might not assign the input to the variable, leading to unexpected program behavior. - The function might also return a value indicating that the input was invalid.
