Final answer:
In C programming, printf format specifiers determine how to format and display different data types using the printf function. They include %c for characters, %d and %i for signed integers, %e for scientific notation, %f for floating-point, %n for storing the output count, %o for octals, %s for strings, %u for unsigned integers, %x for hexadecimal numbers, and %% for a literal percent sign.
Step-by-step explanation:
In C programming, the printf format specifiers are used to define how various data types are displayed when using the printf function. Each specifier corresponds to a certain data type or print method:
- %c - Represents a single character.
- %d - Represents a signed decimal integer.
- %e - Represents scientific notation (e.g., 1.2e+2).
- %f - Represents floating-point notation.
- %i - Represents a signed integer (identical to %d).
- %n - The associated argument must be a pointer to an integer where the number of characters written so far is stored.
- %o - Represents an unsigned octal (base 8) number.
- %s - Represents a string of characters.
- %u - Represents an unsigned decimal integer.
- %x - Represents an unsigned hexadecimal (base 16) number, using lowercase letters for 10-15.
- %% - Represents a literal percent sign (%).
These specifiers are essential in formatting output strings correctly in C programming to represent different types of data.
