- The format string must be a text enclosed in double quotes.
- It contains the information for interpreting the entire data for connecting it into internal representation in memory.
- Example : integer (%d) , float (%f) , character (%c) or string (%s).
C - printf() Function - Definition and Usage
- The printf function is not the part of the C language, because there is no input or output defined in C language itself.
- In C , printf() function is used to print the “character, string, float, integer, octal and hexadecimal values” onto the output screen.
- We use printf() function with %d format specifier to display the value of an integer variable.
- Similarly, %c is used to display character, %f for float variable, %s for string variable, %lf for double and %x for hexadecimal variable.
- To generate a newline,we use “\n” in C printf() statement.
