| printf: display message by format |
|
|
//Header file: #include <stdio.h>
//Declaration: int printf(const char *format, ...);
//Return: the number of characters actually printed. A negative value indicates failure.
// The printf() Format Specifiers
//Code Format
//%a: Hexadecimal output in the form 0xh.hhhhp+d (C99 only).
//%A: Hexadecimal output in the form 0Xh.hhhhP+d (C99 only).
//%c: Character.
//%d: Signed decimal integers.
//%i: Signed decimal integers.
//%e: Scientific notation (lowercase e).
//%E: Scientific notation (uppercase E).
//%f: Decimal floating point.
//%F: Decimal floating point (C99 only; produces uppercase INF, INFINITY, or NAN when applied to infinity or a value that is not a number. The %f specifier produces lowercase equivalents.)
//%g: Uses %e or %f, whichever is shorter.
//%G: Uses %E or %F, whichever is shorter.
//%o: Unsigned octal.
//%s: String of characters.
//%u: Unsigned decimal integers.
//%x: Unsigned hexadecimal (lowercase letters).
//%X: Unsigned hexadecimal (uppercase letters).
//%p: Displays a pointer.
//%n: The associated argument must be a pointer to an integer. This specifier causes the number of characters written (up to the point at which the %n is encountered) to be stored in that integer.
//%%: Prints a percent sign.
#include <stdio.h>
int main(void){
printf("Hi %c %d %s", 'c', 10, "there!");
