key point

scanf 中 int、long、float、double 前後的空白、換行，會被自動忽略。
scanf 中 string s、char c 前後的空白、換行，不會被忽略，需要自己比對計算，因為這些也算是字元。

Some C++ data types, their format specifiers, and their most common bit widths are as follows:

• Int ("%d"): 32 Bit integer
• Long ("%ld"): 64 bit integer
• Char ("%c"): Character type
• Float ("%f"): 32 bit real value
• Double ("%lf"): 64 bit real value

Reading
To read a data type, use the following syntax:
scanf("'formatspecifier'", &val)

For example, to read a character followed by a double:
char ch;
double d;
scanf("%c %lf", &ch, &d);

For the moment, we can ignore the spacing between format specifiers.

Printing
To print a data type, use the following syntax:
printf("\formatspecifier\", val)

For example, to print a character followed by a double:
char ch = 'd';
double d = 234.432;
printf("%c %lf", ch, d);

Note: You can also use cin and cout instead of scanf and printf; however, if you are taking a million numbers as input and printing a million lines, it is faster to use scanf and printf.

Input Format
Input consists of the following space-separated values: int, long, char, float, and double, respectively.

Output Format
Print each element on a new line in the same order it was received as input. Note that the floating point value should be correct up to 3 decimal places and the double to 9 decimal places.

Sample Input
3 12345678912345 a 334.23 14049.30493

Sample Output
3
12345678912345
a
334.230
14049.304930000

Explanation
Print int 3,
followed by long 12345678912345,
followed by char a,
followed by float 334.230,
followed by double 14049.304930000.
