Description / Tips

[O Sample 1 Description] title a total of 3 characters, these 3 characters are numeric characters.

[O Sample 2 illustrates] the title a total of 5 characters, including 1 uppercase letters, 1 lowercase letters and 2 numeric characters, and 1 spaces. Because spaces are not included in the result, the effective number of characters so the title is 4 Ge. 

[Data Size and agreed]

Predetermined | s | denotes the string s length (i.e., the character string and the number of spaces). 
For 40 % of the data, . 1 ≤ | S | ≤ . 5 , to ensure that the input line and the end line breaks numeric characters. 
For 80 % of the data, 1 ≤ | S | ≤ 5 , the input may only contain upper and lower case letters, numeric characters and the end of the line newline. 
For 100 % of the data, . 1 ≤ | S | ≤ . 5 , the input may include upper and lower case letters, numeric characters at the end, the line spaces and line breaks.

Code

#include <the iostream> 
#include <cstdio> // GET () library function where 
#include <CString> // strlen () library function where 
the using  namespace STD;
 int main () 
{ 
    int SUM = 0 ;
     char A [ . 11 ]; // C-style string 
    the gets (A); // use gets () function reads 
    for ( int I = 0 ; I <= strlen (A) - . 1 ; I ++) IF (A [I] =! '  ' ) SUM ++; // iterate 
    cout << SUM; // output answers
    return 0;
}
