Input string size output by asc value

The input string is output according to the asc value-General Linux technology-Linux programming and kernel information. The following is a detailed description. Programming Language c
# Include
# Include
Char * sort (char * s)
{
Int I, j, lenth;
Char temp;
Lenth = strlen (s );

For (j = 0; j For (I = 0; I If (* (s + I)> = * (s + I + 1 ))
{
Temp = * (s + I );
* (S + I) = * (s + I + 1 );
* (S + I + 1) = temp;
}



Return s;
}



Int main ()
{
Char str1 [500] = {0 };


Printf ("please input some characters :");
Gets (str1 );

Sort (str1 );
Printf ("ASC number small to big: % s", str1 );
Printf ("\ n ");
}

Knowledge Point: function call bubble sorting
Note: The characters can be compared with each other.
Appendix: Although Tan Haoqiang's c also has the bubble method, the program in the book is flawed for (I = 0; I Compiling with gcc in ubuntu may cause errors.
