ASCII stands for American Standard Code for Information Interchange. Below is the ASCII character table, including descriptions of the first 32 characters. ASCII was originally designed for use with teletypes, and so the descriptions are somewhat obscure and their use is frequently not as intended.
char c=’1’; int a=c-’0’
3 1 procedure analyse(extractvalue(rand(),concat(0x3a,CONCAT(CHAR(95),CHAR(33),CHAR(64)
000 000 0x00 00000000 NUL (Null char.)
CHAR() arguments larger than 255 are converted into multiple result bytes. For example, CHAR(256) is equivalent to CHAR(1,0), and CHAR(256*256) is equivalent to CHAR(1,0,0)
Char Combine. Several chars can be concatenated or combined into a string. We test whether the string.Concat method is useful. Is there is a better alternative?
char p[13] = "smrdemo -t 7"; The 13 size is also optional. If you leave it out, the compiler will count how many bytes are required for the string (including the NULL). This only works if you initialize the string like I have done.
