Dear Masters

Why my shellcode is trunced after "\x20" opcode, when it is copied by string to stack on a second vulnerable program?

--cmd.exe-- char shell[]=

"\xc7\x44\x24\x0c\x65\x78\x65\x20" <---only this line is put in stack, though hv a enough space "\xc7\x44\x24\x08\x63\x6d\x64\x2e" "\x31\xc0" "\x89\x44\x24\x04" "\x8d\x44\x24\x08" "\x89\x04\x24" "\x8d\x05\xad\x23\x86\x7c" "\xff\xd0"; --end shell--
