c++ - The difference between 0 and '0' in array -


i have question array initialization

what difference between

char a[6]={0};

and

char a[6]={'0','0','0','0','0','0'};

how compiler interpret above 2 expression? same or not??

'0' ascii character number 0. value 48.

the constant 0 zero byte or null byte, written '\0'.

these 4 equivalent:

char a[6] = {0}; char a[6] = {0, 0, 0, 0, 0, 0}; char a[6] = {'\0', '\0', '\0', '\0', '\0', '\0'}; char a[6] = "\0\0\0\0\0"; // sixth null byte added automatically compiler

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
