c - How does below method of array intialization differ in context to array bounds checking? -


why int arr[2]={10,20,30,40,50} leads error? why can't initialization escape error array bound checking?

int arr[2] ; arr[0]=10, arr[1]=20, arr[3]=30, arr[4]=40;

doesn't cause error in context c language array bound checking ?

there no runtime array bounds check in c. free obliterate whatever in memory. 1st example show, compile-time structure, compiler know declared array of size 2, , initialization has > 2 elements.

(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...
