Which is the fastest way to get a slice of an array in c? -


i this:

char in[] = {'a','b','c','d','f','r','t','b','h','j','l','i'};  char out[3];  out = ∈

and first 3 characters

but error of incompatible types

out array name, can't modified. there's no straight forward way slice of array in c. can use memcpy:

memcpy(out, in, sizeof out);

and need take in has sufficient elments copy from.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
