c++ - character printing confusion -


i have code:

#include <iostream> #include <string> using namespace std; int main(){     char abc [20] = "hello hello hi";     char* ptr = abc;     cout << (abc+3); return 0;

}

why print out third character , not third character?

-edit- whoever flagged down. it's not same prinf(), same type of concept. didnt know nuances

to understand why, have understand bit of pointer arithmetic.

abc same &abc[0] , (abc + 3) same &abc[3]

that being said, cout prints string given char * null character.

therefore, printing string starts @ third character end of string. if wanted print third character, dereference pointer third character this.

 *(abc + 3)

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.
