c++ - segment fault when assigning a new allocated memory to a struct pointer - 


struct student { public:     string name;     string family;     string stdno;     string ncode;     float average;     float age;     struct student *fl; } *start, *cur, *p;  p = new struct student;     cur->fl = p;     p->fl = null; // p->fl = nullptr in c++11     cur = p;

i try assigning new memory allocated structure pointer,it seems there no issue segment fault when cur->fl = p; ran, doing wrong here ?

cur has not been assigned point to

cur = p;

needs before p->fl

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.
