c++ - Why does this recursive function crash? -

c++ - Why does this recursive function crash? - int g(int n) { int x = g(n - 1); if (x > 0) { homecoming x + 1; } else { homecoming 1; } } my guess has first line of function... i'm not sure why case. if function said this: int g(int n) { homecoming g(n - 1); } then not expect work, instead maintain recursing until run out of stack space , programme crashes. putting recursion before exit status in function, doing this. you should rewrite function performs exit test before calling g() again. c++ crash segmentation-fault
