r - How to exit loop when there's an error -


i have loop in search value in matrix. when no such value exits, function throw error. want exit loop when error occurs. how do this?

i'm thinking this, not sure how execute in r.

for (i in 1:n){ val<-#find value in matrix if (val returns error) break }

thanks!

you can indeed do:

vec = c(1,2,3,5,6)  for(u in 1:10){      if(!is.element(u, vec))      {          print(sprintf("element %s not found in vec", u))           break      }      print(sprintf("element %s found in vec", u)) }  #[1] "element 1 found in vec" #[1] "element 2 found in vec" #[1] "element 3 found in vec" #[1] "element 4 not found in vec"

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.
