c++ - Why doesn't this code compile - 


#include <iostream> #include<iomanip> using namespace std;  int main() {     const int numrows=3;      const int numcols=4;     int i,j;      int val[numrows][numcols]={8,16,9,52,27,6,14,25,2,10};//multiply each element 10 , display      cout<<"\ndisplay or multiplied elements";      for(i=0; i<numrows;i++)     {         val[i][j]=val[i][j]*10;     }//end of inner loop     }//end of outer loop     cout<endl;      return 0;      }

these errors received. have done wrong 16:5: error: 'cout' not name type 17:5: error: expected unqualified-id before 'return' 18:5: error: expected declaration before '}' token

you're missing inner loop , cout after double loop missing second carrot. should this:

int main() {     const int numrows=3;      const int numcols=4;     int i,j;      int val[numrows][numcols]={8,16,9,52,27,6,14,25,2,10};//multiply each element 10 , display      cout<<"\ndisplay or multiplied elements";      for(i=0; i<numrows;i++)     {         for(j=0; j<numcols;j++)         {             val[i][j]=val[i][j]*10;         }//end of inner loop     }//end of outer loop     cout<<endl;      return 0;  }

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.
