how to find maximum in only coloums in 2d array.?????

[Zhuge]

Iterate through.

I could help you more if you put in some effort (perhaps by showing what you've done so far).

Hi @muddaser,
as @Zhuge said you
have to iterate through
the 2D array i have
a little example for
you!

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

//2D_Array.cpp //## #include <iostream> using std::cout; using std::endl; bool isEven(int number); int main(){ int const ROW=3; int const COL=3; int bd_array[ROW][COL]={{1,2,3},{4,5,6},{7,8,9}}; cout<<"\n2D array elements"<<endl; //print array for(int i=0;i<ROW;i++){ for(int j=0;j<COL;j++){ cout<<bd_array[i][j]; }//end inner for cout<<endl; }//end outer for //find even numbers by column cout<<"\nEven numbers by column \n\n"; for(int k=0;k<COL;k++){ for(int i=0;i<ROW;i++){ if(isEven(bd_array[i][k])){ cout<<bd_array[i][k]<<" even"; }else{ cout<<bd_array[i][k]; }//end if-else cout<<'\t'; }//end inner for cout<<endl; }//end outer for return 0; //indicates success }//end of main bool isEven(int number){ if(number%2==0)return true; return false; }//end function isEven

/2D_Array 2D array elements 123 456 789 Even numbers by column 1 4 even 7 2 even 5 8 even 3 6 even 9

regards!

Of course, if it's an array you already know the maximum...>.>;; Perhaps he meant vectors?

The only way for him to know ahead of time is if it is a constant static (stack) array that is initialized.

Arrays can be modified during run time just like the STL containers.
