Hello Every body
My question is very simple for you all experts, as I am learning how to write C++ program. I need a code for summing up the 4 corner of 2D array in turbo C++.
Thank you all with regards
Hello Every body
My question is very simple for you all experts, as I am learning how to write C++ program. I need a code for summing up the 4 corner of 2D array in turbo C++.
Thank you all with regards
In a M by N array, where M is the number of rows and N is the number of columns, the array has these coordinates
Upper left: 0,0
Lower left: (M-1),0
Upper Right: 0,(N-1)
Lower Right: (M-1),(N-1)
The way I understand your assignment is to find the sum of those four cells.
#include <iostream>
#include <iomanip>
int main()
{
srand(time(NULL));
const int a=5;
const int b=5;
int arr[a][b];
for(int i=0; i<a; i++){
for(int j=0; j<b; j++){
arr[i][j] = rand()%9+1;
std::cout << std::setw(4) << arr[i][j];
}
std::cout << "\n";
}
std::cout << "\n";
std::cout << "corner: " << arr[0][0] << " " << arr[a-1][0] << " " << arr[0][b-1] << " " << arr[a-1][b-1] << "\n\n";
std::cout << "cornerSum=" << ( arr[0][0] + arr[0][b-1] + arr[a-1][0] + arr[a-1][b-1] ) << "\n\n";
system("PAUSE");
return 0;
}
Thanks for doing his homework for him.
