array 2d code example
Example 1: 2d array
int a[2][3]= {
{1, 2, 3},
{4, 5, 6}
};
cout << a[1][1]; // Output is 5
Example 2: c fill 2d array
// Either
int disp[2][4] = {
{10, 11, 12, 13},
{14, 15, 16, 17}
};
// Or
int disp[2][4] = { 10, 11, 12, 13, 14, 15, 16, 17};
// OR
int i, j;
for (i = 0; i < HEIGHT; i++) { // iterate through rows
for (j = 0; j < WIDTH; j++) { // iterate through columns
disp[i][j] = disp[i][j];
}
}
Example 3: how to get a rectangular grid out of two given one-dimensional arrays
import numpy as np
np.meshgrid(list1, list2)
