As a little more comprehensive example I'd like to summarize the syntax in this way: // declaring and initialize a 1D integer array int arr1 [4] = {1, 2, 3, 4}; // declaring and initialize a 2D integer array int arr2 [2][3] = { {1, 2, 3}, {4, 5, 6} }; // declaring and initialize a 3D integer array int arr3 [2][3][4] = { { {1, 2, 3, 4}, {5, 6, 7, 8}, {9,10, 11, 12} }, { {13,14,15,16}, {17,18, 19, 20}, {21,22,23,24} } }; ///////////////// Accessing to each element of array: // for 1D arr1[0] = 10; arr1[1] = 20; arr1[2] = 30; arr1[3] = 40; // for 2D arr2[0][0] = 10; arr2[0][1] = 20; arr2[0][2] = 30; arr2[1][0] = 40; arr2[1][1] = 50; arr2[1][2] = 60; // for 3D arr3[0][0][0]; // 1 arr3[0][0][1]; // 2 arr3[0][0][2]; // 3 arr3[0][0][3]; // 4 arr3[0][1][0]; // 5 arr3[0][1][1]; // 6 arr3[0][1][2]; // 7 arr3[0][1][3]; // 8 arr3[0][2][0]; // 9 arr3[0][2][1]; // 10 arr3[0][2][2]; // 11 arr3[0][2][3]; // 12 arr3[1][0][0]; // 13 arr3[1][0][1]; // 14 ....

one dimensional would be like arr['1'] two dimensional would be like arr['2']['accounts'] arr['2'] is an array in this example not a variable

Try one dimension: int d1[] = {1, 3 ,4}; two dimensions int d2[,] = {2,49,596} , {63,84, 64};
