using dynamic arrays in C code example
Example 1: c array initialization
int x[] = {1,2,3}; // x has type int[3] and holds 1,2,3
int y[5] = {1,2,3}; // y has type int[5] and holds 1,2,3,0,0
int z[3] = {0}; // z has type int[3] and holds all zeroes
Example 2: how to make a n*n 2d dynamic array in c++
int** a = new int*[rowCount];
for(int i = 0; i < rowCount; ++i)
a[i] = new int[colCount];
