Write a CPP program to find transpose of 2D matrix and allocate memory dynamically to the matrix using dynamic memory allocation. When you declare a variable using a basic data type, the C compiler automatically allocates memory space for the variable in a pool of memory called the stack.. For example, a float variable takes typically 4 bytes (according to the platform) when it is declared. // Dynamically Allocate Memory for 2D Array, // dynamically allocate memory of size M*N, // dynamically create array of pointers of size M, // dynamically allocate memory of size N for each row, // dynamically allocate memory of size M*N and let *A point to it, // position allocated memory across M pointers, Notify of new replies to this comment - (on), Notify of new replies to this comment - (off). Write a Program to generate Fibonacci Series by using Constructor to initialize the Data Members. Once done with the array, we can free up the memory using the delete operator. In other words, dynamic memory Allocation refers to performing memory management for dynamic memory allocation manually. That said you usually want to have dynamic sizes or your matrix may be larger than the stack limit. Below diagram shows how above method of memory allocation works in the case of 3X2 matrix array. This means that a memory block of size row*column*dataTypeSize is allocated using malloc and pointer arithmetic can be used to access the matrix elements.
