Question

Array processing Create a program that processes two-dimensional array according to task variant Additional requirements 1. 2. 3. 4. Input dimensions of array form keyboard (use dynamic memory allocation) Fill array with random numbers in range R. Processing of array should be implemented as function (using indices). Displaying the content of array should be implemented as function (using pointers) 5 12 8 2 8 3 3 16 1 22 215 34 0 11 88 13 22 6 5 81 76 23 56 118 5. 6. Program should output text message in case of errors. Program has to be written in C or C++ Task variants Last digit of number of Task student card 0 or 1 Define 3 smallest elements in array and their indices (number of row and column 100. 50
