In C language:

1. Implement function int *create_dyn_array(unsigned int n) that allocates an int array for n integers. n is given as argument to the function when it is called. After allocating the array, the function should read the given number of integers to the array from user, using the scanf function. After the right amount of integers have been read, the function returns pointer to the dynamically allocated array.

2. Implement function int *add_dyn_array(int *arr, unsigned int num, int newval) that adds a single integer to the existing dynamically allocated array of integers (arr). The length of the existing array is num, and the new integer to be added is given in parameter newval. Youll need to ensure that array is extended to hold the additional integer. Check that the function works correctly when called several consecutive times.
