Write program that uses a function named cointoss that simulates the tossing of a coin. when you call the function, it should generate a random number in the range of 1 through 2. if the random number is 1, the function should display “heads”. if the random number is 2, the function should display “tails”. demonstrate the function in a program that asks the user how many times the coin should be tossed, then simulates the tossing of the coin that number of times.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
