Write a program that reads an unknown number of integers (int16_t) from the keyboard, terminated when the value (-10000) is given, and stores these into a dynamically sized array. The array should be initialised with a size to hold 10 values, and should increase in size by steps of 10 values whenever the array needs to be resized. (Note that the array should always have capacity to hold another value, for example, when it is holding 10 values the array size should be 20; the next step size up). Once it reads -10000, the program should print how many numbers it read in the format Numbers read = , then exit. The program must free() the array before exiting (but after printing the how many numbers have been read). You can use scanf("%hd", &number) to read a 16 bit integer. Note: because of the way we test this, you must not call realloc() if you just read in -10000; be efficient! For example: Input 1 2 3 4 5 -10000 Result _TESTALLOC: (calloc) Add block 0, total memblks 20 _TESTALLOC: (calloc) Total number of allocations 1, total memblks 20 Numbers read = ! _TESTALLOC: (free) Free block 0, total memblks 20 _TESTALLOC: (free) Total number of allocations 1, total memblks 0 _TESTALLOC: Total number of allocations made 1, total outstanding memblks 0

Write a program that reads an unknown number of integers (int16_t) from the keyboard, terminated when the value (-10000) is given, and stores these into a dynamically sized array. The array should be initialised with a size to hold 10 values, and should increase in size by steps of 10 values whenever the array needs to be resized. (Note that the array should always have capacity to hold another value, for example, when it is holding 10 values the array size should be 20; the next step size up). Once it reads -10000, the program should print how many numbers it read in the format Numbers read = <n>, then exit. The program must free() the array before exiting (but after printing the how many numbers have been read). You can use scanf("%hd", &number) to read a 16 bit integer. Note: because of the way we test this, you must not call realloc() if you just read in -10000; be efficient! For example: Input 1 2 3 4 5 -10000 Result _TESTALLOC: (calloc) Add block 0, total memblks 20 _TESTALLOC: (calloc) Total number of allocations 1, total memblks 20 Numbers read = 5 _TESTALLOC: (free) Free block 0, total memblks 20 _TESTALLOC: (free) Total number of allocations 1, total memblks 0 _TESTALLOC: Total number of allocations made 1, total outstanding memblks 0
