Consider the producer-consumer problem where the producer produces items to be consumed by the consumer. A solution of the problem is to be implemented using threads. The main process will run producer and consumer as two different threads. The producer will put the items it generates into a buffer of length 15. The consumer reads the elements of the buffer to get the items. A solution is given below. Each item produced and consumed are also printed to the screen. Run the program several times and find a sample run when the items produced are not correctly consumed. Explain why the program does not always work correctly.
In C++ Create an array of head pointers, statically allocated of size 101 of that type: Now, create a pointer that can point to the first element: Show how to dynamically allocate an array of 101 elements of head pointers: Write the code to initialize each element to NULL: Rewrite the code to initialize each element to NULL using pointer arithmetic:
int main(int argc, char **argv) { float *rainfall; float rain_today; // rainfall has been dynamically allocated space for a floating point number. // Both rainfall and rain today have been initialized in hidden code. // Assign the amount in rain_today to the space rainfall points to. return 0; }
JAVA CODE PLEASE Recursive Functions Quiz by CodeChum Admin Create a recursive function named sequence that accepts an integer n. This function prints the first n numbers of the Fibonacci Sequence separated by a space in one line Fibonacci Sequence is a series of numbers in which each number is the sum of the two preceding numbers. In the main function, write a program that accepts an integer input. Call the sequence function by passing the inputted integer. Input 1. One line containing an integer Output Enter·a·number:·5 0·1·1·2·3

c++ programming Write a function named maxCols which stores the maximum value in each row of a 3x3 2D array into a 1D array. This function should accept a 3x3 2D array, a 1D array and the size of each dimension as parameters. Example Calling maxCols with this 2D array:3 7 2 9 3 6 8 5 6 Results in the 1D array storing the values 7,9,8.
