Write a darken_filter and change_picture function that modifies the pixels in the left half of the image to be darker. You can darken a pixel by subtracting the same value from each of the red, green, and blue values of the pixel.

for every pixel in the left half of the image
set pixel red to be (red - DARKENING_FACTOR)
set pixel green to be (green - DARKENING_FACTOR)
set pixel blue to be (blue - DARKENING_FACTOR)

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.

Assume a class window with accessor method getwidth that accepts no parameters and returns an integer. assume further an array of 3 window elements named winarr, has been declared and initialized. write a sequence of statements that prints out the width of the widest window in the array.

Write a program that reads a set of floating-point values. ask the user to enter the values, then print • the average of the values. • the smallest of the values. • the largest of the values. • the range, that is the difference between the smallest and largest. of course, you may only prompt for the values once.
