Determine the number of bytes necessary to store an uncompressed binary image of size 4000 × 3000 pixels
vladimir2022 [97]

Answer:  1,500,000 bytes.

Explanation:

If we assume that we have an image of 4000 pixels (picture elements) wide, by 3000 pixels height, a complete uncompressed image will be represented by 4000*3000= 12,000,000 pixels.

Now, if we are talking of a binary image, this means that each pixel will have, as a maximum, two possible values, so we will need only one bit per pixel.

This means that  we will need to store 12,000,000 bits.

As we know, 1 byte=8 bits.

So, we will need 12,000, 000/8 bytes ⇒ 1,500,000 bytes in order to store an uncompressed binary image of size 4000 x 3000 pixels.

Write a C function named apply_all that expects two arrays of integers and their sizes and dynamically allocates a new array of
andrew-mc [135]

Answer:

The function C is as follows:

int *apply_all(int arr1[], int arr2[], int size) {

  int result[size];

  for(int i =0; i<size;i++){

      result[i] = arr1[i] * arr2[i];

      printf(" %d", result[i]);

  }

  return result;

}

Explanation:

This line defines the function

int *apply_all(int arr1[], int arr2[], int size) {

This declares an array that holds the result of the function

  int result[size];

This iterates through the array

  for(int i =0; i<size;i++){

This multiplies the corresponding elements of both arrays

      result[i] = arr1[i] * arr2[i];

This prints the result of the multiplication

      printf(" %d", result[i]);

  }

This return the a pointer to the new array

  return result;

}
