Write a C function named apply_all that expects two arrays of integers and their sizes and dynamically allocates a new array of

integers whose size is the product of the 2 array sizes. The function should loop through the second array and multiplies each element across each element of array 1 and store the product in the newly created array. The function should return a pointer to the newly allocated array.

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;

}

A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter
trapecia [35]

Answer:

5 Letters

Explanation:

So we need 12 distinct codes made of a single letter or a pair of letters.

What would be the least number of letters?

Lets try with 3 letters A, B and C

The possible combinations are: A, B, C, AB, AC, BC

These are 6 codes and we need 12 so lets try more A, B, C and D

The possible combinations are: A, B, C, D, AB, AC, AD, BC, BD, CD

These are 10 codes and we need 12 so lets try more A, B, C, D and E

The possible combinations are:

A, B, C, D, E, AB, AC, AD, AE, BC, BD, BE, CD, CE, DE

Finally we got 15 distinct codes which are more than 12 so the least number of letters needed are 5.

Using formula:

Four letters = 4C1 + 4C2 = 4 + 6 = 10

Five letters = 5C1 + 5C2 = 5 + 10 = 15
