Write a function that use array (y) to print the result in the figure. Then write only
the call statement to call the function.
y = -3 4 0 -1 5 -6 2 8 10 -4
Location of negative numbers:
0 --> -3
3 --> -1
5 --> -6
9 --> -4
Each function deals with null terminated C-strings. You can assume that any char array passed into the functions will contain valid, null-terminated data. Your functions must have the signatures listed below.
This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2. It should return -1 if the substring does not appear in the string.
int findSubstring(char *s, char substring[])
Q3] Create a new function with the name DrawHPyramid that takes one parameter r, which is the
number of rows. This function rather than using the ghạracter it uses + and - to draw the pyramid,
use recursion when implementing this function

- Write a function (cubeArt) to cube the first N elements in an array of doubles. The function should be passed the array and the number of elements to be cubed (the value will be replaced with its third power, e.g., if an array element is 3, it will be replaced by 27). The function should return nothing.arrow_forwardQ2: In this question, you will write a Python function to compute the Hadamard product of two matrices. The Hadamard product is the "component-wise" product of two matrices. That is, each entry of the product matrix is equal to the product of its corresponding entries of the input matrices. Here is an example: a11 a12 a21 a22 a23 a31 a13 SH a32 033 A b11 b12 b13 b21 b22 b23 b31 b32 b33. B = [an bu a21 b21 a31 b31 a12 b12 a22 b22 a32 b32 a13 b13 a23 b23 a33 b33. Hadamard product of A and B Write a Python function to compute the Hadamard product of two matrices as follows. a) The inputs to the function are two matrices. b) The function should check whether the two matrices have the same size. If not, it should print "The input matrices are not of the same size". c) If two matrices are of the same size, the function computes the Hadamard product and returns the answer. Use for loops to compute the Hadamard product.arrow_forward(Modify) Modify the program written for Exercise 9 by adding an eighth column to the array. The grade in the eighth column should be calculated by computing the average of the top three grades only.arrow_forward

It needs to work for arrays of any length. What is the minimum number of parameters your function will have?arrow_forwardComplete the function that adds 3 matrices together. The matrices will be numpy type and of the same dimension of 3 × 3. There are several ways to do this, any correct answer will be accepted. In [ ]: # add the matrices a,b,c together, these will have been passed to the function # as standard numpy matrices. Rememeber if you are unsure, just print the # elements to see how to access the matrix values. # there are several ways to do this, anyway you do this is fine import numpy as np def add_matrices(a,b,c): # initiate the matrix based on the assumption that the matrix is 3x3. matrix = np.zeros([3,3]) # your code here return matrixarrow_forward

The first parameter is an array of integers. The second parameter is an integer representing the size of the array. The third parameter takes the value to be search form.
