Consider a two-by-three integer array t.
h) Write a series of statements that initializes each element of t to zero. Do not use a repetition statement.
i) Write a nested for statement that initializes each element of t to zero.
j) Write a nested for statement that inputs the values for the elements of t from the user.
k) Write a series of statements that determines and displays the smallest value in t.
l) Write a printf statement that displays the elements of the first row of t. Do not use repetition.
m) Write a statement that totals the elements of the third column of t. Do not use repetition.
n) Write a series of statements that displays the contents of t in tabular format. List the column indices as headings across the top, and list the row indices at the left of each row.
Consider the following code:
int a[5] = {1,3,5,7,9};int b = a[3]; // <--- here
Rewrite the last statement (marked “here”) without using array brackets [ ].
Group of answer choices
int b = a + 3;
int b = *(a + 3);
int b = *a + 3;
int b = *(a + 2);
You’re given an array of integers and another array of three distinct integers. The first array is guaranteed to only contain integers that are in the second array, and the second array represents a desired order for the integers in the first array. For example, a second array of [x, y, z] represents a desired order of [x, x,…,x, y, y,…,y, z, z,…,z] in the first array. Write a program that sorts the first array according to the desired order in the second array. The program should perform this in place (i.e.., it should mutate the input array), and it shouldn’t use any auxiliary space. Note that the desired order won’t necessarily be ascending or descending and that the first array won’t necessarily contain all three integers found in the second array-it might only contain one or two. Please Don't Use Chat GPT Answers
Sample input
array = [1,0,0,-1,-1,0,1,1]
order = [0,1,-1]
Sample output [0,0,0,1,1,1-1,-1]
