In C89 programming:
(a) What is the difference between a pointer to an array of ints (“x”) and a pointer to the first element of the same array (“y”)?
(b) What is the only character that cannot appear in a string, and why?
Homework Answers
a) There is a difference at run-time.
int[]is an array of primitive int values.Integer[]is an "object" array, holding references to Integer objects.- Most important practical difference:
int[]cannot holdnullvalues.
b) The escape character ( \e , ASCII 0x1b) isn't part of the source character set and even may not exist at all (on a non-ASCII system), and cannot appear in a string.

- Write a program that performs several operations on an array of positive ints. The program should prompt the user for the size of the array (validate the size) and dynamically allocate it. Allow the user to enter the values, do not accept negative values in the array. - Your program should then define the functions described below, call them in order, and display the results of each operation: a) reverse: This function accepts a pointer to an int array...

Write a function that gets a 2-d array of given dimensions of ints. It returns true if the array contains two rows with exactly the same values in the same order, and returns false otherwise, bool contains_equal_rows(int height, int width, const int ar[height] [width]) Examples: On input {{1,2,3,4}, {2,3,4,1}, {1,2,3,4}} it returns true. On input {{1,2,3,4}, {2,3,4,5}, {3,4,5,6}} it returns false. On input {{1,1,1,1}, {2,2,2,2}, {1,1,1,6}} it returns false.

Given an array length 1 or more of ints, return the difference between the largest and smallest values in the array. Examples: largeDiff (410, 3, 5, 6}, 4) - 7 largeDiff ({7, 2, 10, 9}, 4) - 8 largeDiff ({2, 10, 7, 2}, 4) + 8 largeDiff ({2}, 1) = 0 code.cpp + New I Full Screen 2- int largeDiff (const int a[], int n) { 3 4 5}

C programming 1) When setting a two-dimensional character array, how is the size (number of characters) in the second dimension set? Select an answer: The number of elements are equal to the average size of all the strings. To the length of the longest string; you don't need to add one because the first array element is zero. To the length of the longest string, plus one for the null character. The second dimension is equal to the number of...

i have a question need it to get solved in 20 minutes please in C++ programming . this is the question: Write a function GetPtrMaxElem that takes as input the base address of an array of ints and the number of elements. The function should inspect the contents of the array and return a pointer to the last array element with the maximum value. (Hint: what should the return type be?)

Write a program in LEGv8 assembly to copy a null-terminated ASCII string from array y to array x; converting every 'a' character in the source string to 'b' in the destination string. In other words, for each character in array y: else Assume that the base address of the arrays x and y are in registers X0 and X1, respectively. The ASCII code for characters 'a' and 'b' is 113 and 114 respectively [25 pts]. * Null-terminated means that a...

Consider a non-empty int array ints. A contiguous subarray ints[ start .. start + len -1 ] (with starting index start and length len) is called a flat if all elements of that subarray are equal. Furthermore, such a subarray is called a plateau if it is flat and each of the elements ints[start -1] and ints[start + len] that immediately proceed/succeed the subarray are either nonexistent (i.e., out of array’s index range) or are strictly smaller than the elements...
