Hello, How can I do part 3 in c language , Part 2: Combine arrays Write a program that does the following: Creates int array array_1 of length 10. Creates int array array_2 of length 10. Takes int values from the user of for 10 values for array_1 and array_2, each. Creates a new int array array_3 which copies the values of array_1 and array_2, in interleaved order, into it. Prints out the contents of Prints out the contents of array_1, array_2 and array_3. Part 3: String / Character array Repeat Part 2, but this time use arrays of char (instead of int), and stop receiving input into array_1 and array_2 when the user hits Enter / newline and insert a Null character into the array. Here is the code that I came up with : #include <stdio.h>int main()#define MAX 10{char array_1[MAX];char array_2[MAX];printf("enter char : enter \n to stop"); printf("enter array_1 :\n");for (int i = 0; i != '\n'; i++);{scanf_s("%c", &array_1);} printf("enter array_2 :\n");for (int i = 0; i…
Describe what problem occurs in the following code. What modifications should be made to it to eliminate the problem? int[] sums = {6, 12, 3, 32, 12, 10, 9, 6}; for (int index = 1; index <= sums.length; index += 1) { System.out.println(sums[index]); }
Write down declarations for variables of the following type (you get to choose the name): a) An integer. b) Asingle-precisionfloatingpointnumber. c) An array of 10 double-precision floating point numbers. d) A pointer to a double-precision floating point number. e) An array of 10 pointers to characters (C strings). f) A 2d array of 8x8 doubles.
Look at the following C++ code and comment each line about how it works with pointer. int i = 33; double d = 12.88; int * iPtr = &i; double * dPtr = &d; // iPtr = &d; // dPtr = &i; // iPtr = i; // int j = 99; iPtr = &j; //
CODE IN JAVA design a program that grades arithmetic quizzes as follows: (Use the below startup code for Quizzes.java and provide code as indicated by the comments) 1. Ask the user how many questions are in the quiz. 2. Use a for loop to load the array. Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34, 7, 13, 100, 8 might be the key for a 5-question quiz. You will need to store the key in an array called "key". 3. Ask the user to enter the student's answers for the quiz to be graded. There needs to be one answer for each question. Note that each answer can simply be compared to the key as it is entered. If the answer is correct, add 1 to a correct answer counter. need this in a separate for loop from the loop used to load the array. 4. When the user has entered all of the answers to be graded, print the number correct…
(C PROGRAMMING ONLY) 1. Spell-it-out!by CodeChum Admin Are you intimidated with complicated words? Don't be! The trick is to break it down letter by letter! Let’s create a program that prints out the character in the array index indicated by the input integer. For example, if the array has 3 character elements, 'j', 'r', and 'd', and the inputted integer value is 1, then we print 'r' because 'r' is found at index 1. Instructions: In the code editor, you are provided with an array of characters (or a string).Your task is to ask the user for an integer input which represents the index and then print out the character of the string found at that index.Input 1. Index of the array Output Enter the index: 4r
Given the Array declaration below, determine the output: int T[8] = {2, 3, 7, 9, -1, 2, 4, 5}; int x = 5; cout << T[x-2] / T[12-2*x]; int y = -3; cout << pow(T[y+4],T[3-y]);
please do this program in java in details. You have been given two random integer arrays as arr1 and arr2 of size n and m respectively. Boththe arrays contain numbers from 0 to 9 (i.e. single digit integer is present at every index). The ideahere is to represent each array as an integer in itself of digits n and m.You need to find the sum of both the input arrays treating them as two integers and put the result inanother array i.e. output array will also contain only single digit at every index.Input Format:Line 1: Size of first arrayLine 2: Elements of first arrayLine 3: Size of second arrayLine 4: Elements of second arrayOutput Format:The resultant arraySample Input 1:36 2 437 5 6Sample Output 1:1 3 8 0Sample Input 2:49 7 6 134 5 9Sample Output 2:1 0 2 2 0
Write a program named as reverse.c that reads a message, then prints the reversal of the message. The output of the program should look like this: Enter a message: Don ’t get mad, get even. Reversal is : .neve teg ,dam teg t ’noD Hint: Read the message one character at a time (using getchar) and store the characters in an array. Stop Reading when the array is full or the character read is ‘\n’. The framework of reverse.c is as below: /* reverse.c */ #include #define N 50 int main(){ int arr[N],i=0; char ch; printf("Enter a message: "); /* Put code here to get input from user by using getchar() */ printf("Reversal is: "); /* Put code here to print out the reversal by using putchar()*/ printf("\n"); return 0; }
3. Write a program in C++ to store all the numbers between n and m into an array using a loop. (Note: n <= m). 4. Write a program in C++ to store all odd numbers between n and m into an array using a loop. (Note: n can be greater, equal or less than m and |n-m|<=100). 5. Write a program that accepts two arrays of integers and print true if the first array is equal to the second array, otherwise print false. 6. Write a program in C++ that constructs a two-dimensional array of integers with 6 rows and 8 columns. Fill the array with a multiplication table, so that array element [i][j] contains the value i * j. Then print the array as a table.
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.
