- 4. (Prime Numbers) An integer is said to be prime if it is divisible by only 1 and itself. For example, 2, 3, 5 and 7 are prime, but 4, 6, 8 and 9 are not. Write a function called isPrime that receives an integer and determines whether the integer is prime or not. Write a test program that uses isPrime to determine and prints all the prime numbers between 1 and 1000. Display 10 numbers per line.arrow_forwardUSE C++ (Display matrix of 0s and 1s) Write a function that displays an n-by-n matrix using the following header: void printMatrix(int n) Each element is 0 or 1, which is generated randomly. Write a test program that prompts the user to enter n and displays an n-by-n matrix. Here is a sample run:arrow_forward(Q1)This is a Data Structures problem and the programming language used is Lisp. Solve the question we detailed steps and make it concise and easy to understand. Please and thank you.arrow_forward
- C++ Programming. Topic: Working with pointers and dynamic memory. Indicators. Working with dynamic memory. Dynamic arrays and their use as function parameters. Task : Describe a void function named Swap(x,y) that swaps the values stored in the variables x and (x is a real type parameter and is both input and output). Using this function , for the given variables of real type a, b, c, d, one should sequentially replace the values of the pairs (a, b), (c, d) and (b, c) and let a, b, c, d be new values .arrow_forward(IN C PLEASE) must attcah output screenshot answer properly write a function to allocate an array of 10 ints using malloc(), and see if the values are initialized to 0. You can use print_array() to check. Define 3 structs: square, rect, and circle. Then, write 3 functions area_sq(), area_rect(), and area_circ() to compute and return the area for the respective shape.arrow_forward(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward
- (C PROGRAMMING ONLY) 4. Man's Best Friendby CodeChum Admin We all know what man's best friend is. A dog! ? Let's create one in our program using the pre-existing struct Dog provided. Instructions: In the code editor, you are provided with the definition of a struct Dog. This struct needs a string value for its breed. Furthermore, you are provided with a displayDog() function which accepts a struct Dog as its parameter.Your task is to create a Dog, take in a string user input, and then set it as the Dog's breed.Finally, call the displayDog() function and pass that Dog you created.Input 1. The breed of the Dog Output Enter·the·breed·of·the·Dog:·Golden·RetrieverArf·arf!·I'm·a·Golden·Retrieverarrow_forwardC++ Coding Question, Fill the void function *n1, int *n2, int *n3) void passReference(int { // Write your code here } Rounding to nearest 10 and rotating once clockwise In this coding exercise, you are asked to write the body of a function called passReference, which takes three integers by reference, round off each number to the nearest 10, and then right rotate all the numbers clockwise only once. For example, if variables a, b, and c contains the following values: a = 214; b = 2147; c=214748; Then values of variables after calling the passReference(&a, &b, &c) will be: a = 214750 b = 210 c=2150 Sample inputs 214,2147,214748 10,20,30 0,2,3 5,9,13 2147483641,2147483635,2147483631 Sample outputs 214750,210,2150 0,10,20 0,0,0 10,0,10 2147483630,2147483640,2147483630arrow_forward(Square of Asterisks) Write a function that displays a solid square of asterisks whose side isspecified in integer parameter side. For example, if side is 4, the function displays: **** **** **** ****arrow_forward
- .“Dangling and wild pointers are known to be problems with pointers”. Justify the given statement with the helpof suitable examplearrow_forward(Rounding Numbers) Function floor may be used to round a number to a specific decimal place. The statement y = floor(x * 10 + .5) / 10; rounds x to the tenths position (the first position to the right of the decimal point). The statement y = floor(x * 100 + .5) / 100; rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines four functions to round a number x in various ways a) roundTolnteger(number) b) roundToTenths(number) c) roundToHundreths(number) d) roundToThousandths(number) For each value %3D read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hun- dredth, and the number rounded to the nearest thousandth.
