Step by step
Solved in 3 steps with 1 images
- The language we are using here is in Racket. Please enter the following code: (cond ((equal? 16 3) (+ 3 8)) ((equal? 16 8) 12) (else (* 6 3))) Write the return value for the above code. If replacing all of the 16's in the above code with 8, what is the return value? What about replacing the 16’s with 3? What does the cond function do?Write a C99 function that includes the following sequence of statements:x = 21;int x;x = 42;Run the program and explain the results. Rewrite the same code in C++and Java and compare the results..Write a function: int calculate(int x); In c++, the function returns value of 2%x + 3.
- Write a function that displays all the numbers between two integers in n lines, that are divisible by 5 or 7 (not by both). So, the function should take as parameters the minimum and maximum of integer numbers and n. If no values are passed to them, this function should display the numbers between 1 and 100 in 10 lines. Write a test program to test your function. *Output of the numbers should be formatted well in C++5. Write a C function that takes a positive integer n as an argument and returns 1 if n is prime, and 0 otherwiseIn C++: Examine the code segment. What will be printed? If there are any errors indicate the nature of each error. int a[7] = {31, 12, 32, 14, 25, 16, 27}; int *ptr; ptr = & a[2]; for ( i=1; i<=5; i=i+2) cout << *(ptr +i); cout << a[0] << *ptr << *ptr - 2 << *(ptr -1)) << endl;
- Write a simple C++ code as I am a beginner. The picture of the question is given below. Create separate functions.Write output of the following c++ code by completing it with explanation of all iterations Need explanation of code line by line how it will execute. Code #include <iostream> Using namespace std; int fun1(int); int fun(float); int fun1(int n){ if(n<=1) return 1; else return n*fun(n-1); } int fun(float n){ if(n<=1) return 1; else return n*fun(n-1); } int main(){ int n=5; cout<<fun1(n); cout<<fun(4.3); return 0; }What is wrong with the following C++ function? void Maximum(int a, int b, int& max) { if (a > b) max = a; else max = b; return max; }
- Write a C++ function with the following header to format the integer with the specified width. Void format(int number, int width, char [] res) The function returns a string (res) for the number with one or more prefix 0s. The size of the string is the width. For example, format(34, 4, res) returns res as 0034 and format(34, 5, res) returns res as 00034. If the number is longer than the width, the function returns the string representation for the number. For example, format(34,1, res) returns res as 34. Write a test program that prompts the user to enter a number and its width and displays a string returned by invoking format (number, width, res). Note: res is the array of characters that supposed to return your result from the functionIn C++, Given the following function prototype: void testDefault(int a, int b = 7, char z = '*'); Indicate if each of the following function calls are valid or invalid a) testDefault(5); b) testDefault(); c) testDefault(6, '#'); d) testDefault(0, 0, '?');PLEASE SOLVE THIS IN C++ CODE ONLY! PLEASE READ AND DO THE PROGRAM WITH ACCORDING TO THE CONDITIONS GIVEN. PLEASE ALSO WRITE THE USE OR FUNCTIONS OF EACH CODE USED BY INSERTING ITS USE EVERY LINE USING "//" A palindrome is a string that reads the same from front to back as it does from back to front, e.g., "racecar", "radar", "21012". Write a program that will identify whether a given line of input is a palindrome or not. Your program must also be able to determine the following sample inputs as palindromes, aside from identifying one-word inputs: Able was I 'ere I saw Elba. Madam, I'm Adam. A man, a plan, a canal, Panama. These samples require that your program must ignore spaces and punctuations, and consider uppercase and lowercase letters to be the same. Include necessary functions in your program to process the input. You can also use existing functions from the string library.
