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; }
Consider the following C++ function. int mystery(int num1, int num2){if (num1 > 0){for (int i = 1; i <= num1; i++)num2 = num2 * i;return num2;}else if (num2 > 0){for (int i = 0; i <= num2; i++)num1 = num1 + i;return num1;}return 0;}What is the output of the following statements?a. cout << mystery(4, -5) << endl;b. cout << mystery(-8, 9) << endl;c. cout << mystery(2, 3) << endl;d. cout << mystery(-2, -4) << endl;

In C, Assume that the int variables i and j have been declared, and that n has been declared and initialized.Write code that causes a "triangle" of asterisks of size n to be output to the screen. Specifically, n lines should be printed out, the first consisting of a single asterisk, the second consisting of two asterisks, the third consisting of three, etc. The last line should consist of n asterisks. Thus, for example, if n has value 3, the output of your code should be******You should not output any space characters.
THIS IS IN JAVA A programmer intended to compute (a AND b) OR c, and wrote the following code, which sometimes yields incorrect output. Why? <pre><code>c | (a & b)</code></pre> A. The parentheses are interfering, and should not be present B. The ORing with c should appear after the parentheses, not before C. The bitwise operators should be replaced by logical operators D. If code only sometimes yields incorrect output, the compiler is likely broken
Write a “C” program to find the summation of the following series: 1/8+ 1/27 + 1/64 + 1/125 + 1/216 + .............. + 1/(n+1)3Hint: To compute the power of a number, you can apply basic mathematics multiplications equations or use the pow() function computes the power of a number.The basic mathematics multiplications equations:For example: [In Mathematics] x4 = x*x*x*x [In programming]The pow() function:The pow() function takes two arguments (base value and power value) and, returns the power raised to the base number.For example, [In Mathematics] xy = pow(x, y) [In programming]The pow() function is defined in <math.h> header file (#include<math.h>)
Use the following skeleton code to write a C program (NOT C++) which filters out words from input which can be typed entirely with either the left hand (QAZWSXEDCRFVTGB) or right hand (YHNUJMIKOLP) #include "general.h" int main(void){int pipe1[2];/*pipe for child 1 and 2 to share*/int pipe2[2];/*pipe for child 2 and 3 to share*/int status; /*setup pipe 1*//*Fork and call child 1 process. /*parent closes pipe ends it no longer needs*/ /*set 2nd pipe*/ /*Fork and call child 2 process. Don't forget to close any fds you will not want open in the childbefore you call the child routine */ /*parent closes pipe ends it no longer needs*/ /*Fork and call child 3 process.*/ /*parent closes. rest of pipe ends*/ /*wait for all 3 children*/ return(0);}
1.The following is the C code that you need to implement for this lab: uint8_ t f(uint8_tn) return(n<2)?(n):(f(n-1)+f(n-2)); The main function can be assumed as follows: int main() uint8_ t x; x=f(???); return 0; Obviously, " ? ? ? " is representing a value used to test the algorithm! Is "f"recursive? a.No answer text provided. b.Yes c.no d.depends on whether it is in for main 2.First, make the code in the previous question an actual C program so that it can be compiled and it runs. Play with it so that you feel comfortable with the logic of the code. Then implement the code in TTPASM. Note that you need to preserve the actual C code structure, this means you cannot it into a non-recursive subroutine. Furthermoreall conventions discussed in class regarding subroutines must be followed. The idea is that I should be able to substitute f with my own code, and main should work. Or, I can substitute main with my own, and f should work. Attach the source code of your assembly…
Write a c program dist.c that calculates the distance between two points and prints the result on the screen. The cartesian coordinates of the points would be given in the command line as 6 parameters. Your program should check if the number of arguments provided is correct and that the six coordinates are valid numbers of typedouble.dist.exe x1 y1 z1 x2 y2 z2For example, to calculate the distance between the two points (0, 0, 0) and (1, 1, 1), the program would be run as:dist.exe0 0 0 1 1 1and the screen output would be1.7320
Consider the following program in C-like syntax:void f1();void f2();int main(){int x, y;...}int f1()int a, b, x;...}int f2(){int b, c, x, y;...} If the programming language uses dynamic scoping, what are the variables that arevisible in the last function in the following call sequences? Give not only the names ofthe variables, but also where they are declared.(a) main → f1 → f2(b) main → f2 → f1
Write a C++ program: to iteratively compute Fibonacci numbers (named after an Italian mathematician). Some Fibonacci numbers are 1,1,2,3,5,8,... where the next number is found by summing the preceding two numbers. Your program is not assured of recieving good data, thus if -2 is recieved as the number of numbers, then an error should be reported. Try n = 5, 7, 10, -3
I need the code in C programing i am begging you please. There are several test cases. Each test case begins with a line containing a single integer n (1≤n≤1000). Each of the next n lines is either a type-1 command, or an integer 2 followed by an integer x. This means that executing the type-2 command returned the element x. The value of x is always a positive integer not larger than 100. Given a sequence of operations with return values, you’re going to guess the data structure. It is a stack (Last-In, First-Out), a queue (First-In, First-Out), a priority-queue (Always take out larger elements first), not sure(It can be more than one of the three data structures mentioned above) or impossible(It can’t be a stack, a queue or a priority queue). Sample Input Sample output 6 1 1 1 2 1 3 2 1 2 2 2 3 6 1 1 1 2 1 3 2 3 2 2 2 1 2 1 1 2 2 4 1 2 1 1 2 1 2 2 7 1 2 1 5 1 1 1 3 2 5 1 4 2 4 1 2 1 queue not sure impossible stack priority queue impossible
