- How do I use PYTHON to create a high/low number guessing game? Assignment reads: If the user’s guess is higherthan the randomly chosen number, the program should say "Your guess was too high" and prompt theuser to guess another number. If the user’s guess was lower than the randomly chosen number, theprogram should say "Your guess was too low" and prompt the user to guess another number. Finally, ifthe user guesses correctly, the program should say the user’s guess was correct and tell the user howmany guesses it took them to get the numberarrow_forwardHow is the body of a for loop defined? A. The body of a for loop is defined by an indented block of code following the for statement, similar to the body of an if statement. B. The body of a for loop is defined by an opening curly brace, one or more lines of code and a closing curly brace. C. The body of a for loop is defined by a left parenthesis, one or more lines of code and a right parenthesis. D. For loops do not have a body. What is a for loop? A. The for loop is the new improved three loop as it was defined in Python version 2. B. The for loop enables a program to repeat a block of code multiple times. C. The for loop enables a program to repeat a block of code one time, much like the if statement. D. The for loop is a block of code included at the beginning (the for) of a program. Which of the following is an example of a sequence that might be used in a for statement? A. An integer B. A floating point number C. A list D. A boolean variable How is a...arrow_forwardC++ continued you already gave me the help from the first part. now they have added another set of instructions. original code used. Explanation Here I have created the main method. Inside the main method, I have taken input from the user for height and width and stored them into different variables. Next, I have created a loop that runs till it reaches the height of the rectangle. Inside the loop, I have created another loop that runs till the width of the rectangle. In the inner loop, I have printed the asterisk symbol. After the inner loop, I have used endl to give break and move the pointer to the new line. arrow_forward Answer C++ code: #include<iostream>using namespace std; int main(){ int height, width; // user input cin >> height >> width; // outer loop for(int i = 0; i < height; i++) { // inner loop for(int j = 0; j < width; j++) { //printing the * symbol cout << "*"; }...arrow_forward
