Python only* Use recursive function*. Define concentricCircles with 4 parameters Use def to define concentricCircles with 4 parameters here is the specification for concentricCircles function: It draws a series of concentric circles, where the first parameter specifies the radius of the outermost circle, and the second parameter specifies the number of circles to draw. When viewed as nested rings, all rings should have the same thickness. The third and fourth parameters specify an outer color and an other color, respectively. The outer color is used for the outermost circle, and then every other circle in to the center alternates between that color and the other color. We will test both how many circles are drawn as well as whether the correct circles are drawn in the correct order. Hint: Each function call frame only needs to draw a single circle. Note that you must use the turtleBeads drawDot function to draw each circle Do not use any kind of loop Within the definition of…

9-Given the code segment below, what should be the data type of the formal parameter in the function prototype of func(), given the call from main()? Note that function prototypes need not include the identifier (name of the parameter), so do NOT put any variable name in your answer. Remove any space in your answer. If the accessing is wrong, answer INVALID (in all capital letters). void func( ______ ); int main() { double aData[6][4]; func(&aData[4]); return 0; }
Briefly (1-2 lines) explain the purpose of the function foo.
AIM: TO SWAP 2 NUMBERS WITHOUT USE OF TEMPORARY VARIABLE THEORY: C is a general-purpose, middle level, procedural computer programming language supporting structured programming, lexical variable scope, and recursion, with a static type system. C is an imperative procedural language. Let a and b be variables in which integral values are being inserted . tw numbers can be swapped without using a temporary variable by using arithmetic operations. Another alternative method is by use of logical operators. ALGORITHM: STEP 1: Start STEP 2:Print "Enter two numbers'" STEP 3: Input x,y STEP 4:Print “ Numbers x,y before swapping STEP 5: x x+y STEP 6: y<– x-y STEP 7: x x-y STEP 8: Print “ Numbers x,y after swapping " STEP 9: Stop
Example 1: Define a function that takes an argument. Call the function. Identify what code is the argument and what code is the parameter.Example 2: Call your function from Example 1 three times with different kinds of arguments: a value, a variable, and an expression. Identify which kind of argument is which. Example 3: Construct a function with a local variable. Show what happens when you try to use that variable outside the function. Explain the results.Example 4: Construct a function that takes an argument. Give the function parameter a unique name. Show what happens when you try to use that parameter name outside the function. Explain the results.Example 5: Show what happens when a variable defined outside a function has the same name as a local variable inside a function. Explain what happens to the value of each variable as the program runs.The code and its output must be explained technically whenever asked. The explanation can be provided before or after the code, or in the…

Write a value-returning function, isVowel, that returns the value true if a given character is a vowel and otherwise returns false. What is the data type of the value-returning function isVowel? What are the formal parameters to the function? What are the data types on the formal parameters? What passing technique is used on those parameters? Write the definition for the isVowel function in the space below.
Explanation: pi(x) is a function that has nothing to do with pi (why? because MATH, that's why) but rather is a function meaning "The number of prime numbers <= x". So pi(7) = 4, since there are four prime numbers <= 7, namely: 2, 3, 5, and 7. (1 is not a prime number!) The big sigma is the summation symbol. It means add up the results for pi(x) from x = i to x = j. So if we sum up all pi(x) from x = 7 to 11, we are computing: pi(7) + pi(8) + pi(9) + pi(10) + pi(11) Now pi(7) through pi(10) are all the same, right? Since the next prime number is 11. So all of those are 4. And then pi(11) is 5, since there's now five prime numbers <= 11: 2, 3, 5, 7, 11. So the answer is: 4 + 4 + 4 + 4 + 5 = 21. (Your code will output: "The answer is: 21"). Can you explain and write it code help me please? C++
