Write a function call to ConvertVolume() to store the number of quarts, pints, and ounces within the integer variables numQuarts, numPints, and numOunces, respectively. Ex: If the input is 157, then the output is: Quarts: 4 Pints: 1 Ounces: 13 1 #include 3 void ConvertVolume (int totalOunces, int* numQuarts, int* numPints, int* numOunces) { totalOunces / 32; N3589 2 4 *numQuarts 6 7 totalOunces = totalOunces % 32; 10 11} 12 13 int main (void) { 16 17 *numPints = totalOunces / 16; totalOunces = totalOunces % 16; *numOunces = INN totalOunces; 14 int totalOunces; 15 int numQuarts; int numPints; int numOunces; 18 19 20 21 22 23 printf("Quarts: %d\n", numQuarts); 24 printf("Pints: %d\n", numPints); 25 printf("Ounces : %d\n", numOunces); 26 27 return 0; 28 } scanf("%d", &totalOunces); /* Your code goes here */
Please answer it in Python 1) Write a function start_by taking a letter and a word as an argument and returning True if the word begins with the letter given as an argument, False otherwise. Example: start_by('h', 'hello') is True but start_by('e', 'wheel') is False. 2) Write a function Contains_vowel that takes a word as an argument and returns True if the word contains at least one vowel, False otherwise.
Write a function flipCase that accepts a word as an argument and returns the same word but with each upper case letter switched to lower case and vice-versa. Example: >>> flipCase('ostrich')'OSTRICH' #note the lanuage is in python
Consider the function definition below. Assume x = 5, y = 3 and j = 8 as the function starts. Which variables will change after the function finishes? void findout (int &x, int y, int &j) { for (int i = 1; i 5) { x = 2*x - 3*y; y = 4 + 3 x; } else { Oi y = 2*x - 3; x = 4 + 3% y; } } // end of for loop x and y y All three since the first and last are references. x and j
Study the following function calls and then write the complete function to calculate and return the answer in an algorithm.2.1.1 display determineAngle (degrees)The function must determine and return the results if an angle is equal to 90degrees, display the message “The angle is a right angle”; else display the message “The angle is not a right angle”.2.1.2 If getResults(summative1, summative2) = trueThe function must determine and return results to indicate if the student has passed or not. The student will pass the module if the final mark of one of the summative test mark is 50 and above.
4. You are given the following functions: int functionA(int a) { printf ("a-sd\n", a); if (a==1) return 1; else return functionB (a-1) *2; int functionB (int b) { printf ("b=3d\n",b); if (b--1) return 1; else return functionA (b-1) *3; Write the main function. Your main function should prompt the user for input and then call the mutual recursion by passing in the user's input. The guidelines are described below. int main () { //declare int a to receive user input and int result to receive result of mutual recursion //using a while loop, prompt user for input. The number entered //must be bigger than 1, otherwise repeat user input with an error //message. //call functionA () with int a as input argument. Receive the result in int result. //print result return 0;
Which of the following is a correct and complete function definition? a. double funct(double x) { return 2*x; } b. double funct(Int x) { return (x-3); } c. int funct (x) { return (++x); } d. int funct (int x); e. void funct(x=7) { return 8; } f. void funct(int x=7) { return x/3; }

6. You are given the following function that will calculate the sum of the first n numbers where n is an argument to the function. When n is 10, it should print out 55, but instead it prints out 10. Find and fix the problem. int findsum (int n) { int sum = 0; for (int i=1; i
Complete the following TODO by defining a function called add_func(). Define a function called add_func() that takes two arguments. The function should adds the two arguments together using + and return the output. For example, if the input values for the arguments are 1 and 2, then 3 should be returned. Likewise, if the input arguments are "good" and " day", then "good day" should be returned. # TODO print(f"add_func output for 1 + 2: {add_func(1, 2)}") print(f"add_func output for good + day: {add_func('good',' day')}") todo_check([ (add_func(1,2) == 3,'add_func() did not return 3 when using input values 1 and 2.'), (add_func('good',' day') == "good day",'add_func() did not return "good day" when using input values "good" and " day"') ])
Write a function definition for a function named getLast that does the following 1) Accepts an string as an input parameter 2) Returns the last character in the string. Example Given the string "Helle" this function returns o.
Problem 2: Write a function called digitMatch. The function has three integer parameters first , second and third that are positive and have the same number of digits. It returns the number of positions where their digits match. For example, if the function was applied to 17345, 97813 and 17313 it would return 1 because only the 2nd digits match. If parameters have illegal values your function can operate however you choose. For example, a program that uses the function follows. int main() { cout <« digitMatch(168, 567, 767) « endl; // prints 1 cout <« digitMatch(143, 243, 343) « endl; // prints 2 return 0; }
