- Use C++ Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. Ex: If the input is: n Monday the output is: 1 Ex: If the input is: z Today is Monday the output is: 0 Ex: If the input is: n It's a sunny day the output is: 2 Case matters. n is different than N. Ex: If the input is: n Nobody the output is: 0 Your program must define and call the following function that returns the number of times the input character appears in the input string. int CountCharacters(char userChar, string userString)3.Create a C++ function to take input an integer parameter n and return whether the number is a power of 2 or not. bool checkPowerof2(int n) { // Return true if n is power of 2 }Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of the value Step 2: Repeat Step 1 until we get a single-digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise not Here is the sample output:
- (Practice) For the following function headers, determine the number, type, and order (sequence) of values that should be passed to the function when it’s called and the data type of the value the function returns: a. int factorial(int n) b. double volts(int res, double induct, double cap) c. double power(int type, double induct, double cap) d. char flag(char type, float current, float time) e. int total(float amount, float rate) f. float roi(int a, int b, char c, char d, float e, float f) g. void getVal(int item, int iter, char decflag, char delim)Use c++ Write a program whose inputs are three integers, and whose outputs are the largest of the three values and the smallest of the three values. Ex: If the input is: 7 15 3 the output is: largest: 15 smallest: 3 Your program must define and call the following two functions. The LargestNumber function should return the largest number of the three input values. The SmallestNumber function should return the smallest number of the three input values.int LargestNumber(int num1, int num2, int num3)int SmallestNumber(int num1, int num2, int num3)Write a function that receives 5 integers and returns the sum, average and standard deviation of these numbers. Call this function from main() and print the results in main(). Y c program h....
- 5. Write a C function that takes a positive integer n as an argument and returns 1 if n is prime, and 0 otherwise6. use c ++ to Write a function sumDigits, that accepts a positive integer n and returns the sum of the digits in that integer; thus, sumDigits(34) would return 7 (e.g., 3+4). Use the techniques from the roman numeral problem to extract the digits.C++ Write a function that takes as input a positive integer n and returns the n-th harmonic number.Reminder: the n-th harmonic number is equal to 1+(1/2)+(1/3)+(1/4)+...+(1/n)
- 5.19 In Python Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_value)) Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles.Study the block of codes below: int main() { char c[2] = "A";} What would the output be if the following code is added at the end of the main() function? printf("%c", c[0]);Question 1 This question deals with multiplying a 2 X 3 matrix by a 3 X 2 matrix. Your job is to input matrix A, followed by matrix B, then produce matrix C which is the product of A and B. At run time, please use the following for matrix A 1 2 3 4 5 6 followed by the following data for matrix B: 6 5 4 3 2 1 Your program should input the values for A and B in function main, then call a function matrix_mult to produce matrix C which consists of the product of A and B. Please use the following for naming your variables: Ar1c1, Ar1c2, Ar1c3. ..., where Ar1c1 refers to row 1, column 1 of matrix A, etc. (There will be a lot of variables). Do not use arrays to solve this problem.
