- Write the definition of a function that takes as input two decimal numbers and returns first number to the power of the second number plus second number to the power of the first number. (4)(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.3. Using c++ Write a function that accepts an integer n and returns -1 if n is less than zero and the sum of all the integers between 0 and n (inclusive) if n is greater than or equal to zero.
- Q1: Write a C++ program to read any integer number and determine if the number is not prime using function int prime(), the answer will be printed from the main function.Q #2: Write a program in C to check a given number is even or odd.Using the function with no arguments and no return valuesQ #2: Write a program in C to check a given number is even or odd.Using the function with no arguments and one return values
- 6. 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.Problem 1 - Write a function that returns the sum of all the integer numbers dividable by 3 that are smaller than a given integer number. EXAMPLE sum3(20) 635. Write a C function that takes a positive integer n as an argument and returns 1 if n is prime, and 0 otherwise
- Q. Write a function days_in_month() that returns the number of days in a month. The function has the following prototype: int days_in_month(int month, int is_leap); Month should be an integer value between 1 and 12. The function should return (-1) if an invalid month is input. The variable ‘is_leap’ is 1 for leap years, 0 otherwise. Write program in c.Write a function to compute the nth Fibonacci number. Use your functionto solve Programming Exercise 16 from Chapter 3.C program for the longest sequence of increasing numbers. Use the function: void longestSequence(int b[], int sizeB); Input: 1 3 10 1 7 8 10 30 0 Output should be: Longest sequence is 1, 7, 8, 10, 30.
