Write a program that calculates the area (a) of a triangle given two values b (base) and h (height) and using the formula area = (base * height) / 2 .The program should include a function called calculate_area which has two input parameters(b and h) and one output parameter (a).The user is prompted to enter two input values that will be used as base (b) and height (h) thenthe function calculate_area uses those two values as input parameters returns the calculatedarea (a) as an output parameter. After using the function calculate_area the program shoulddisplay the calculated area (a).Hint: use a pointer for the output paramete
COM. In C programming.........Write a function which returns most occuring digit in a number.If there is no repeating digit...it should print the maximum digit in that number. If the input is 1226, the output should be 2 If the input is 1234, the output should be 4 If the input is 33477888, the output should be 8 Function prototype: int mostOcurringDigit(int n); The main method is written under int main() { int n; scanf("%d", &n); printf("Most occuring digit from %d is %d", n, mostOccuringDigit(n)); }
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;
