write program that lets the user enter a sting and displays te character that appears most frequently in the string. A space can be the most frequent in the string, but do not include it for the count.

Write program that uses a do or a while loop that has the user enter golf scores, terminated by a zero. After the zero has been entered, display the number of scores entered and their average.

Write program that lets the user enter a string and displays the letter that appears most frequently in the string, ignore spaces, punctuation, and Upper vs Lower case.

Create program that will calculate the factorial of any user entered integer.

Write program to print all natural numbers in reverse (from n to 1). - using loop

Create program to implement BINARY SEARCH ALGORITHM. Ask the user to enter 10 different values Sort the elements using any sorting algorithm in void sort () function
