USING ARRAYS
Q 4) Write a program to compute the following mathematical equation:
k=0nAk*B[n-k] Where n = 9
Q 5) Create a program to enter 20 elements into an array, create another array to copy only elements to the new array which are even and three digit. All other digits are to be replaced by maximum positive value.
Problem 2: Replace all vowels in sentence by the underscore character.
In this program, you ask user to enter a sentence and read it using string class function getline. Use a for loop to iterate through all characters. Please use str.at(i) method to access each string character. If a character is a vowel, replace it with ’ ’. Both upper and lower case vowels have to be replaced. Those who use an array for string are going to lose points as char.at(i) verifies that the character position in a string is valid. Example run:
Please enter a sentence:
Hello There!
You entered the sentence "Hello There!"
Your sentence after replacing vowels by underscores is H_ll_ Th_r_!
