Here we will see how to get the average of n odd natural numbers. The n is given by the user. To get the ith odd number we can use this formula 2*i+1. Here also we are using this formula. Let us see the algorithm to get the clear idea.
Algorithm
avgOddNaturalNumber(n)
Begin sum := 0 for i in range 0 to n-1, do sum := sum + (2i + 1) done return sum/n End
Example
#include<iostream> using namespace std; float asciiAverage(string str){ int sum = 0; for(int i = 0; i<str.size(); i++){ sum += int(str[i]); } return sum/str.size(); } main() { string str; cout << "Enter a string: "; cin >> str; cout << "ASCII average is: " << asciiAverage(str); }
Output
Enter a string: Hello ASCII average is: 100
