给定字符串字符的 ASCII 值的平均值
给定一个字符串，任务是找到字符串中字符的 ASCII 值的平均值。
示例:
Input: str = "for"
Output: 109
'f'= 102, 'o' = 111, 'r' = 114
(102 + 111 + 114)/3 = 109
Input: str = "geeks"
Output: 105

方法:开始迭代字符串的字符，并将它们的 ASCII 值添加到变量中。最后，将字符的 ASCII 值之和除以字符串长度，即字符串中的字符总数。
C++

#include <bits/stdc++.h>
using namespace std;
// Function to find average
// of ASCII value of chars
int averageValue(string s)
{
int sum_char = 0;
// loop to sum the ascii
// value of chars
for (int i = 0; i < s.length(); i++)
{
sum_char += (int)s[i];
}
// Returning average of chars
return sum_char / s.length();
}
// Driver code
int main()
{
string s = "GeeksforGeeks";
cout << averageValue(s);

Output:
101
