给定字符串的字符的 ASCII 值的平均值

给定一个字符串，任务是找出字符串中字符的 ASCII 值的平均值。

例子：

Input: str =  "for"
Output: 109
'f'= 102, 'o' = 111, 'r' = 114
(102 + 111 + 114)/3 = 109 

Input: str = "geeks" 
Output: 105

方法：开始遍历字符的字符串并将它们的 ASCII 值添加到变量中。最后，将这个字符串的 ASCII 值之和除以字符的长度，即字符串中的字符总数。

C++

// C++ code to find average
// of ASCII characters
#include 
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);
    return 0;
