原文:

给定一个句子，任务是找出句子中每个单词的 ascii 值的平均值，并与单词一起打印出来。 例:

input: sentence = "learning a string algorithm"
output: 
learning - 102
a - 97
string - 110
algorithm - 107

进场:

  1. 取一个空字符串，开始一个字母一个字母地遍历句子。
  2. 将字母添加到字符串中，并将其 ascii 值添加到总和中。
  3. 如果有空格，用总和除以字符串(单词)的长度来计算平均值
  4. 清除字符串，以便它可以用于下一个单词
  5. 也将总和设置为零。

以下是上述方法的实现:

c 

// c   program of the above approach
#include 
using namespace std;
// function to calculate the
// average of each word in a sentence
void calculateaverage(string sentence)
{
    // word initialised to an empty string
    string word = "";
    // sum of ascii values
    int sum = 0;
    int len = sentence.length();
    for (int i = 0; i < len;   i) {
        // if character is a space
        if (sentence[i] == ' ') {
            // calculate the average
            int average = sum / word.length();
            cout << word << " - "
                 << average << endl;
            // clear the word and
            // set the sum to 0
            word.clear();
            sum = 0;
        }
        else {
            // add the ascii value to sum and
            // also add the letter to the word
            sum  = sentence[i];
            word  = sentence[i];
        }
    }
    // calculate the average of last word
    int average = sum / word.length();
    cout << word << " - " << average;
}
// driver code
int main()
{
    // get the sentence
    string sentence
            = "learning a string algorithm";
    // calculate the average
    calculateaverage(sentence);
    return 0;
}
