给定一个驼峰命名的字符串，将其转换为句子格式

//including the required libraries
#include <bits/stdc++.h>
using namespace std;

//convert camelcase string to sentence case respectively
void sentenceCase(string str){

   //getting the length of string
   int len = str.length();

   //iterating over the string
   for(int i=0;i<len;i++) {

      //printing the first character of the string
      if(i==0){
         cout << str[0];
      } else {

         //check if current character is in upper case convert to lower case and insert a space before it to separate the words
         if (str[i] >= 'A' && str[i] <= 'Z'){

            //printing a space before character
            cout << " " ;
            char ch = (char)tolower(str[i]);

            //printing the character in lower case
            cout << ch;
         }

         //if character already in lower case print as it is
         else
            cout << str[i];
      }
   }
}
//calling the method
int main(){

   //sample string
   string s = "ConvertCamelCaseToSentenceCase";
   cout<<"Entered String :"<<s;
   cout<<"\nConverted String:";

   //print the sentence case
   sentenceCase(s);
   return 0;
}

Entered String :ConvertCamelCaseToSentenceCase
Converted String:Convert camel case to sentence case
