40: ***(Syntax)*** Write a program to calculate the number of spaces in a sentence

.length( ) function:

 sentence.length() This operator is used to calculate the number of characters in sentence .


// Write a program to calculate the number of spaces in a sentence

#include <iostream>
#include <string>
using namespace std;
int main()
{

    string sentence;
    int space = 0;

    cout << "Enter the sentence: ";
    getline(cin >> ws, sentence);

    for (int i = 0; i < sentence.length(); i++)
    {
        if (sentence[i] == ' ')
        {
            space++;
        }
    }

    cout << "There are " << space << " spaces in sentence:\n"
         << sentence;

    return 0;
}

Note:

1: Whenever you have to calculate space or some other character, Write it between ' ' not " "

2: Function of  sentence[ i ] =====> ...???...

3: Function of sentence.length() =====> ...???...

221: // In Task 2, we discussed multilevel inheritance with parameterized constructors for Student, UndergraduateStudent, and GraduateStudent classes in a university management system. Can you explain the advantages of using multilevel inheritance with specific details about the functions and data members in these classes? How were the parameterized constructors (e.g., setting student name, age, and ID) used to ensure that each class in the hierarchy correctly initializes its properties, such as creating an UndergraduateStudent named "John," aged 20, with a student ID of 12345
