Answer 1

#include <bits/stdc++.h>

using namespace std;

void printInitials(const string& name)

{

    if (name.length() == 0)

        return;

    // Since touuper() returns int, we do typecasting

    cout << (char)toupper(name[0]);

  

    // Traverse rest of the string and print the

    // characters after spaces.

    for (int i = 1; i < name.length() - 1; i++)

        if (name[i] == ' ')

            cout << " " << (char)toupper(name[i + 1]);

}

  

// Driver code

int main()

{

    string name = "prabhat kumar singh";

    printInitials(name);

    return 0;

}

Output will be of format:
