C++ Exercises: Check whether a given string starts with "F" or ends with "B"

C++ Basic Algorithm: Exercise-43 with Solution

Write a C++ program to check whether a given string starts with "F" or ends with "B". If the string starts with "F" return "Fizz" and return "Buzz" if it ends with "B" If the string starts with "F" and ends with "B" return "FizzBuzz". In other cases return the original string.

Sample Solution:

C++ Code :

#include <iostream>
 
using namespace std;

string test(string str)
        {
            if ((str.substr(0, 1)=="F") && (str.substr(str.length()-1,1)=="B"))
            {
                return "FizzBuzz";
            }
            else if (str.substr(0, 1)=="F")
            {
                return "Fizz";
            }
            else if (str.substr(str.length()-1,1)=="B")
            {
                return "Buzz";
            }
            else
            {
                return str;
            }
        }
        
int main() 
 {
  cout << test("FB") << endl; 
  cout << test("Fsafs") << endl; 
  cout << test("AuzzB") << endl; 
  cout << test("founder") << endl; 
  return 0;      
}

Sample Output:

FizzBuzz 
Fizz 
Buzz 
Founder

Previous: Write a C++ program to compute the sum of the two given integers. If one of the given integer value is in the range 10..20 inclusive return 18.
Next: Write a C++ program to check if it is possible to add two integers to get the third integer from three given integers.
