C++ Exercises: Count the string 'aa' in a given string and assume 'aaa' contains two 'aa'

C++ Basic Algorithm: Exercise-26 with Solution

Write a C++ program to count the string "aa" in a given string and assume "aaa" contains two "aa".

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;


int test(string s)
        {
            int ctr_aa = 0;
            for (int i = 0; i < s.length() - 1; i++)
            {
                if (s.substr(i, 2) == "aa")
                {
                    ctr_aa++;
                }
            }
            return ctr_aa;
        }
        
int main() 
 {
  cout << test("bbaaccaag") << endl;  
  cout << test("jjkiaaasew") << endl;  
  cout << test("JSaaakoiaa") << endl;  
  return 0;    
}

Sample Output:

Previous: Write a C++ program to create a new string which is n (non-negative integer) copies of the the first 3 characters of a given string. If the length of the given string is less than 3 then return n copies of the string.
Next: Write a C++ program to check if the first appearance of "a" in a given string is immediately followed by another "a".
