C++ String Exercises: Check if two characters present equally in a string

C++ String: Exercise-9 with Solution

Write a C++ program to check whether two characters appear equally in a given string.

Visual Presentation:

Sample Solution:

C++ Code :

#include <iostream> // Including input/output stream library
#include <string> // Including string handling library

using namespace std; // Using the standard namespace

// Function to count occurrences of two different characters in a string and check if their counts are equal
string count_chars(string str, string chr1, string chr2) {

	int ctr1 = 0, ctr2 = 0; // Initializing counters for chr1 and chr2 occurrences

	// Loop through the string to count occurrences of chr1 and chr2
	for (int x = 0; x < str.length(); x++) {
		if (str[x] == chr1[0]) // Checking if the current character matches chr1
			ctr1++; // Increment counter for chr1 occurrences

		if (str[x] == chr2[0]) // Checking if the current character matches chr2
			ctr2++; // Increment counter for chr2 occurrences
	}

	// Check if the counts of chr1 and chr2 are equal and return True or False accordingly
	if (ctr1 == ctr2) {
		return "True"; // Return "True" if counts of chr1 and chr2 are equal
	}
	else {
		return "False"; // Return "False" if counts of chr1 and chr2 are not equal
	}
}

// Main function
int main() {
	// Output the result of counting occurrences of characters in different strings
	cout << count_chars("aabcdeef","a","e") << endl; // Output: True
    cout << "\n" << count_chars("aabcdef","a","e") << endl; // Output: False
    cout << "\n" << count_chars("aab11cde22f","1","2") << endl; // Output: True
	return 0; // Return 0 to indicate successful completion
}

Sample Output:

True

False

True
