C++ Exercises: Check if a given string contains between 2 and 4 'z' character
Check 2–4 'z' Characters
Write a C++ program to check if a given string contains between 2 and 4 'z' characters.
Sample Solution:
C++ Code :
#include <iostream>
using namespace std;
// Function to count the occurrences of the character 'z' in the given string
bool test(string str)
{
int ctr = 0; // Counter variable to count occurrences of 'z'
// Loop through each character in the string
for (int i = 0; i < str.length(); i++)
{
// Check if the current character is 'z'
if (str[i] == 'z')
{
ctr++; // Increment the counter if 'z' is found
}
}
// Return true if the count of 'z' is more than 1 and less than 4, otherwise return false
return ctr > 1 && ctr < 4;
}
// Main function
int main()
{
// Output the result of the test function with different input strings
cout << test("frizz") << endl; // Output: 1 (true)
cout << test("zane") << endl; // Output: 0 (false)
cout << test("Zazz") << endl; // Output: 0 (false)
cout << test("false") << endl; // Output: 0 (false)
return 0; // Return 0 to indicate successful execution of the program
}
Sample Output:
1 0 1 0
