C++ Loop

C++ provides different types of loops to iterate over a set of statements.

1. for loop:
It is used to execute a set of statements for a fixed number of times.

Example:

#include 

using namespace std;

int main() {
   for(int i=0; i<5; i++) {
      cout << i << endl;
   }
   return 0;
}

Package/Library: Standard C++ Library

2. while loop:
It is used to execute a set of statements as long as the specified condition is true.

Example:

#include 

using namespace std;

int main() {
   int i=0;
   while(i<5) {
      cout << i << endl;
      i++;
   }
   return 0;
}

3. do-while loop:
It is used to execute a set of statements at least once, and then continue to execute as long as the specified condition is true.

Example:

#include 

using namespace std;

int main() {
   int i=0;
   do {
      cout << i << endl;
      i++;
   } while(i<5);
   return 0;
}

4. range-based for loop:
It is used to loop over the elements of an array or any other iterable object.

Example:

#include 

using namespace std;

int main() {
   int arr[] = {1, 2, 3, 4, 5};
   for(int i : arr) {
      cout << i << endl;
   }
   return 0;
}
