Loops allow you to repeat a block of code multiple times until a condition is met. C++ supports three types of loops: for, while, and do-while.

• for loop: Executes a block of code repeatedly for a fixed number of times.

                     for (int i = 0; i < 5; i++) {
                           cout << i << ” “;
                     }

• while loop: Executes a block of code repeatedly as long as a condition is true.

                     int i = 0;
                     while (i < 5) {
                           cout << i << ” “;
                           i++;
                     }

• do-while loop: Similar to a while loop, but the block of code is executed at least once before the condition is checked.

                                       int i = 0;
                                       do {
                                              cout << i << ” “;
                                              i++;
                                       } while (i < 5);
