Explain different types of loops in C with examples.

C provides three primary types of loops to perform repetitive tasks: for, while, and do-while loops.

• For Loop: The for loop is used when the number of iterations is known beforehand. It has three parts: initialization, condition check, and increment/decrement. Example:

  for (int i = 0; i < 5; i++) {
  printf(“%d “, i);
  }
  // Output: 0 1 2 3 4

• While Loop: The while loop repeats as long as the specified condition is true. The condition is checked before the execution of the loop’s body. Example:

  int i = 0;
  while (i < 5) {
  printf(“%d “, i);
  i++;
  }
  // Output: 0 1 2 3 4

• Do-While Loop: The do-while loop guarantees that the body of the loop is executed at least once. The condition is checked after executing the loop body. Example:

  int i = 0;
  do {
  printf(“%d “, i);
  i++;
  } while (i < 5);
  // Output: 0 1 2 3 4

Each loop type is useful in different scenarios depending on whether the number of iterations is known in advance or whether the loop should always execute at least once.
