The primary purpose of a for loop is to iterate a predetermined number of times, it's important to note that these loops serve a broader range of applications and they are, in fact, the most frequently used type of loops in programming. Some of their use cases include:

  • Iterating through arrays and collections;
  • Generating sequences of numbers;
  • Implementing repetitive algorithms;
  • Calculations and simulations.

Let's look at the simple examples of these use cases:

iterating.cpp

iterating.cpp

generating.cpp

generating.cpp

implementing.cpp

implementing.cpp

calculations.cpp

calculations.cpp

copy

              
12345678910

            
#include <iostream>

int main() {
    int numbers[5] = {1, 2, 3, 4, 5}; // Static array
    
    // Using a for loop to iterate through the static array
    for (int i = 0; i < 5; i++) {
        std::cout << numbers[i] << " ";
    }
}

As you can see they are used for a wide range of applications, from processing data and performing calculations to controlling program flow and handling complex algorithms. So it's important to get good with them. Let's practice!

You have an array ratings that stores user scores or ratings. Your task is to find the maximum value in this array to determine the highest rating.

All the code should be implemented inside the findMax function.

  1. Initialize the variable maxRating with the value of the first element in the array.
  2. Use a for loop to iterate through the rest of the array, starting from the second element.
  3. Inside the loop, check if the current element arr[i] is greater than maxRating.
  4. If the current element is greater, assign its value to maxRating.
  5. After the loop finishes, return maxRating as the result of the function.
