Challenge: Common Use Cases of The For Loop in C++
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
generating.cpp
implementing.cpp
calculations.cpp
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.
- Initialize the variable
maxRating
with the value of the first element in the array. - Use a
for
loop to iterate through the rest of the array, starting from the second element. - Inside the loop, check if the current element
arr[i]
is greater thanmaxRating
. - If the current element is greater, assign its value to
maxRating
. - After the loop finishes, return
maxRating
as the result of the function.
