For Loop Use Cases

It's true that 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

generating

implementing

calculations


              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!
