odd numbers 1 to 100

Here is a C++ code snippet that prints the odd numbers from 1 to 100, along with explanations for each step:

#include <iostream>

int main() {
    // Iterate through numbers 1 to 100
    for (int i = 1; i <= 100; i++) {
        // Check if the number is odd
        if (i % 2 != 0) {
            // Print the odd number
            std::cout << i << std::endl;
        }
    }

    return 0;
}

Explanation:

1. #include <iostream>: This line includes the iostream library, which provides input/output functionality in C++.

2. int main(): This is the main function where the program execution starts.

3. for (int i = 1; i <= 100; i++): This for loop iterates through the numbers 1 to 100. i is initialized to 1, the loop continues as long as i is less than or equal to 100, and i is incremented by 1 after each iteration.

4. if (i % 2 != 0): This if statement checks if the current number i is odd. The modulus operator % calculates the remainder when i is divided by 2. If the remainder is not equal to 0, then the number is odd.

5. std::cout << i << std::endl;: This line prints the odd number i to the console. std::cout is the standard output stream, and << is the stream insertion operator used to output values. std::endl is used to insert a newline character at the end of each output.

6. return 0;: This line indicates the end of the main function and returns 0, which is the standard way of indicating successful program execution.

By running this code, you will see the odd numbers from 1 to 100 printed on the console.
