C++ a beginner understand

When writing a simple HelloWorld program it's is a step towards a higher call. A world of imagination an complicated creativity 😛

#include <iostream>
int main()
{
    std::count << "Hello, World!" << std::endl;
}

I understand now that this small program could also have been written in a not so readable way

#include <iostream> int main(){std::count<<"Hello, World!"<< std::endl;}

It is not very readable for a human being to quickly make sense of the program

In a human readable program you have spaces, indentations, line shift and one of the most fundamental of programming is giving your code a visual structure and it doesn't matter which programming language your writing because you have to consider that at some point someone will read your code, copy your code, debug your code, and if you write "obviousVariableNames" you can save a lot of commenting 😆

I still feel like a beginner who is trying understand some of the most basic things like loops, variables, if/else statements, switch, function, objects, opp.. and classes what the hell is that?
Yes.. I'm still learning and will never stop learning. It's a struggle, a hard learning student who keeps on struggling until he meets gratification and satisfaction of a programming language.

With great powers comes great responsibility.. what a geek but he got a point.

C++ using while loop to sum the numbers from 50 to 100

This exercise is from the C++ primer 4th edition book from 2005. The program works and runs fine. This is a solution to the exersice section 1.4.2 on page 17.

Exercise 1.10: Write a program that uses for loop to sum the numbers from 50 to 100. Now rewrite the program using a while loop.

In this part we rewrite the for loop to using a while loop

Exercise 1.10: Write a program that uses for loop to sum the numbers from 50 to 100. Now rewrite the program using a while loop.
💥 Beware: This is not just a simple program that adds two numbers together. It is a little bit more complicated than that.

C++ using while loop to countdown from 10 to 0

Solution for the book C++ Primer 4th edition 2005. Page 17. Exercise 1.11

Hello and welcome to this blog post today we are going to make a solution for the exercise 1.11 on page 17 in C++ primer fourth edition book from 2005.

Exercise 1.11:
Write a program using while loop to print the numbers from 10 to down to 0.
Now rewrite the program using for loop.

While loop - Solution

#include <iostream> 

int main()
{
 int i = 11;
 int counter = 0;
 while (i > counter)
 {
  i--;
  std::cout << i << std::endl;
 }
 return 0;
}

For loop - Solution

#include <iostream>
int main()
{
 int counter = 0;

 for (int i = 10; i >= counter; i--)
 {
  std::cout << i << std::endl;
 }
 return 0;
}
