100 Days Coding Challenge - Day 5/100 [Learning c++]

As a programmer, everyday I set out to fix new problems and overcome challenges in programming, today wasn't an exception... When I got up this morning, My code had bugs all over and they were practically invincible.

What did I do today

---

So first of all I continued my c++ classes today and I worked with methods and functions, successfully wrote a method and it worked. Yeeah it was a simple method to add two integers for a test.

Below is the c++ program;

# import <iostream>
using namespace std;

int sum(){
    int total = 2+2;
return total;
}

int main(){
    
    
    int x = sum();
cout << (x);
}

The method in the program is int sum() once this method is called, it returns an integer value which can be stored and displayed for the user. The method can also be modified to accept two variables x and y from the user, any operation can now be carried out on the values.
This will make the program look like this:

# import <iostream>
using namespace std;

int sum(int x, int y){
int total = x+y;    
return total;
}

int main(){

int total = sum(7,10);

cout << (total);
}

Next Up
My software started giving me issues with pulling data from the database, it just kept giving a thousand lines of error codes, partly my fault due to the fact that I didn't ask it to print the real error, I needed to understand my code more so I did the fault finding myself and at the end of the day... Problem fixed.
Had to do that because I read a quote by John Woods

Always Code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live
Basically, I don't want someone slitting my throat because of bad code, so I'll go an extra mile to see that it doesn't happen.

What I Learnt

---

At the end of the day today, I learnt how to:

• Create c++ function
• Understand my code errors more by commenting different lines out to know where the fault is coming from.

Quick Announcement

I would be making my Hotel management software open source in a week from now, developers and graphic designers are welcome to join the team!!!

See Y'all soon
