Meet Johnathan MK, the best student with creativity in diib Academy on a concluded training on web programming.

He created a portfolio website project with HTML5/CSS3.

#diibacademy

diib™️ Nigeria launched an initiative through diib™️ Academy, a non-profit organisation and a subsidiary of diib™️ Nigeria to equip Youth nationwide on technology Skills involving:

~ Web Programming
~ System Programming
~ Machine Learning
~ Data Science
~ Robotics
~ Artificial Intelligence


diib Academy extends tech skills to Taraba State, Donga LGA, Mararraba Town. In vision with Federal Government to reduce unemployment in the country and boost economy value through exporting technology to other countries.



diib Academy just concluded the first-batch Web Programming training in Mararraba Town, equipping over 18 youths. Most of the students develop and hosted a portfolio website as a side project using HTML5/CSS3 and Javascript.


Currently second-batch training has commenced since last week to equip more youths. diib Academy also equip NYSC Corp member in Mararraba Town on tech skills.


diib Academy is willing to export and extend ICT skills across the country, where passionate folks are ready to learn tech skills. To battle unemployment, economic problem and boost technology in the country.

chrisUmendeche:
Am already in for this......No turning back..Have made up my mind long time ago...Have given up things which many of you here can't..

I totally agree with you

Tim1212:
#include <iostream>

using namespace std;

int main()
{
int f;
int c;

cout << "Enter temperature in Fahrenheit: ";
cin >> f;
cout << endl;

c = static_cast<int>( 5.0 / 9 * (f - 32));

cout << f << " degree F = " << c << " degree C. "
<< endl;

return 0;

}

This program is applied in thermometer

Tim1212:
#include <iostream>

using namespace std;

int main ()
{
int length;
int width;
double perimeter;
double area;

length = 6;
width = 4;
perimeter = 2 * ( length + width );
area = length * width;

cout << "Length = " << length << endl;
cout << "width = " << width << endl;
cout << "Area = " << area << endl;
cout << " Perimeter = " << perimeter << endl;

return 0;
}

I will be explaining every single program starting from the beginning

chukxy:
@Tim1212, quick question for you. Why should we implement our own custom copy constructor in a class instead of using the default copy constructor in a class in C++. If you explain this with example, I will appreciate.

Secondly, why is the advantage of using heap memory over stack memory in c++? Again, I will appreciate if you explain with example.

Many thanks in anticipation.

What you asked is beyond the scope of this thread, though you have been cleared by others.

Ask question pertaining to the C++ programs we have here.

Pick anyone, then we start from there
