Programming 8 (final)

Today, in economics, we discussed about health in developing countries and obesity in developed countries. This is one of the global issues today, so I created a program to calculate the Body Mass Index (BMI) to help people identify their BMI.

I employed all of the techniques learnt throughout the project e.g. if, printf, scanf.

Additional learning outcomes
Engaged with issues of global importance – obesity and underweight in the world

Source Code:
#include <stdio.h>

int main(void)
{
double a, b;
puts("Body Mass Index Calculator");
puts("Enter your weight and height");
printf("Weight:"); scanf("%lf", &a);
printf("Height (m):"); scanf("%lf", &b);

printf("Your BMI – %.1f",  a/(b*b));

if(a/(b*b) < 18.5)
puts("Underweight");
else if(a/(b*b) >= 25)
puts("Obese");
else
puts("Normal range");

return(0);
}

Tutor (Final)

As I mentioned last week, today is my last day of this tutor project.

I initiated this project since the 1 October, 2012 and I had three students in total. While I began with just one student, other parents who heard how much my student had improved offered me more work as a private tutor. I believe that this success was the result of my efforts to improve my teaching skills and the quality of my lessons. Through this experience I have learnt the importance of preparation in order to maintain a high standard, as well as how to think from my students’ point of view so that they could get the most out of our study sessions.

Throughout the project I have learnt many things, e.g. the importance of continuous improvement. In terms of CAS learning outcomes, I believe that I have met most of the objectives.

Increase awareness of your strengths and areas for growth – since Maths was one of my strongest subjects, I enjoyed teaching it and I felt I have deepening my understanding of basic concepts by teaching. In my opinion,  teaching someone is the shortest way to learn things because in order to teach, I have to understand it first, and this gives a subconscious pressure that motivates me to learn.

Undertake new challenges – this was my first time to work as a tutor. 

Planned and initiated activities – I always prepare some textbooks or other teaching materials for my students and this preparation was an essential part to sustain a high quality lesson.

Worked collaboratively with others – since I only had an hour to teach, a good communication is required in order to use time effectively. In addition, good communication helped me to think from my students’ point of view, which leads to better understanding.

Shown perseverance and commitment in their activities – teaching every week wasn’t an easy task, however, I have succeed to compile my project.  

Engaged with issues of global importance – as I mentioned in my other posts, we sometimes discussed about global issues, such as global warming, poverty, and cultural discrimination, to practice my students’ speaking skills.

Developed new skills

Programming 7

This program enables a user to input a value and evaluates whether the number is a multiple of 3.

Source code:
#include <stdio.h>

int main(void)
{
int a;

puts("３の倍数かを判定します");
puts("数字を入力してください");
scanf("%d", &a);

if(a%3)
printf("%dは3の倍数じゃないです", a);
else
printf("%dは3の倍数です", a);

return(0);
}

Programming 6

This program enables a user to enter a number and it shows the absolute value.
I used printf, scanf, and if function.

Source code:
#include <stdio.h>

int main(void)
{
double a;
puts("数字を入力してください");
scanf("%lf", &a);

if(a>=0)
printf("絶対値は%lf", a);
else
printf("絶対値は%lf", -a);

return(0);
}

Programming 5

This program enables a user to input two values and it display the bigger one.
I used the if function to evaluate the two numbers

Source code:
#include <stdio.h>

int main (void)
{
int a,b;

puts("二数の大きい方を表示します。");
printf("整数1:"); scanf("%d", &a);
printf("整数2:"); scanf("%d", &b);

if(a>b)
printf("整数1のほうが大きいです。");
else
printf("整数2の方が大きいです。");

return(0);
}

Programming 5

This program enables a user to input three numbers and it displays the biggest number.

Techniques used:
max1=(n1 > n2) ? n1 : n2;
max2=(max1 > n2) ? max1: n3;

The code:
#include <stdio.h>

int main(void)
{
int n1, n2, n3, max1, max2;

puts("３つの整数を入力してください。");
printf("整数1: "); scanf("%d", &n1);
printf("整数2: "); scanf("%d", &n2);
printf("整数3: "); scanf("%d", &n3);

max1=(n1 > n2) ? n1 : n2;
max2=(max1 > n2) ? max1: n3;

printf("最大値は%dです\n", max2);

return(0);
}
