Computer Programming

Preparation

• Group size: individual

• Download and install any C compiler you like and Python interpreter on

your computer. For this purpose, we have videos to show you how to do this

for Python. Regarding C, perhaps the simplest way is to install Dev-C++

(one may download it from its official website: https://www.bloodshed.net/)

if you use Windows. But for Mac users, you may need do some search on

Bilibili, Youtube, or Google to install a C compiler. For example, now

a popular way to program in C on Mac is to use “Visual Studio Code +

gcc”. (Of course, one may also use Visual Studio Code to program in C on

Windows.)

• One may also use online C/Python compiler/interpreter. But in this way,

the difference between compilers and interpreters becomes less clear.

Aim

In this lab, you will learn how to program a computer. Moreover, you will

understand what is the difference between compiler and interpreter.

Your task

Convert the four flowcharts (i.e. HelloWorld.rap, AbsoluteValue.rap, Sum.rap,

and Search.rap) given to you in our lab on Raptor into C programs and Python

programs, respectively.

Toy examples

I hope that the codes given below cover most syntaxes of C and Python that

are needed for writing down the required programs. You need to combine/adapt

these codes in a new/creative way.

1. How to first read an integer from the keyboard and then print it on the

screen?

C program:

#include <stdio.h>

int main() {

int number;

/* This is a comment that will not be regarded as a part of the program

by the compiler: "number" is a variable. You can change the name "number"

to virtually any other name (as long as it is a concatenation of English

letters and numbers but beginning with a letter) which you prefer to. */

printf("Enter an integer: ");

1

// reads and stores input

scanf("%d", &number);

// displays output

printf("You entered: %d", number);

return 0;

}

Python program:

number = int(input("Enter an integer: "))

print("You entered:", end = " ") # The purpose of "end = " "" is to avoid new line

print(number)

2. A simple if statement

C program:

#include <stdio.h>

int main()

{

int score;

score = 71; // You can change the value of score here to test this program

if (score >= 60)

printf("Pass");

else

printf("Fail");

return 0;

}

Python program:

score = 71

if score > 59:

print("Pass")

else:

print("Fail")

3. A simple while statement

C program:

#include <stdio.h>

2

int main()

{

int i;

int m;

i = 1;

m = 100; // The value of the variable m can be changed to input from the keyboard

while (i != m)

{

printf("%d ", i);

i = i + 1;

}

return 0;

}

Python program:

i = 1

m = 100

while i <= m:

print(i, end = " ")

i = i + 1

4. How to initialize an array of integers?

C program:

#include <stdio.h>

int main()

{

int a[100];

int i;

i = 0;

while (i < 100) // Note that the index of arrays begins with 0 (as opposed to 1)

{

a[i] = 0;

printf("a[%d] = %d ", i, a[i]);

i = i + 1;

}

return 0;

}

3

Python program:

i = 0

a = []

while i <= 99:

a.append(0)

print("a[", end = "")

print(i, end = "")

print("] = ", end = "")

print(a[i], end = " ")

i = i + 1
