Course C Initial 10th – Exercises with If-Else

Lesson 10.

As we see in the previous lesson, now we’ll make some algorithms to practice. Those are 10 questions. I recommend that you make this algorithms because it’ll help you in the future.

1- Make an algorithm that reserves how tall is a person and test this conditions:
  • If the Tall is greater than 1.90, printf (“You can play basketball”);
  • If the Tall is smaller than 1.50, printf (“You’re not taller”);
  • if the Tall is greater or equal to 1.50 and smaller or equal than 1.90, printf (“You’re between arrive”);
2- Make an algorithm that works as a game, it may ask to user “What’s the Spanish Capital?” so the user will have available 4 possibility, they’re respectively a) Madrid, b) Barcelona, c) Vigo, d) Sevilla, after will be tested them. Note: use for store the result, a character type variable.
  • If the variable is equal to ‘a’, so printf (“You’re Wright”);
  • Else, so printf (“You’re wrong”);
3- Make an algorithm that works as a table, so the user type a value and it is stored in a variable. The algorithm is for the user type the result of the sum 985+856 and it’ll be tested.
  • If the user typed 1841, so printf (“The answer is corret”);
  • Else, printf (“Don’t you know sum?”);
4- Make an algorithm that reserves 4 numbers, so test if they’re equal or what’s the larger between them.
5- Make an algorithm that reserves a number, an operator and other number, so calculates the operation solicited. For example: 7*2 is equal to 14, use an int, char and int respectively. Test what operation will be made and print the result.
6- Make an algorithm that reserves the product code and the quantity, so calculate the prices. Note: before defines how you can see below:
  • ‘M’ – Milk – U$ 1,00 1L.
  • ‘P’ – Potato – U$ 2,50 Kg.
  • ‘E’ – Meat – U$ 10,00 Kg.
  • ‘J’ – Juice – U$ 0,50 each.
Use if else to test the options. Note: use a special case for when the code was incorrect. After multiple the price by quantity and print the total price.
7- Make an algorithm that test if a number typed by use is negative, or null, or positive.
  • If Num==0, print “This Number is Null”
  • Else if Num<0, print “This Number is Negative”
  • Else if Num>0, print “This Number is Positive”
8- Make an algorithm that test if a number typed by user is pair or impair. Note: a number is pair only if it’s divisive by 2, else, it’s impair.
9- Make an algorithm that reserves 5 numbers in different variables, so use a variable called Cont to sum the quantity of numbers greater than 0, it may be initialized with 0. Just test if it is greater than 0, so print a message saying the quantity of positive numbers.
10- Make an algorithm that reserves 5 numbers in different variables, so use a variable called Cont to sum the quantity of numbers smaller than 0, it may be initialized with 0. Just test if it is smaller than 0, so print a message saying the quantity of negative numbers.
Well, that’s all folks! In the next lesson, we’ll see the Switch Command! See you later!

Lesson 7. Now, as promised in previous lesson, we’ll go to make some algorithms to practice all knowledge that we learned up to here. First: Make an algorithm that reserves 3 numbers by user and sum them, after show the result. For this, we first make the structure as showed below. How we can see, this is the basic structure of a software in C language. Now, we’ll create the variables for it: Okay, the variables was created. Now we’ll input the values for them with printf’s and scanf’s how you can see below: Note: always use return 0; in the end function. Now we’ll create a new variable called Result that will be the sum of Num1, Num2 and Num3 how you can see below. After we’ll print Result. That’s finished, we have an algorithm that calculates the sum between 3 numbers. Now, practice this algorithm, write and test yourself, test it change the math operators and joyful. You cou

Course C Initial – 3rd Variables Part. 1

Lesson 3 Part. 1. Hello again! As promised in the previous class, now I speak about variables in C language. First, what’s a variable? The answer is important because it will help us to learn more and use them. Definition: capable of being varied or changed; alterable. (source: www.dictionary.com). That’s the definition that we need! So, there’s some variables types in C language. They’re: Global; Locale; Constant; Volatil e; Inside each one of those cases, we have in resume, 4 type that can be represent in each or all those cases. Below, you’ll can see its names. c har – ‘a’, ‘b’, ‘c’,...; int – 1, 2, 4, 7,...; float – 7.553279, 8.856347,...; double – 9.5896324789632, 10.5885569347799,... ; There’s variations inside each format, but we’ll see in the future. How we can see above, the type data that the variables types represent. Char is for character data, int is for integer, float is for floating point

Course Python For Life 3 – Input Command

As was promised in the previous lesson, now we’ll see the input command in python language, it’s a smaller lesson, next lesson, we’ll see variable’s concepts in Python that’s different of others languages. First step: - I recommend that you use the output command. In python, input command requires a variable. There’s two ways to use this command, they’re: - with print. - without print. Note: In python, you don’t need to use ‘;’ in the end of a line, it works, but it isn’t required. With print: print(‘type any key...’) a = input() Test it yourself! See it in the editor: Run and see what happen. It required that the use type any thing by the keyboard. Below, see it being ran. But there’s other way to do this code, see below: a = input(‘Press any key...’) Test it yourself! Think about it, that’s the way to learn! The appearance is:
