Question

Hello
I'm still just starting out in programming and I have a small problem... I want to know what to write to create a program that asks for the absolute value of a number... Thank you for replying quickly.

Hi,  The absolute value of a number is the number in positive no matter what, right?  So it's simple, in algorithm it would look like: If (number < 0) then number := 0-number End If

Hi,
In most programming languages, there is a predefined function in that language that returns an absolute value:
If you use the C language, it would normally look like (if I remember the exact syntax correctly):
absolute_number=abs(number).
Of course, an absolute number is the positive value of the number in question.

Thank you for your help....but what this little problem is about the C language and I was told that I need to use if and else. I don't know how, but thank you anyway for your help..

In fact, the absolute value of a number is the number itself without the sign. Saying that it is the positive value of the number implies a notion of relativity.

Kilian provided the algorithm, so to use it in C, just transcribe it...  -- Ferrets dominate the world! Homer and Bender are gods, let's worship them as they deserve...

However, my thing only works with integers; it won't work with reals.

Hello and welcome to the world of programming. I'm happy to respond to you because I am also, like you, a pretentious beginner.
Here’s a little code that you can try as simply as possible.

#include <iostream>

int main()
{
int number;

std::cout<<"Enter a number: ";
std::cin >>number;
if (number<0)
{
number = -number;
}
else
{
number = number;
}
std::cout<<"Its absolute value is: "<<number<<std::endl;
return 0;
}
