Print Fraction In Dev C++

 

Resize boot camp vm mac os Hi I am having issues trying to resize my Mac OS partition, I previously had a very large recovery partition almost 100gb as a result of removing my linux installation, I since resized this to 650mb.

C++ Syntax

Let's break up the following code to understand it better:

Example

A FP number is a fraction, by definition: A FP number consists of two integers, a mantissa m and an expontent e (and a sign, but that's irrelevant here). So each FP number is really a pair (m,e), and the value f it represents is f=mb^e (where b is a fixed integral base, usually 2). C Arithmetic Operators. Perhaps you have warm memories of doing arithmetic drills in grade school. You can give that same pleasure to your computer. C uses operators to do arithmetic. It provides operators for five basic arithmetic calculations: addition. C - Input and Output - When we say Input, it means to feed some data into a program. An input can be given in the form of a file or from the command line. C programming provides a set. C, C Program to Print Square of a Number; C Program to Print 1 to 100 Numbers using Loop; C Program to Print Even Numbers between 1 to 100 using For and While Loop; Find Intersection of Two Arrays - C, C Program; C, C Program to Check whether an Input Number is a Perfect Square or not; Linear Search Program in C, C - Algorithm, Time Complexity. Sep 30, 2006  Fractions, such as 1/2 2/3 etc. Are not stored in doubles or floats or ints. They are actually formulas. The values you can store are 0.5 and 0.6666 however. If you want to be able to put in fractions, such as 12 1/2 then you will need to parse the string and do the math yourself. If I wanted to do this I would look for a space in the string.

Have a look at the Rectangle drawing function prototype below and then we will look forward to how it is used. Printing float values with fixed number of decimal places through cout in C Here, we will learn how to print float value with fixed number of decimal places using cout in C program? Cout prints a floating pointer number with a maximum of 6 decimal places (some compilers may print 5 decimal places) by default (without trailing zeros).

#include <iostream>
using namespace std;
int main() {
cout << 'Hello World!';
return 0;
}

Example explained

Line 1:#include <iostream> is a header file library that lets us work with input and output objects, such as cout (used in line 5). Header files add functionality to C++ programs.

Line 2:using namespace std means that we can use names for objects and variables from the standard library.

Don't worry if you don't understand how #include <iostream> and using namespace std works. Just think of it as something that (almost) always appears in your program.

Line 3: A blank line. C++ ignores white space.

Line 4: Another thing that always appear in a C++ program, is int main(). This is called a function. Any code inside its curly brackets {} will be executed.

Line 5:cout (pronounced 'see-out') is an object used together with the insertion operator (<<) to output/print text. In our example it will output 'Hello World'.

Note: Every C++ statement ends with a semicolon ;.

Note: The body of int main() could also been written as:
int main () { cout << 'Hello World! '; return 0; }

Remember: The compiler ignores white spaces. However, multiple lines makes the code more readable.

Line 6:return 0 ends the main function.

Line 7: Do not forget to add the closing curly bracket } to actually end the main function.

Omitting Namespace

You might see some C++ programs that runs without the standard namespace library. The using namespace std line can be omitted and replaced with the std keyword, followed by the :: operator for some objects:

Example

#include <iostream>
int main() {
std::cout << 'Hello World!';
return 0;
}

It is up to you if you want to include the standard namespace library or not.


these are the instructions for the program.

Prepare the Fraction class as we discussed in the classroom. It should include three constructors -- one with no parameters and which creates the fraction 0/1, one with one parameter numer and which creates the fraction numer/1, and one with two parameters and which creates the fraction numer/denom, but which assures that the fraction will be in normalized form (that is, positive denominator and with the greatest common divisor removed from the numerator and denominator). Make sure that the store method also stores fractions in normalized form. Add two public methods (functions) to the class, called getNumerator and getDenominator, that return the values of the numerator and denominator of the fraction. The header file and implementation files should be separate files!!

Write a main program to test the fraction class. This main program should first create three fractions to test the three types of constructors. Have the fractions print themselves, but precede each with an explanatory remark so that a fraction doesn't appear by itself. Then prompt the user to enter a numerator and a denominator. Store that fraction in the fraction that you first created with no parameters. Have it print itself. Ask the user if he/she wants to enter another fraction. If N or n is answered, then quit this part of the program and go on to the final step (below). If Y or y is entered, then ask for another fraction, store it and print it. Repeat until the user answers N or n, and then move to the final step. (If the user enters a zero denominator, the constructor and the store method should detect this and take an exit from the program.) As a final step, create the three fractions fract1, fract2 and fract3, where fract1 contains 5/6, fract2 contains 7/2 and fract3 is just the default fraction. Use the getNumerator and getDenominator functions to obtain the numerators and denominators of fract1 and fract2, and store in fract3 the sum of fract1 and fract2. Note: a/b + c/d = (ad + cb) / (b*d). Then have fract3 print itself to make sure the correct result was stored.

could anybody help me out with what you see im missing. i am getting overwhelmed and maybe with a few good pointers i can get set right again thanks

Next time u ask a question don't just post ur kode and say help me with the missing parts? Pin point an exact problem. Then we mite help u?
