Getline Help

[365X92yv]

I need some help to be able to input a line of text such as.....

1/2 + 4/3 - (3/2 * 1/3)

and calculate it. I'm trying to use getline but I either don't understand the compiler errors or I don't use the right parameters. Thanks a bunch for the help.

post the code (in tags please) so we can see what are you doing wrong

int fracInput()
{

int fracTop, fracBot;
char fracSign;
string fraction;

cin.getline(fraction, 30, '/');
cout << fraction;
}

What I want is to read the whole line and be able to store the numerator in fracTop the operator in fracSign, and the denominator in fracBot.

-----------------------------------------------------------------------------------------------------------------
Write a program to do fractional arithmetic. The program should handle the operations of addition, subtraction, multiplication, and division. It should also reduce the answer to its lowest form (e.g. 3/9 should be 1/3). The user should be allowed to enter any number of problems.

where are you getting the fractions from?

[365X92yv]

I'll be inputting them using the iostream. The fractions are going to be user input.

should look somethin like this havn't tested this but should work

#include <istream>
#include <iostream>
#include <cstdio>
#include <cstdlib>

using namespace std;





int iNumerator;
	char cOperator;
	int iDenominator;
	//char cPlus[] = "+";
		//char cMinus[] = "-";
		//char cMult1[] = "x"; 
		//char cMult2[] = "X";
		//char cMult3[] = "*";
		//char cDivide[] = "/";
		

 int calculator(int iNumerator,int iDenominator)
{
	
  cout <<iNumerator / iDenominator;

//cin.getline(fraction, 30, '/');
//cout << fraction;
}


main()
{
	cout << "enter numerator" end1;
cin >> iNumerator;

cout << "enter denominator";

cin >> iDenominator;

calculator(iNumerator,iDenominator);

// or just skip the function (I was writing a calculator not just a divider)  and delete function call an just write cout << iNumerator / iDenominator;

// add pause here havn't gotten that far...

// this is good practice for me btw I'm a noob too!!

// Just thought of this, this function will only return an interger value it will NOT include the remainder in the result and it will not return a float value

}

Waiting on your reply Detroit.

My reply?

int fracInput()
{

int fracTop, fracBot;
char fracSign;
//string fraction;
char fraction[30]; //since you are using the C style cin.getline you must use a char array

cin.getline(fraction, 30, '/');
cout << fraction;
}

that will let you at least pull something from the input
