Incorrect average

[cmccmc]

Why doesn't this code calculate the correct average?
For example when the average should be 3 it displays 7

#include <iostream>
using namespace std;
int main()
{
	char Name1 [15];
	char Name2 [15];
	char Name3 [15];
	int ID1;
	int ID2;
	int ID3;
	float Mark1;
	float Mark2;
	float Mark3;
	cout<<"Enter The First Students Information\n";
	cout<<"Name: ";
	cin>>Name1;
	cout<<"ID: ";
	cin>>ID1;
	cout<<"Mark: ";
	cin>>Mark1;
	cout<<"Enter The Second Students Information\n";
	cout<<"Name: ";
	cin>>Name2;
	cout<<"ID: ";
	cin>>ID2;
	cout<<"Mark: ";
	cin>>Mark2;
	cout<<"Enter The Third Students Information\n";
	cout<<"Name: ";
	cin>>Name3;
	cout<<"ID: ";
	cin>>ID3;
	cout<<"Mark: ";
	cin>>Mark3;
	cout<<Name1<<" "<<ID1<<" "<<Mark1<<"\n";
	cout<<Name2<<" "<<ID2<<" "<<Mark2<<"\n";
	cout<<Name3<<" "<<ID3<<" "<<Mark3<<"\n";
	float Average=Mark1+Mark2+Mark3/3;
	cout<<"The Average Mark is "<<Average;
	cin.ignore();
	cin.get();
}

Think of your operator precedence. Division comes before addition so on line 38 you are dividing Mark3 by 3 and then adding Mark1 and Mark2 to that. Modify line 38 to:

float Average=(Mark1+Mark2+Mark3)/3

Change it to float Average= (Mark1+Mark2+Mark3) / 3; Other wise it would be calculating (Mark3 / 3) + Mark1 + Mark2.

Thats odd - I wrote that when there was no post there. Maybe the submit lagged lol.

okay I forgot about the order of operations
edit: worked perfectly Thanks!
