Hello DaniWeb, I am pretty new to this community and overall to the C++ language. Not so long ago i've decided to learn C++.
Anyways the problem is:
I am trying to make a simple calculator, its very easy my problem is i am trying to advance my knowlege about the structure so i was trying to make a calculator using only structure based variables, my question is:
When i take a normal integer variable for example:
int x,y,z;
z=x+y;would compile correctly
but
if i would make a structure called database example:
struct database{ int x,y,z};
database get;
get.z=get.x+get.y;would not be correct how can i make it correct if possible?
Here is the source code i've made so far:
#include<iostream>
#include<conio.h>
using namespace std;
struct database{/*Structure start.*/
int loop;
string choice,var1,var2,combined;
};/*Structure ends.*/
database calc(database get);
int main(){
database get,*p;
p=&get; /*Point's the pointer into the database. just testing*/
get.loop=0;
while(get.loop<1){
/*First question*/
cout<<"Welcome to the <M>aster <B>laster Calculator!\nPlease type one of the words below afterwards press enter.\nPlus\nMinus\nMultiple\nDivide\n\nChoice:";
/*Input of choices*/
cin>>get.choice;
calc(get);
}
}
database calc(database get){
if((get.choice=="Minus")||(get.choice=="minus")){
cout<<"Please choose the first number:";
cin>>get.var1;
cout<<"Please choose the second number:";
cin>>get.var2;
get.var1=get.var1-get.var2; //<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<Error occurs here!!
cout<<"\nThe answer is:"<<get.var1<<"-"<<get.var2<<"="<<"\n";
}
}I've marked where the compiler Dev-C++ bloodshed see the errors by a comment(in line 43).
Thank you for all the contributors and have a good day.
