My program keep showing me the message 1951951802

[Petrusel]

my problem was to slove the ecuation (a+b+c)/(a+c)-(1/a)
and my code is

#include <iostream>

using namespace std;

int main()


{
    int a, b, c, ex;
    cout<<"a= "<<endl;
    cin>>a;
    cout<<"b= "<<endl;
    cin>>b;
    cout<<"c= "<<endl;
    cin>>c;
    if ((a==0)or(a+c==0)) cout<<"Ex dosent make sens"<<endl;

        else ex==((a+b+c)/(a+c))-(1/a);
        cout<<"Value of expresion for a="<<a<<"b="<<b<<"c="<<c<<"is "<<ex<<"."<<endl;


    return 0;
}

and my program keep showing me the result is 1951951802

Use = for assigning the value of the expression to the variable.
The == operator is for comparing if two things are equal. It doesn't modify anything.

thanks you, but one question... if i insert the value for example a=1
b=1
c=1
after compile and run it show me the vlaue 0... it suposed to show 0,5... what i can do?

else ex==((a+b+c)/(a+c))-(1/a);
should be
else ex=((a+b+c)/(a+c))-(1/a);
(which was Peter87's comment.)


Then
int a, b, c, ex;
should be
double a, b, c, ex;
or you will be subject to integer division ( 3/2 gives ... 1 yes, really!)
