What is wrong with my program?

Question

#include <iostream>
#include <cmath>
using namespace std;

int x;
int y;
int z;

int main() {
cin >> x;
cin >> y;
x+y >> z;
cout << z;
return 0;
}

Answer 1

z=x+y and x+y=z have different meaning in c++?

Answer 2

x+y >>z ?
do you want assign x+y to z?
right way to do it is:
z = x +y;

Answer 3

cin >> x;
cin >> y;
x+y >> z; //wrong!!!
z=x+y ;
cout << z;
a point about >>
look this code.....
#include<iostream>
using namespace std;
int main(){
int a = 10;
int b = (a>>1); // you can also use (a/2)
cout<<b;

return 0;
}

Answer 4

if you want to store them in double or float variables, there is no need to do something extra:
int a =5;
double b= a;

also if you want only to use an integer as double, just use it. compiler will consider it as double;

or you can easily change any integer to double by multiply it by 1.0

Answer 5

Try z=x+y

Answer 6

gave an error.

Answer 7

put int values INSIDE main ()

Answer 8

What I have to do, if I want to change integer numbers to double float-pointed numbers?

Answer 9

x+y>>z should be z=x+y;

Answer 10

put x+y =z;
it will work

Answer 11

declate x,y,x inside the curly brackets, after the "int main()" declaration

Answer 12

#include <iostream>
#include <cmath>
using namespace std;

int main() {

int x;
int y;
int z;

cin >> x;
cin >> y;
x+y = z;
cout << z;
return 0;
}
