Assignment Operators in C++
Notes:
Assignment Operators in C++ Programming Language:
Assignment Operator: ( = )
- is used to assign value to a variable or a constant
Short Hand Assignment (SHA) Operators:
- allow us to write compact or condensed form assignment statements
AA (Arithmetic Assignment)
+=
-=
*=
/=
%=
BA (Bitwise Assignment)
&=
|=
^=
<<=
>>=
Example code:
#include <iostream>
using namespace std;
int main()
{
const float PI = 3.142;
cout << PI << endl; // 3.142
int a = 0;
cout << a << endl; // 0
a = 10;
cout << a << endl; // 10
a += 10; // a = a + 10;
cout << a << endl; // 20
a -= 10; // a = a - 10;
cout << a << endl; // 10
a *= 2; // a = a * 2;
cout << a << endl; // 20
a /= 2; // a = a / 2;
cout << a << endl; // 10
a %= 2; // a = a % 2;
cout << a << endl; // 0
return 0;
}
