Explanation
The provided code is a C++ program that demonstrates the use of shortcut operators. It includes the iostream
library, which is used for input/output operations, and the std
namespace is being used.
The main
function is the entry point of the program. It initializes ten integer variables num1
through num10
with values from 1 to 10 respectively.
int num1 = 1;
int num2 = 2;
// ...
int num10 = 10;
The program then demonstrates the use of various shortcut operators. The +=
operator adds the value of num2
to num1
and assigns the result to num1
. The -=
operator subtracts num4
from num3
and assigns the result to num3
. The *=
operator multiplies num5
by num6
and assigns the result to num5
. The /=
operator divides num7
by num8
and assigns the result to num7
. The %=
operator calculates the remainder of num9
divided by num10
and assigns the result to num9
.
num1 += num2;
num3 -= num4;
num5 *= num6;
num7 /= num8;
num9 %= num10;
Finally, the program prints the values of num1
, num3
, num5
, num7
, and num9
to the console using the cout
object and the <<
operator, which is used to send output to the standard output device (usually the screen).
cout << "num1 = " << num1 << endl;
// ...
cout << "num9 = " << num9 << endl;
The endl
manipulator is used to insert a new line. The program ends by returning 0, indicating successful execution.
Output
num1 = 3
num3 = -1
num5 = 30
num7 = 0
num9 = 9
Process finished with exit code 0
