Assignment operator chain

Here we demonstrate the assignment done in a chain fashion.

Learning Objectives

  • Learning successive assignment or chained assignment.

Source Code

TC++ #5511

 

Source Code

Run Output

10 10 10

Code Understanding

int x,y,z;
Here we declare three integer type variables.

x=y=z=10;
This is assignment in chained fashion. First z is assigned a value as 10 then y is assigned value in z and then x is assigned value in y.

cout<<x<<” “<<y<<” “<<z<<endl;
This will print all values as 10.

Notes

  • While using assignment and composite assignments, care must be taken that the value assigned fits the data size of target data type like int, float, long, char etc.

Common Errors

  • Successive assignments while declarations will not work. For. e.g. int x=y=z=10;   will not work as this means that while x  might be treated as declared but the other two will not be. This will also lead to compiler errors.
