Answer:
Explanation:
The missing program is given below
var a = 3;
var b=7;
var c = 10;
a=a+b;
b=a+b;
c=a+b;
console.log("a:" + a + "b:" + b+"c:" + c);
In the program a is assigned a value 3, b is assigned a value of 7, c is assigned a value 10;
a = a+ b; so here a = 3+7 = 10. New value of a = 10
b = a+b; so here b=10+7 = 17. New value of b = 17
c = a+ b; so here c = 10 + 17 = 27. New value of c = 27
So the final line will log a = 10, b = 17, c = 27.
