Answer:
The first automatic digital computer has been designed by the English mathematician and inventor Charles Babbage. Babbage developed the Analytical Engine Plans for the mid-1830s.
Explanation:
- Babbage has developed the concept of a digital, programmable computer and was a mathematician, philosopher, inventor, and mechanical engineer.
-
Some regard Babbage as a "computer father"
-
The inventing of its first mechanical computer, the difference engine, is attributable to Babbage, which eventually resulted in more complex electronic designs, although Babbage's Analytical Engine is the main source of ideas for modern computers. He was described as the "prime" among the numerous polymaths of his century by his varied work in another field.
difference between engineering and architecture are.
A engineer is a person whose job involves designing and building engines, machines, roads, bridges ,etc .
While architect design buildings only.
Answer:
B. 1 6 3
Explanation:
Given function definition for calc:
void calc (int a, int& b)
{
int c;
c = a + 2;
a = a * 3;
b = c + a;
}
Function invocation:
x = 1;
y = 2;
z = 3;
calc(x, y);
cout << x << " " << y << " " << z << endl;
- Since x is passed by value, its value remains 1.
- y is passed by reference to the function calc(x,y);
Tracing the function execution:
c=3
a=3
b=c+a = 6;
But b actually corresponds to y. So y=6 after function call.
- Since z is not involved in function call, its value remain 3.
So output: 1 6 3
I do not know spanish please say in english
Answer:
Constructor issue
Explanation:
When you look at the Class A, the constructor takes one argument as a parameter, a String.
A(String newS) {
s = newS;
}
However, in the main, the constructor does not take any argument as a parameter.
A a = new A();
That's why the code does not compile.
