New at coding (C++)
Currently following a book to get a bit of an introduction towards coding / C++ stumbled upon this exercise:
Exercise 1.6: Explain whether the following program fragment is legal:
If the program is legal, what does it do? If the program is not legal, why
not? How would you fix it?
I got the program to work and tell me what the sum is of v1 + v2 in following code.
'
Altough i first have to press a random letter/symbol and enter before it shows me the sollution of 3 + 9, Anyone knows why it does that?
I'm using Visual studio 2017
Thanks.
EDIT
I figured out line 5: std::cin >> v1 >> v2; was causing it because it reads the input. Why is that in this situation?
Exercise 1.6: Explain whether the following program fragment is legal:
Code:
std::cout << "The sum of " << v1;
<< " and " << v2;
<< " is " << v1 + v2 << std::endl;

Code:
#include <iostream>
int main()
{
int v1 = 3, v2 = 9;
std::cin >> v1 >> v2;
std::cout << "The sum of " << v1
<< " and " << v2
<< " is " << v1 + v2 << std::endl;
return 0;
