<u>Explanation:</u>
Hey there! you need not to panic about it ,your program didn't have Driver program i.e main program! the correct & working code is given below:
// C++ program to count even digits in a given number .
#include <iostream>
using namespace std;
// Function to count digits
int countEven(int n)
{
int even_count = 0;
while (n > 0)
{
int rem = n % 10;
if (rem % 2 == 0)
even_count++;
n = n / 10;
}
cout << "Even count : "
<< even_count;
if (even_count % 2 == 0 )
return 1;
else
return 0;
}
// Driver Code
int main()
{
int n;
std::cin >>n;
int t = countEven(n);
return 0;
}
Answer:
Computer scientists began building rudimentary games and simulations on mainframe computers in the 1950s and 1960s, with MIT's Spacewar! in 1962 being one of the first such games to be played with a video display. The first consumer-ready video game hardware arrived in the early 1970s, with the Magnavox Odyssey, the first home video game system, and the first arcade video games from Atari, Computer Space and Pong, the latter of which was later transformed into a home console version. Pong's success in arcades and at home prompted numerous firms to create clones of the game, resulting in a market contraction in 1978 owing to oversaturation and a lack of innovation.

By definition a computer is an electronic device used to store and compute data. So, by definition a calculator stores and interprets data/numbers, and that makes it a computer. However, a computer can also use programs, and manipulate stored data to complete those programs.
hope it helps!! :D
