## Beecrowd 1073 Even Square Problems Solution in C++, C, and Python

## Even Square

Read an integer **N**. Print the square of each one of the even values from 1 to **N **including **N **if it is the case.

## Input

The input contains an integer **N **(5 < **N **< 2000).

## Output

Print the square of each one of the even values from 1 to **N**, as the given example.

Be carefull! Some language automaticly print 1e+006 instead 1000000. Please configure your program to print the correct format setting the output precision.

Input Sample | Output Sample |

6 | 2^2 = 4 4^2 = 16 6^2 = 36 |

First, letâ€™s take a closer look at the problem itself. The URI BeeCrowd Bee 1073 Even Square problem asks you to find all the even numbers between 1 and a given number, and then print each number and its square on a separate line. This is a fairly simple problem, but it does require some basic coding skills and knowledge of loops and conditionals.

To solve this problem in C, C++, or Python, youâ€™ll need to use a loop to iterate over all the even numbers between 1 and the given number. Then, for each even number, youâ€™ll need to calculate its square and print the result to the console. Weâ€™ll provide detailed code examples in each language below.

## C Solution

```
#include <stdio.h>
int main() {
int i,n,s=1;
scanf("%d",&n);
for(i=1;i<=n;i++){
if(i%2==0){
s=i*i;
printf("%d^2 = %d\n",i,s);
}
}
return 0;
}
``````
```

In this C solution, we use a for loop to iterate over all the even numbers between 2 and the given number. We start at 2 instead of 1 because we know that 1 is not an even number. We increment the loop variable i by 2 at each iteration, which ensures that we only visit even numbers. Inside the loop, we print out the square of the current number using the `%d`

format specifier for integers.

## C++ Solution

#include <iostream> using namespace std; int main() { int n; cin >> n; for(int i = 2; i <= n; i += 2) { cout << i << "^2 = " << i*i << endl; } return 0; }

In this C++ solution, we use a similar approach to the C solution, but we use `cout`

and `cin`

instead of `printf`

and `scanf`

. We also use the `namespace`

keyword to avoid having to prefix `cout`

and `cin`

with `std::`

every time.

## Python Solution

```
n = int(input())
for i in range(2, n+1, 2):
print(f'{i}^2 = {i*i}')
```

In this Python solution, we use a `for`

loop and the `range`

function to iterate over all the even numbers between 2 and the given number. We use an f-string to print out the square of the current number.
