Hướng dẫn how can i print even and odd numbers in php? - làm cách nào để in số chẵn và lẻ trong php?

Ngày 27 tháng 7 năm 2016

Để in các số chẵn và số lẻ, chúng ta có thể sử dụng các loại phương thức khác nhau. Giá trị của nó tăng thêm 2 cho các số in chẵn.
Method:1
Even numbers between 1 to 100
In first method we use ‘for’ loops to print even numbers between 1 to 100. Here loop starts from number 2 and after every count its value increment by 2 for print even numbers.

<?php echo "Even numbers between 1 to 100 :- "; for ($j=2; $j<=100; $j+=2){ echo $j.", "; } ?>

Các số lẻ từ 1 đến 100 trong phương pháp đầu tiên, chúng tôi sử dụng ‘cho các vòng lặp để in các số lẻ trong khoảng từ 1 đến 100. Ở đây vòng lặp bắt đầu từ số 1 và sau mỗi lần tính giá trị của nó tăng 2 cho các số lẻ.
In first method we use ‘for’ loops to print odd numbers between 1 to 100. Here loop starts from number 1 and after every count its value increment by 2 for print odd numbers.

<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?>

Phương pháp: 2Ven Số từ 1 đến 100 trong phương pháp thứ hai, chúng tôi sử dụng 'cho' vòng lặp và 'if' để in số chẵn từ 1 đến 100. Ở đây vòng lặp bắt đầu từ số 1 và sau mỗi lần tính giá trị của nó tăng 1, khi 'nếu' 'Điều kiện sẽ đúng, nó in thậm chí số.
Even numbers between 1 to 100
In second method we use ‘for’ loops and ‘if’ condition to print even numbers between 1 to 100. Here loop starts from number 1 and after every count its value increment by 1, when ‘if’ condition will be true, it print even numbers.

<?php echo "Even numbers between 1 to 100 :- "; for ($j=1; $j<=100; $j++){ if( $j%2==0){ echo $j.", "; } } ?>

Các số lẻ trong khoảng từ 1 đến 100 trong phương thức thứ hai, chúng tôi sử dụng 'cho' vòng lặp và 'if' để in các số lẻ trong khoảng từ 1 đến 100. Ở đây vòng lặp bắt đầu từ số 1 và sau mỗi lần tính giá trị của nó tăng 1, khi điều kiện 'if' Sẽ đúng, nó in số lẻ.
In second method we use ‘for’ loops and ‘if’ condition to print odd numbers between 1 to 100. Here loop starts from number 1 and after every count its value increment by 1, when ‘if’ condition will be true, it print odd numbers.

<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=100; $j++){ if( $j%2!=0){ echo $j.", "; } } ?>

<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?> 3<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?> 9 <?php echo "Even numbers between 1 to 100 :- "; for ($j=1; $j<=100; $j++){ if( $j%2==0){ echo $j.", "; } } ?> 9<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=100; $j++){ if( $j%2!=0){ echo $j.", "; } } ?> 0

Sử dụng thao tác bit: Trong phương pháp này, chúng ta sẽ tìm thấy bit khôn ngoan và số lượng với 1. Nếu bit khôn ngoan và là 1, thì số này là số lẻ, khác thậm chí.

Dưới đây là việc thực hiện ý tưởng trên.{IDE} first, before moving on to the solution.

function <?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?> 0<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?> 1<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=100; $j++){ if( $j%2!=0){ echo $j.", "; } } ?> 8

1. <?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?> 3<?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?> 04 <?php echo "Odd numbers between 1 to 100 :- "; for ($j=1; $j<=99; $j+=2){ echo $j.", "; } ?> 05: This is the simplest method of checking for even and odd and in this method, we simply check whether the number is divisible by 2 or not using the modulo ‘%’ operator.

2. Phương pháp đệ quy: Trong cách tiếp cận đệ quy, chúng ta giảm số xuống 2 trong mỗi cuộc gọi đệ quy. Nếu số cuối cùng là 0 thì nó thậm chí là 1, kết quả sẽ là lẻ.: In the recursive approach, we reduce the number by 2 in each recursive call. If the final number is 0 then its even or else it is 1, the result will be odd.
   Below is the implementation of above approach:
