Repetition structure.<\/p>\n<p>A repetition structure, also known as a loop, is a programming construct that allows a block of code to be executed repeatedly until a specific condition is met. Loops are used to perform repetitive tasks, such as printing a list of numbers, calculating a sum, or searching for a value in a list.<\/p>\n<p>There are three main types of loops: for loops, while loops, and do-while loops.<\/p>\n<ul>\n<li>A for loop is a repetition structure that repeats a block of code a <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> specified number of times. The syntax for a for loop is as follows:<\/li>\n<\/ul>\n<p><code>for (initialization; condition; increment) {<br \/>\n  \/\/ code to be executed repeatedly<br \/>\n}<\/code><\/p>\n<p>The initialization statement is executed once, before the loop begins. The condition statement is evaluated before each iteration of the loop. If the condition is true, the code inside the loop is executed. The increment statement is executed after each iteration of the loop.<\/p>\n<ul>\n<li>A while loop is a repetition structure that repeats a block of code as long as a specified condition is true. The syntax for a while loop is as follows:<\/li>\n<\/ul>\n<p><code>while (condition) {<br \/>\n  \/\/ code to be executed repeatedly<br \/>\n}<\/code><\/p>\n<p>The condition statement is evaluated before each iteration of the loop. If the condition is true, the code inside the loop is executed. The loop will continue to iterate as long as the condition is true.<\/p>\n<ul>\n<li>A do-while loop is a repetition structure that is similar to a while loop, except that the condition is evaluated at the end of the loop instead of at the beginning. This means that the code inside the loop will always be executed at least once, even if the condition is false. The syntax for a do-while loop is as follows:<\/li>\n<\/ul>\n<p><code>do {<br \/>\n  \/\/ code to be executed repeatedly<br \/>\n} while (condition);<\/code><\/p>\n<p>The code inside the loop is executed, and then the condition is evaluated. If the condition is true, the loop will continue to iterate. If the condition is false, the loop will terminate.<\/p>\n<p>Loops are a powerful tool that can be used to simplify code and make it more efficient. They are used in a variety of programming languages, including Python, Java, C++, and C.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Subscribe on
