What is for loop in C++<\/strong><\/p>\n

The for loop is a way to iterate a certain block of code a given number of times.<\/p>\n

You may exit a for entirely or may code to exit only one or more iterations by using specified statements \u2013 explained in the sections below.<\/p>\n<\/div>\n

How to write for loop in C++ – the Syntax<\/strong><\/h3>\n

The general syntax of writing a for loop in C++ is:<\/p>\n

for (initialization; condition expression; update expression) {\r\n\r\n\u00a0 \/\/ code block to be executed\r\n\r\n}<\/pre>\n
In the above syntax:<\/strong><\/p>\n\n\n\n\n\n\n
Part<\/strong><\/td>\nDescription<\/strong><\/td>\n<\/tr>\n
initialization<\/strong><\/td>\ne.g. x=1. This is an initialization expression i.e. the loop counter is initialized here. This part executes only once.<\/td>\n<\/tr>\n
Condition expression<\/strong><\/td>\nIn this part of the for loop, the condition is given. If it evaluates as true, the code block inside the curly braces is executed. E.g. x=10.<\/td>\n<\/tr>\n
Update expression<\/strong><\/td>\nAfter executing the statements in the above part, the control comes to this part. There, the value of the variable can be incremented\/decremented. E.g. x++<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Tip: <\/em><\/strong>The for loop is used when you know how many times a block of code should be executed. Otherwise, you may use a while loop<\/a>.<\/em><\/p>\n<\/div>\n
