In PostgreSQL, the FOR loop is used for iterating over a range of values or a result set. The below figure shows the working flow of the FOR loop in PostgreSQL: Syntax It works similarly to traditional programm
In computer science a for loop is a programming language statement which allows code to be repeatedly executed. A for loop is classified as an iteration statement. Unlike many other kinds of loops, such as the while loop, the for loop is often distinguished by an explicit loop counter or...
As mentioned before, there are generally three types of loops used in C++: For loop: It allows users to execute a block of code a specific number of times. While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to ex...
