What do you mean by block statement?

A block statement is a sequence of zero or more statements enclosed in braces. A block statement is generally used to group together several statements, so they can be used in a situation that requires you to use a single statement. In some situations, you can use only one statement.

What is block structure in C?

In computer programming language: ALGOL. ALGOL introduced block structure, in which a program is composed of blocks that might contain both data and instructions and have the same structure as an entire program. Block structure became a powerful tool for building large programs out of small components.

What is the difference between a statement and a block in C?

Your definitions are correct. If is actually both typically. The if statement itself is just that, a control flow statement. If the statement is evaluated to true it executes the statement, or block after it. In other words, the block after an if is not required if you just wanted to execute a single line of code.

What is a block of code in C ++?

A block is a logically connected group of program statements that is treated as a unit. In C++, a code block is created by placing a sequence of statements between opening and closing curly braces. They are a logical unit: One of the statements cannot execute without the other also executing.

What is the main purpose of using blocks?

A block creates a const copy of any local variable that is referenced inside of its scope. Before blocks, whenever you wanted to call some code and have it call you back later, you would typically use delegates or NSNotificationCenter.

What does block of statements always start with?

A code block (body of a function, loop, etc.) starts with indentation and ends with the first unindented line. The amount of indentation is up to you, but it must be consistent throughout that block. Generally, four whitespaces are used for indentation and are preferred over tabs.

What is statements in C program?

A statement is a command given to the computer that instructs the computer to take a specific action, such as display to the screen, or collect input. A computer program is made up of a series of statements.

What is statement in C with example?

Most statements in a typical C program are simple statements of this form. Other examples of simple statements are the jump statements return, break, continue, and goto. A return statement specifies the return value for a function (if there is one), and when executed it causes the function to exit immediately.

How many villages are in a block?

The Panchayat Samiti, also called the Block Samiti, is a council formed to represent a block of approximately ten villages.

How many statements a block can hold?

Blocks have two functions: to group statements so that they can be treated as one statement; and to define scopes for names to distinguish them from the same name used elsewhere.

What must the used when a block of statements to be repeated for many number of times?

While loops. As mentioned earlier, while loops are used when a block of statements have to be repeated, but the number of repetitions is not a fixed amount. This means that a while loop might repeat two times when a program is run and repeat a different number of times the next time that same program is run.
