In decision control statements (if-else and nested if), group of statements are executed when condition is true. If condition is false, then else part statements are executed. There are 3 types of decision making control statements in C language.

Why do we need control statements?

Control statements enable us to specify the flow of program control; ie, the order in which the instructions in a program must be executed. They make it possible to make decisions, to perform tasks repeatedly or to jump from one section of code to another.

What does the if statement do?

The IF statement is a decision-making statement that guides a program to make decisions based on specified criteria. The IF statement executes one set of code if a specified condition is met (TRUE) or another set of code evaluates to FALSE.

What is the decision structure?

A decision structure is a construct in a computer program that allows the program to make a decision and change its behavior based on that decision. The decision is made based on the outcome of a logical test. A logical test is a calculation whose outcome is either true or false.

What is looping statement in VB?

A loop statement allows us to execute a statement or group of statements multiple times and following is the general form of a loop statement in most of the programming languages − VB.Net provides following types of loops to handle looping requirements.

What is else if statement?

Alternatively referred to as elsif, else if is a conditional statement performed after an if statement that, if true, performs a function. … The above example could also be extended by adding as many elsif or else if statements as the program needed. Note. Not all programming languages are the same.

Which statements provide a way to repeat commands?

Answer: Yes, loop statement provide a way to repeat certain commands/ instruction. For given index variable ,control enters the loop and execute sequence of instruction. While loop executes the block of statements if given condition met.

What is a looping statement?

A loop statement is a series of steps or sequence of statements executed repeatedly zero or more times satisfying the given condition is satisfied. Loop statements in programming languages, such as assembly languages or PERL make use of LABEL’s to execute the statement repeatedly.

When we check for certain conditions to execute further then it called as decision statements. … When we have to execute particular set of instructions multiple times or known number of times (iterations), then we use FOR loops or DO/WHILE loops.

Which statement is executed first in a decision making statement?

The above program uses if conditional statements. Here, the first if statement checks whether the given condition i.e., variable x is greater than 95 or not and if it finds the condition is true, then the conditional body is entered to execute the given statements.

What do you mean by decision making in C which are the statements in C that provide the facilities of decision making and branching?

In C programming it support sequential program statements which execute one statement immediately after another. Here the flow is sequential it never change the flow of control from the next line. The compiler executes the program sequentially in the order which they appear.
