Flow control statements that modify the execution flow are divided into several functional groups: In Python we usually have two loops/repeating instructions: Jump instructions are instructions through which we can transfer control anywhere in the program. These instructions transfer control of the program by ignoring instructions that do not have specified conditions. These statements are: if-elif-else: The if-elif-else statement is used to conditionally execute a statement or block of instructions. while loop: In Python, while loops are used to execute a block of instructions repeatedly until a specific condition is met. Then the expression is checked again and, if it is still true, the body is executed again. This continues until the expression becomes incorrect. The selection statement allows a program to test multiple conditions and execute statements based on the true condition. Easy if: when statements are control flow statements that help us execute a particular code, but only when a certain condition is met or met. A simple if has only one condition to check. Instruction labels can only be displayed in procedures. A module-level statement in a script that is not included in a procedure cannot be labeled. Because a particular label is known only in the procedure in which it is defined, a branch statement that can pass control to a labeled statement can only be displayed in the same procedure as the labeled statement.
The instructions that can transfer control to a labeled statement are GoTo, GoSub, On. GoTo, On. GoSub, yes. Goto. If not, and continue. If an error occurs, it is governed by an On error. The GoTo label statement, In Case of Error and the labeled statement must be in the same procedure. If there is another if-else instruction block in an outer block of if-else, it is called nested if-else.
Iterative statements are also called repetitive statements or loop instructions. A loop statement is used when the program requires the execution of a statement (or the repeated execution of a series of instructions) until a condition for the end of the loop is met. Some other statements also do not produce executable code. These include Option Base, Option Compare, Option Declare, and Option Public; the Type statement; and Deftype statements. In general, control instructions help control the program. But do we mean by flow of control? In Python, selection statements are also called decision control instructions or branch instructions. If a continuous statement is found, it ignores the rest of the statements to be executed in the current loop and the control returns to the next iteration. This means that statements found after the Assert statement will not be executed for the current iteration. The control flow of a Python program is governed by conditional statements, loops, and function calls. Continue can only be used in a loop control statement.
For loop: A FOR loop is used to iterate through a sequence that is either a list, a tuple, a dictionary, or a set. We can execute a series of instructions once for each item in a list, tuple, or dictionary. Nested if: Nested if the statements are an if statement in another if statement. 3. What is true about a break? a) Pause stops the execution of the entire program b) Pause stops execution and forces control out of the loop c) Pause forces control out of the loop and begins the execution of the next iteration d) Pause stops running the loop for a specified period of time Show response The remaining sections of this chapter explain these statements in the order listed above. These control instructions help implement decision-making in a program. A conditional statement selects the block of statements to execute based on the specified condition. The result of the program depends on the condition. These indicate that a group of auxiliary declarations is repeated several times or during or until a certain condition is met. BREAK statements are used in loops to stop execution if they are found.
The control flow of a program is the order in which the program code is executed. This code displays a real block and a fake block. If the condition is true, the control is passed to the written instructions under the if block. If the condition is false, it is passed to the statements under the else block. The control flow is the order in which statements are executed. For example, the flow of the program is usually top-down (sequential stream), but what if we want a particular block of code to run only if it meets a certain condition or if we want to run a block of code a certain number of times? These instructions ensure the proper functioning and intended functioning of a program. There are no built-in limits to the level or manner in which these statements are nested. For example, a Do statement can contain another Do statement that contains a third Do statement, or a Do statement can contain a For statement that contains another Do statement. Sequential statements are a group of instructions whose execution process takes place in a sequence.
The problem with sequential statements is that if the logic of one of the lines is interrupted, the complete execution of the source code is interrupted. The execution flow can also be changed at run time if an error occurs. Either execution stops or an On Error statement in the script specifies how to respond to the error in one of the following ways: These indicate how to continue execution at another point in the script, possibly under certain conditions. 9. Where does the break statement cause an exit from? a) Only from the innermost loop b) Terminates a program c) Only from the innermost switch d) From the innermost loops or switches Show response If the specified condition is true, the result is 1; If it turns out to be false, the result is 0. If a logical value exists, the code runs. Otherwise, it will not be the case. 6.
What type of data is valid for variable « a » to print « Hello World »? If there is a loop variable that behaves like a counter and increments for the durations specified for the while loop, the loop variable must be initialized before it is used in the while loop state.
