Concept explainers

Types of Loop

Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.

Loops

Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.

While Loop

Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

why would you choose to utilize a for loop as opposed to a while loop?
In this lab, you use a counter-controlled while loop in a C++ program provided for you. When completed, the program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. The data file contains the necessary variable declarations and some output statements. Instructions Ensure the source code file named Multiply.cpp is open in the code editor. Write a counter-controlled while loop that uses the loop control variable to take on the values 0 through 10. Remember to initialize the loop control variable before the program enters the loop. In the body of the loop, multiply the value of the loop control variable by 2 and by 10. Remember to change the value of the loop control variable in the body of the loop. Execute the program by clicking the Run button. Record the output of this program. **CODE GIVEN** // Multiply.cpp - This program prints the numbers 0 through 10 along // with these values multiplied by 2 and by 10. // Input: None // Output:…

program must include a processing loop that allows multiple sets of data to be processed and the program should be terminated when there is no more data to process Develop a program in python that allows the user to enter a start value of 1 to 4, a stop value of 5 to 12 and a multiplier of 2 to 8. The program must display a multiplication table with results using these values. For example, if the user enters a start value of 3, a stop value of 7 and a multiplier value of 3, the table should be displayed as follows: Multiplication Table 3 x 3 = 9 3 x 4 = 12 3 x 5 = 15 3 x 6 = 18 3 x 7 = 21 Run the program with the following values: Start Stop Multiplier 2 10 4 4 12 6
