- 1) Write a program in C++ that take three scores from user and calculate the average using do-while loop. It repeats as many times as the user wishes. The program only terminates when a user press N and Y to continue again any other character should display invalid character.-Program C 3. Negative Allergy by CodeChum Admin Whole numbers are great, but I think we should also pay attention to decimal numbers, too. So, how about we make a program that involves a lot of decimals? Instructions: Continuously ask for floating point values (decimal numbers) using the do…while() loop, sum them all up, and store the total into one variable. The loop shall only terminate for the following reasons: A negative decimal number is inputted (but still included in the total sum) The total sum reaches 100.0 or more Input 1. A series of float numbers Output The first multiple lines containing message prompts for float numbers. The last line contains the sum with 2 decimal places. Enter·a·number:·1.1 Enter·a·number:·1.2 Enter·a·number:·1.3 Enter·a·number:·1.4 Enter·a·number:·-1.0 Sum·=·4.00IN C++ PROGRAMMING LANGUAGE!!!

- Numerical analysis) Given a number, n, and an approximation for its square root, a closer approximation of the actual square root can be found by using this formula: newapproximation=(n/previousapproximation)+previousapproximation2 Using this information, write a C++ program that prompts the user for a number and an initial guess at its square root. Using this input data, your program should calculate an approximation of the square root that’s accurate to 0.00001. (Hint: Stop the loop when the difference between the two approximations is less than 0.00001.)(cin within a loop) Write and run a C++ program that accepts 10 values of gallons, one at a time, and converts each value entered to its liter equivalent before the next value is requested. Use a for loop in your program. Use the fact that 1gallon=3.785liters.(Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.
- CODE USING C++ 1. Squares by CodeChum Admin Looping random numbers and manipulating those values are fun, too! Why don't we try one that returns the square of an inputted number repeatedly until the user inputs 0? Let's do this! Instructions: Using a do...while() loop, continuously scan for random integers that will be inputted by the user and print out its square, separated in each line. Once the inputted value is 0, it will still print out its square value but should then terminate the loop afterwards. Use this concept in making your loop condition. Input Multiple lines containing an integer. 2 6 0 Output Multiple lines containing an integer. 4 36 0Write c++ code(using nested while loop only)Write a C program executes the multiplication of two numbers entered by the user using only the addition operation. if the user enters 3 and 4, the program computes the multiplication of these numbers by adding the number 4 three times (i.e., 4 * 4 = 4 + 4 + 4 + 4). • Write the C code using loops and write the code and replace the ‘for’ loop with ‘goto’ statements.
- Rewrite the following code using while loop statement instead of for loop statement in C++. #include <iostream> using namespace std; int main() { int count,total(0),num; for(count=1;count <= 8;count++) { cout << "\nEnter a number: "; cin >> num; total = total + num; cout << "The total is now " << total; } return 0; }-Program C 3. There was a Three by CodeChum Admin I'm bored with just basic counting. How about we do some complex things this time? But I don't want to be associated with any number that's not divisible by 3. Think you can handle this? Instructions: Print out all numbers from 1 to 100 that is divisible by 3, each in separate lines, using a for() loop. Output Multiple lines containing an integer that is divisible by 3. 3 6 9 12 15 18 21 . . .PLEASE SOLVE THIS IN C++ CODE ONLY! PLEASE READ AND DO THE PROGRAM WITH ACCORDING TO THE CONDITIONS GIVEN. PLEASE ALSO WRITE THE USE OR FUNCTIONS OF EACH CODE USED BY INSERTING ITS USE EVERY LINE USING "//" A palindrome is a string that reads the same from front to back as it does from back to front, e.g., "racecar", "radar", "21012". Write a program that will identify whether a given line of input is a palindrome or not. Your program must also be able to determine the following sample inputs as palindromes, aside from identifying one-word inputs: Able was I 'ere I saw Elba. Madam, I'm Adam. A man, a plan, a canal, Panama. These samples require that your program must ignore spaces and punctuations, and consider uppercase and lowercase letters to be the same. Include necessary functions in your program to process the input. You can also use existing functions from the string library.
