- 3) Write a general program that computes the values e" by using the following equation. Calculate the output when x=3. The equation must have 15 terms with x. e* =1++ 2x (2x) , (2x) 1! 2! +.. 3! Do not write the program by simply adding the terms in the equation. You are allowed to use "math.h" functions.b) Wnite a C++ program, which uses a 'switch' statement to respond to different inputs from a user. The user may enter either 1, 2 or 3. If the input is 1, the program asks the user to input two numbers, which correspond to the length and width of a rectangle. The program then calculates the area of the rectangle and outputs the result by displaying the message "This is a rectangle. Its area is: Vvalue. If the input is 2, the program prints out the message "This is a triangle". If the input is 3, the program prints out the message "This is a circle"Q1/ Write a C++ program to calculate the volume of a sphere V, where the volume can be found using the following equation: V = (R³) with It is the constant ratio (π =3.14) and R is the radius. The program should interrupt the user to input the value of R then display the output formatted as below: The volume of a sphere with a radius of "R" is "V"

- حسام ٢٠٢١ Using functions, write a full C++ program that reads four integer numbers entered by the user two at a time (num1 & num2, and then num3 & num4). Your program should find and display the sum of products (SoP) and the product of sums (PoS) of these numbers to the user. NOTEs: • Sum of Products (SoP): get the product of the first two numbers, get the product of the second two numbers, and then add these products together. • Product of Sums (PoS): get the sum of the first two numbers, get the sum of the second two numbers, and then multiply these sums together. Example: if the four numbers entered are 2&3, and then 4&5… The SoP is (2*3)+(4*5)=26, and the PoS is (2+3)*(4+5)=45 Use the following prototypes: int sumOprod(int a, int b, int c, int d); int prodOsum(int a, int b,int c, int d); #include using namespace std; int sumOprod(int a, int b, int c, int d); int prodOsum(int a, int b,int c, int d); int main() {Write C++ statement(s) that accomplish the following: Declare variables x and y.

Declares int variables a and b. . Updates the value of an int variable y by adding 5 to it. i. Copies the content of an int variable y into an int variable z. iv. Declares int variables to store four integers. v. Outputs the content of a variable x and an expression 2 * x + 5 - y, where x and y are double variables. c) Suppose x, y and total are int variables and z is a double variable. What value is assigned to each variable after each statement executes? Assume x = 6, y = 10, and z = 28.2.
- . In the sport of diving, seven judges award a score between 0 and 10, where each score may be a floating-point value. The highest and lowest scores are thrown out and the remaining scores are added together. The sum is then multiplied by the degree of difficulty for that dive. The degree of difficulty ranges from 1.2 to 3.8 points. The total is then multiplied by 0.6 to determine the diver’s score. Write a c++ computer program that inputs a degree of difficulty and seven judges’ scores, and outputs the overall score for that dive. The program should ensure that all inputs are within the allowable data ranges.c) Write a program for the following problem by using for statement: Ahmad saves RM1000 in his account in a bank which returns 5% of annual interest. Assuming that all interests is left deposited in his account, calculate and print the amount of money in his account at the end of each year for 10 years by using for loop. Use the following formula to determine these amounts: a = p(1+ r)" Where; a = the amount of deposit at the end of nth year p = original amount saved r = annual interest rate n = number of year(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.
