- In C++ (Algebra: solve 2 × 2 linear equations) You can use Cramer’s rule to solve the following 2 × 2 system of linear equation: ax + by = ecx + dy = fx = (ed - bf) / (ad - bc)y = (af - ec) / (ad - bc) Write a program that prompts the user to enter a, b, c, d, e and f and displays the result. If ad - bc is 0, report that “The equation has no solution”. Sample Run 1 Enter a, b, c, d, e, f: 9.0 4.0 3.0 -5.0 -6.0 -21.0 x is -2 and y is 3 Sample Run 2 Enter a, b, c, d, e, f: 1.0 2.0 2.0 4.0 4.0 5.0 The equation has no solutionarrow_forwardIn C++ Ask a user to enter any real number and determine the square of that real number.arrow_forwardAnswerarrow_forward
- (Civil eng.) Write an assignment statement to calculate the linear expansion in a steel beam as a function of temperature increase. The formula for linear expansion, l, is as follows: l=l0(1+(TfT0)) l0isthelengthofthebeamattemperatureT0.isthecoefficientoflinearexpansion.Tfisthefinaltemperatureofthebeam.arrow_forward(Civil eng.) Write a C++ program to calculate and display the maximum bending moment, M, of a beam that’s supported on both ends (see Figure 3.8). The formula is M=XW(LX)/L, where X is the distance from the end of the beam that a weight, W, is placed, and L is the beam’s length. You program should produce this display: The maximum bending moment is xxxx.xxxx The xxxx.xxxx denotes placing the calculated value in a field wide enough for four places to the right and left of the decimal point. For your program, assign the values1.2,1.3,and11.2toX,W,andL.arrow_forward(Numerical) a. Write a C++ program that accepts an integer argument and determines whether the passed integer is even or odd. (Hint: Use the % operator.) b. Enter, compile, and run the program written for Exercise 8a.arrow_forward
- Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls.

C# chooses a unifying type for the result you must choose a unifying type for the result you must provide a cast you receive an error messagearrow_forwardC++arrow_forward
- in c++ void check_palindrome() - to check whether the given number by user is palindrome or not. write a program using above function to check whether the number is palindrome or not. please add comments also.arrow_forwardDetect Even/Odd Write a function with no parameters, even_or_odd() in Python Specifications: read an integer from standard input return 0 if the integer is even, 1 if the integer is odd do not use a conditional ("if") statement, just use modular arithmetic (such as // or %) do not print the result, return it HINT: What is the remainder when you divide an even number by 2? What is the remainder when you divide an odd number by 2? REMINDER: DO NOT use prompts in your input statements for this problem. For example: Test Input Result ans = even_or_odd() print(ans) 5 1 ans = even_or_odd() print(ans) -14 0 ans = even_or_odd() print(ans) 0 0 ans = even_or_odd() print(ans) 99 1arrow_forwardUse C++ Codingarrow_forward
