Step by step
Solved in 2 steps
- Create a function, declare and define a static variable in it! Increase the value of the variable and print it out. Call the function in the main() several times! What's happening? ( in C language)In C Declare a variable of type double.Ask the user for a value and place it in the declared variable.Write code to check for and output statement stating whether the variable is zero, positive, ornegative.Write a flowchart and C code for a program that does the following: Within main(), it asks for the user's annual income. Within main(), it calls a function called printIt() and passes the income value to printIt(). You need to include a prototype when creating the function. The printIt() function evaluates the income, and if the number is over 90000, it prints a congratulatory message. If the income is not over 90000, it prints a message of encouragement, like "You WILL make $90,000, if you keep going."
- In C Declare a variable of type double.- Ask the user for a value and place it in the declared variable.- Write code to check for and output statement stating whether the variable is zero, positive, ornegative.- Declare a variable of type character.- Ask the user for a letter and place it in the declared variable.- Write code to check for and output statement stating whether the variable is an upper caseletter, lower case letter, or not a letter (neither of the above).- Write a simple program that is a four function calculator that displays a menu with options a to add, s to subtract, m to multiply, and d to divide two numbers. Ask the user for two float variables in each operation and output the result.C++ Please! Also please don't use functions, arrays, or classes. Just basic c++ please. Password Verifier Write a C++ program to verify that a user’s password meets the following criteria: 1. The password should be at least 6 characters long. 2. The password should contain at least one uppercase and one lowercase letter. 3. The password should have at least one digit. Your program should ask the user for a password and verify that it meets the following criteria. If it doesn’t a message should be displayed telling the user why.(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.
- 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. (11)Q13/ Write a program in c++ that asks the user to input two numbers. If the first number entered is greater than the second number, the program should print the message: "The first number is greater." Otherwise, it should print the message: "The first number is smaller." .By using functions2.) Call backs (True or False): A.) Your program has three functions defined: void a(), void b(), and void c(), followed by your main() function. Your main() function is allowed to call a(), b(), and c(). (True/False) B.) Your program has three functions defined: void a(), void b(), and void c(), followed by your main() function. Your main() function is allowed to call c() but cannot call a() or b(). (True/False)
- C++ programming question: Suppose we have just discovered an alien planet (we will call it Mars), and on this planet one year is divided into 15 months and each month consists of 30 days. i. Write the code for a struct charontime to hold years, months, and days for time on Charon -all ints. ii. Write a function that takes an int parameter that represents the number of Charon days, converts it to years, months, and days on Charon and returns this information in a struct charontime. So for example it will convert 800 days into a struct that represents 1 year, 11 months, and 20 days. iii. Write a function that takes a struct charontime parameter and returns the total number of Charon days represented by the struct. iv. Write a function that takes a filename and an array of struct charontime, opens the file, reads each line as the number of Charon days, converts this to a struct charontime and stores this in the array. (you don't need to create an actual file with number of days in it...…C++ programming question: Suppose we have just discovered an alien planet (we will call it Mars), and on this planet one year is divided into 15 months and each month consists of 30 days. i.

(C++) - One can manipulate logical expressions using the boolean data type. - Boolean data type is declared as a variable initially. - Boolean data type must include decimal spaces and evaluate mathematically to 0 or 1. - One can manipulate algebraic expressions using the boolean data type.
