- In C++, what is a const char*? And when using const char* would this be well suited or just using string&? As well as why do I get an error when I try having the username has const char, but I do not get an error when making const char username into a const char* username? What is the reason for this error I am getting?In C++ and using command line arguments, how do you check if an argument is a double or integer?a) What is the risk of using strcpy() in C given the code below? void f1(char *str2) { int y; char str1[10]; strcpy(str1, str2);
- a. Write a c program that asks a user for an integer. Declare a variable num1. Let num1 = ++x; Display the values of x, and num1 b. Write a c program that asks a user for an integer. Declare a variable num2. Let num2 = x++; Display the values of x, and num2.Find the C program language Deal or No Deal?by CodeChum Admin When I was a kid, I used to watch this TV game show, Deal or No Deal? In the game, there are different brief cases, each labeled with a number. Inside each brief case is an amount in Pesos and the goal is to guess which briefcase contains the smallest amount. In this program, instead of just finding the smallest amount, your task is to ask the user for an integer input and print the values in the array smaller than the inputted integer. Instructions: In the code editor, you are provided with an array with 100 elements.Your task is to ask the user for an integer input and then print all the elements in the array whose value is lesser than the inputted integer.Input 1. Inputted integer Output Enter value: 6132450351503022244This is a C++ programming question The code should be in C++ language When you borrow money to buy a house, a car, or for some other purposes, then you typically repay it by making periodic payments. Suppose that the loan amount is L, r is the interest rate per year, m is the number of payments in a year, and the loan is for t years. Suppose that i = (r / m) and r is in decimal. Then the periodic payment is: You can also calculate the unpaid loan balance after making certain payments. For example, the unpaid balance after making k payments is: where R is the periodic payment. (Note that if the payments are monthly, then m = 12.) Write a program that prompts the user to input the values of L, r, m, t, and k. The program then outputs the appropriate values. Your program must contain at least two functions, with appropriate parameters, to calculate the periodic payments and the unpaid balance after certain payments. Make the program menu driven and use a loop so that the user can repeat…
- I need help understanding each line of code. Can you please explain each line of code so I can fully understand what is going on step by step? I have experience in c++ so maybe you can also point out some differences between this code and c++ code. Thank you! #include <stdio.h> int main(void) { char *stringPtr = "Hello world.\n"; while (*stringPtr != '\0') { printf("%p: ", stringPtr); printf("0x%02x\n", *stringPtr); stringPtr++; } printf("%p: ", stringPtr); printf("0x%02x\n", *stringPtr); return 0; }a. Write a c program that asks a user for an integer. Declare a variable num3. Let num3 = --x; Display the values of x, and num3.b. Write a c program that asks a user for an integer. Declare a variable num4. Let num4 = x--; Display the values of x, and num4.In this chapter, you learned that although a double and a decimal both hold floating-point numbers, a double can hold a larger value. Write a C# program named DoubleDecimalTest that declares and displays two variables-a double and a decimal. Experiment by assigning the same constant value to each variable so that the assignment to the double is legal but the assignment to the decimal is not. In other words, when you leave the decimal assignment statement in the program, an error message should be generated that indicates the value is outside the range of the type decimal, but when you comment out the decimal assignment and its output statement, the program should compile correctly.
- C++ programming 2. What is the output of the following program (when embedded in a complete program)? void Fun( int& x, int y, int& z); int main( ) { int a, b, c; a = 10; b = 20; c = 30; Fun(a, b, c); cout << a << " " << b << " " << c << endl; return 0; } void Fun( int& x, int y, int& z) { cout << x << " " << y << " " << z << endl; x = 1; y = 2; z = 3; }Martin wants to create a program in c++ that requires the user to input 10 integers then print the total number of even integers, highest even integer, lowest even integer, total number of odd integers, highest odd integer, and lowest odd integer. If, however, the user inputs zero (0), the program will display “You have not yet entered 10 integers.”.Please written by computer source 1, 2 C++ Programming. Please answer ASAP. Thank you very much. Question 1: Write a C++ program that reads two marks (a mark for mathematic course and another mark for physics course) and the weighting of the mark of mathematics compared to that of physics. The program then displays the weighted average with two obligatory decimals. Below is the example of how the program should look like. Enter average in math 80.25 Enter the average in physics 100 Enter the weight assigned to mathematics 0.4 The weighted average is then 92.10% 2) Write a C++ program that asks for the different prices for a bus ticket (adult, child, senior). Then, the program asks for the number of adults, elders, and children in the group. The program then displays the total ordered without taxes.
