Create a file called numinput. txt and put some integers in the file. save the file in the same directory as your source code in your project. create an interactive program that reads an int from the file called numinput. txt, performs a calculation, and stores the result in a different file called resout. txt.
1. ask the user for a double.
2. open a file called numinput. txt, and use fscanf to read an int from this file.
3. multiply the double entered by the user by the int from the file, and store the result in a double.
4. open a file called resout. txt.
5. use fprintf to write the result of the multiplication to the file resout. txt.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
