In this lab you will use a single dimension array in which to store the characters you get from the input buffer. The lab will also use a method of parameter passing to the function called “pass by reference”. This lab will determine if the characters in the input buffer are integer or floating point and signed or unsigned. The program will convert the characters to a double type numeric value. In main, read a string of characters, one string at a time until the file is empty. Each line of the file will contain one number in the form of a character string. The program will not check for input errors so be sure that you do not type any errors in the file. Store the string in a single dimension array of type char. When the file is empty terminate the loop, and pause the program using the getch() function. Print a message before you pause the program such as “press any key to terminate the program”. Write a function to convert the characters (in the array) to a numeric value and store the result in a variable of type double. While converting from characters to a number, you should check for a minus sign. There cannot be a blank between a minus sign and a digit. There can be a decimal point after a minus sign. A number ends with a blank, a non-digit character, or the end of the buffer (array). For this program, all numbers will end with the “end of line” character which should be converted to the NULL character as the result of reading the string into the array. Pass to the function the array with the string and use “pass by reference” for all other arguments. The following arguments will be assigned a value in the function: number converted from character string, type of number (1 for integer, 2 for floating point), number of digits before the decimal point, number of digits after the decimal point. Each time you read a string from the disk file print the string to the screen before you call the function to convert the string to a numeric value. Output should be displayed in the following form. You must be able to display at least a total of 16 digits plus a minus sign if applicable. The number may have no digits before the decimal point, no digits after the decimal point or digits before and after the decimal point. For example if the file contain the following strings, you would output the following: input was: 6789 6789 is an integer number, it contains 4 digits input was: -5436789 -5436789 is an integer number, it contains 7 digits input was 89563.25 89563.25 is a floating point number, it contains 7 total digits, 5 digits before decimal point, 2 digits after decimal point input was .4444433333 .4444433333 is a floating point number, it contains 10 total digits, 0 digits before decimal point, 10 digits after decimal point input was: .000040376 .000040376 is a floating point number, it contains 9 total digits, 0 digits before decimal point, 9 digits after decimal point input was: 854623585. 85461423585. is a floating point number, it contains 11 total digits, 11 digits before decimal point, 0 digits after decimal point Name the file you create LAB3.
