User Defined DataType

The data type is a format to store data that contains a particular range or type of value. It specifies which type of value a variable should have. In other words, a data type describes the type of data that variables can store. When a program stores data in the variables, then every variable needs to be assigned value that falls within the range of its data type. The following are some of the data types:

C PROGRAMMING ONLY, Having trouble with this step as well, thank you so much for the help! NO IOSTREAM.H OR CACIO.H PLEASE I CANT USE THOSE HEADERS. Modify the given Script to meet the following conditions: Create a C script that will: 1) Read a text file “Data.txt”. The numbers in the first column of Data.txt are a1’s, thesecond column are a2’s, the third column are y(0)s and the fourth column are y’(0)s. 2) Use these numbers to find the Zero-Input Responses. (So, the user will not type inthose numbers. Your program should read those values from the Data.txt file automatically.Then, your program should compute the roots and required coefficients.) 3) Save the result (Coefficients) on “Result.txt” Here is the format for Result.txt;1) The first column indicates whether the system has nonrepeating real roots, repeatingreal roots, or complex conjugate roots. Use 1 for nonrepeating real roots, 2 for repeatingreal roots, and 3 for complex conjugate roots.2) The second column should be used…
