3. Given two arrays, we can append one array to the end of the other. For example x2 result 0.7 1.6 3.2 1.3 2.3 4.2 0.7 1.6 3.2 1.3 2.3 4.2 Write a program, appendarrays.c, which reads two arrays x1 and x2 from the files array1.txt and array2.txt, appends x2 to the end ofx1, and then writes the result to the file appendarraysout.txt In more detail main carries out the following steps: opens the three files array1.txt, array2.txt, and appendarraysout.txt . reads the first array x1 from the file array1.txt . reads the second array x2 from the file array2.txt calls the function append, which appends x2 to the end of x1 resulting in a new array y writes the size of y followed by the values of y to the file appendarraysout.txt
