Question

For this program, I am NOT allowed to use an array orvector. These are the instructions for the program: You are given three data files that contain integer values.Each file has a different set of numbers. Each file has its set ofnumbers in sorted order (low to high). Write a program that willread the data for the three files and output one (1) file ofnumbers in sorted order. Example: file A, B, C FileA:         1   15   16   23   51 FileB:         0   91   101   122   130 FileC:         23   33   34   63   200 OutputFile:   0   1   15   16   23   32   33   34   51   63   91   101   122   130   200 Again, I cannot use an array or vector.
