Ushani Harshila , ‚Ė™Ôłéif the input file 'dataset1.txt' is existing in the correct folder (same as where code file is located), the program will create no error. i can not say if your calculation is correct, this is up to you to check. ‚Ė™Ôłéif you run the code multiple times, the output will be appended to the output file 'out.txt'. this means that the file content is increasing (repeated) with each code ecexecution this is the result: x: 10.0000 y: 3.0000 z: -0.2930 x: 7.0000 y: 6.0000 z: 0.4144 x: 9.0000 y: 4.0000 z: -0.1110
