Task 1

Write a program in C++ that reads data from a file. Create dynamic memory according to the data. Now your task is to perform the following task.

  1. Row wise Sum
  2. Column wise Sum
  • Diagonal wise Sum

 

Example

 

data.txt

4

5 1.6 10.2 33.7 99 20.5

3 44 50 96.1

2 8 9

4 74 50 99 19.1

 

Output:

Sum row wise: 165, 191, 17, 242.1

Sum col wise: 127.6, 120.1, 228.8, 118.1, 20.5

Sum diagonal wise: Not Possible

 

Note: You are restricted to use pointers and your function should be generic. Avoid memory wastage, memory leakage, dangling pointer. Use regrow or shrink concepts if required.
