In this program, structures n1 and n2 are passed as an argument of function add().
This function computes the sum and returns the structure variable temp to the main()function.
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
