How do i increment statement or decrement statement in C? [closed]

by 

for(i=0; i < numberOfProducts; ++i)

and

for(i=0; i < numberOfProducts; i++)

are both equivalent as you are not reading the result of the operation (like in a = i++ vs a = ++i). The latter form is more common.

If you have different results, you probably have issues in the way you are testing your program.
