Need Help

[iQuarteros]

can you help me with this problem: make a program in C++ that inserts 5 integer and positive values ​​a,b,c,d,e with the keyboard and using only the operations of increase (e.g. a=a+1), decrease (e.g. a =a-1) and comparison with 0 (e.g. a>0, a=0, a<0), determine whether the condition a*b+c>d-e is verified or not. The problem must be solved without using any other variables besides a,b,c,d,e.
