Basically your program has a sound logic, and it actually works after making two minor corrections.
Namely, the continue statements should be enclosed in braces {} with the previous statement, such as:

if (operand1 < = 0) { printf("the entry was incorrect for operand1"); continue; }
and later
if (operand2 < = 0) { printf("the entry was incorrect"); continue; }
so that the continue statement does not get executed even if the operands are greater than zero.

If you have time for more exercise, I would suggest you check the operators entered by the user, so that if the user enters an illegal operator, it will give a message.

Keep up the good work.
