Question

3PQ+2QR-2PR/3Q IN C++ expression

Answer 1

Remember that in c/c++ there is no assumed multiplication. For example:

int A = 5;
int B = 2;
int C = AB;

Would generate an error that AB is undefined. That is because AB is a new variable, not the multiplication of A and B. The solution is:

int C = A*B;
