Answer 2

The given C++ expression is int a=5, b=7, c; c=a*a+b*b;

The valuable of a and b is 5 and 7 respectively.  

When we substitute the values, we can get the expression which is given below.

Sol c = 5*5+7*7

C = 74.

Hence, the answer to this given C++ expression is 74.

It is important to substitute the values properly before entering the calculations.
