The program is missing two instructions and two instructions

The program is missing two instructions and two instructions are wrong. What instructions are wrong and what instructions are missing? What function does the program perform? What is the unit of the answer?

Solution

By contrast, higher level languages such as “C”, C++, Pascal, Cobol, Fortran, ADA and Java are called “compiled languages”. In a compiled language, the programmer writes more general instructions and a compiler (a special piece of software) automatically translates these high level instructions into machine language. The machine language is then executed by the computer. A large portion of software in use today is programmed in this fashion.
