Q:

Indicate what would the SWAP macro be expanded to on preprocessing. Would the code compile?

#define SWAP (a, b, c ) (c t; t = a, a = b, b = t; )

main()

{

    int x = 10, y = 20;

    SWAP (x, y, int );

    printf ( " %d%d ", x, y);

}

Answer

( int t ; t = a, a = b, b = t ;);


This code won't compile since declaration of t cannot occur within parentheses.

Q:

In paper manufacturing, degumming of the raw material is done using

A) sulphuric acid B) bleaching powder
C) caustic soda D) nitric acid
 
Answer & Explanation Answer: C) caustic soda

Explanation:

Paper production is basically a two-step process in which a fibrous raw material is first converted into pulp, and then the pulp is converted into paper. The harvestedwood is first processed so that the fibres are separated from the unusable fraction of the wood, the lignin. Pulp making can be done mechanically or chemically. In the chemical pulping process, alkali (e.g., sodium hydroxide in the form of a lye or caustic soda) is usually used to remove the lignin that binds the fibres. So, for degumming of raw material, caustic soda is used.
