Q:

What would be the output of the following program?

# define SQR(x) (x * x)

main()

{

    int a, b = 3;

    a = SQR ( b + 2 );

    Printf ("\n %d ", a );

}

Answer

11


Because, on preprocessing the expression becomes  a = ( 3 + 2 * 2 + 3),  as Ist preference is multiply & then addition, it evalvates as(3+ 2 * 3 +2) = (3+6+2)=11.

Q:

What occurs during the appropriations process?

A) Congress acquires requested oversight material from the executive. B) Congress instructs the president to eliminate federal agencies.
C) Congress grants funds to federal agencies. D) Congress makes laws.
 
Answer & Explanation Answer: C) Congress grants funds to federal agencies.

Explanation:

Appropriations are annual decisions made by Congress about how the federal government spends some of its money. In general, the appropriations process addresses the discretionary portion of the budget – spending ranging from national defense to food safety to education to federal employee salaries, but excludes mandatory spending, such as Medicare and Social Security, which is spent automatically according to formulas.

 

Hence, congress grants funds to federal agencies and programs during the appropriations process.
