Final answer:
To format an integer using two columns, one would use a placeholder format control string such as %2d in many programming languages, which ensures that the integer occupies at least two spaces, complying with the formatting requirements for paper size, margins, and font.
Step-by-step explanation:
To display an integer using exactly two columns, we can create a format using a placeholder that aligns with the formatting requirements provided.
Since we're dealing with integers and a specific format, we must consider that integers are comprised of the digits 0-9 and can have a decimal point, which is implied to be at the end if not specified. However, for the purpose of a two-column display without decimals, the point can be ignored.
Given that we need to adhere to specific formatting requirements such as using 8 1/2 x 11" white paper, 1-inch margins, and a legible 12 font style, the desired format control string must take these into account when setting up the table. A common format control string that can be used in many programming languages is %2d for integers, where '%' signifies the beginning of a placeholder, '2' represents the minimum number of characters the integer should occupy, and 'd' denotes that the input is an integer.
The following is a simple example of such a format control string in effect:
5 (this integer is displayed using two spaces)\\ 12 (this integer is also displayed using two spaces)
Ensure the numbers are right-aligned if the given formatting preference dictates. This can typically be done using word processing software or appropriate coding within a computer program.
