What is arithmetic expression . mention different types of arithmetic expressions?
An expression that represents a numeric value. Other types of expressions can represent character or Boolean values.
Why do you need signed and unsigned integer?
We need signed integers in order to represent both negative and positive values. However, some numbers can never be negative. For instance, the size of a file must always be greater than or equal to zero so we use unsigned integers to represent file sizes. Also, natural numbers must be greater than 0 so there's no point in using a signed value to represent a natural number. Signed integers also use one bit to denote the sign, but unsigned integers do not thus unsigned integers can effectively represent twice the range of positive values than an unsigned integer can. For instance, an 8-bit signed value can represent values in the range -128 to +127 using twos complement notation, but an 8-bit signed value can represent values in the range 0 to 255.
Minimum size of stack to evaluate postfix expression?
Scan the postfix expression from left to right and count the number of values and the number of operators. The maximum value of their difference is the required stack size. Eg: 1 2 3 + 4 + * 1 2 3 2 3 2 1 The maximum is 3.
Does int mean interface in programming language?
No. In most programming languages int is a keyword used to represent integer numeric values.

What do letters and number represent in Microsoft Excel?
They can represent values in cells. They also can represent columns (letters) and rows (numbers).
How many different values can 1 bit represent?
Two: '0' or '1'
Could 9.10 be written as 9.01?
No because they represent two different values
What is the largest number that can be represented by a single bit in binary?
1. A single bit can represent two different values, 0 and 1. Then simply take the largest of those two possible values, 1, and that's your answer.
Is the range zero in a data set consisting of 1000 values that are all different?
No. The range is the maximum value less the minimum value. If all the values are different, the maximum must be different from the minimum. Consequently, the max minus min must be greater than zero.
What is the name for the difference between the minimum and the maximum values in the 5-number summary?
Range.
What is the name for the difference between the minimum and maximum values in a five number summary?
The range
What does the letter n represent in maths?
In math, the letter "n" is commonly used as a variable to represent a number that is not specified. It is often used in equations and formulas to indicate a variable quantity that can take on different values.
What is intensity values?
Intensity values refer to the brightness or amplitude of a pixel in an image. These values typically range from 0 (black) to 255 (white) in grayscale images and can represent different colors in color images. High intensity values correspond to brighter pixels, while low intensity values represent darker pixels.
What is the significance of the number "0" in Roman numerals?
The number "0" does not have a specific representation in Roman numerals. Roman numerals were based on a system of adding and subtracting values of different symbols, so there was no need for a symbol to represent zero.
