Could 1x1 be an array?
Yes, a 1x1 can be considered an array, specifically a two-dimensional array with a single element. In programming and mathematical contexts, it represents a matrix with one row and one column. This structure can hold a single value, and it behaves like an array in operations, allowing for indexing and manipulation.
How do arrays differ from single memory position variables?
A single memory position variable can store only one value of its type. An array can store n number of values, where n is the size of the array.
Differentiate single dimensional array to double dimensional array?
A single dimensional array is an array of items. A two-dimensional array is an array of arrays of items.
Why do you sometimes have only one multiplication sentence for an array?
An array can represent a multiplication sentence when it has a uniform number of rows and columns. However, if the array has a single row or a single column, it can only produce one multiplication sentence, as it reflects a simple multiplication of one dimension. For example, a 1x5 array can only be expressed as 1 multiplied by 5, while a 5x1 array can only be expressed as 5 multiplied by 1. In these cases, the structure of the array limits the possible multiplication sentences.
What is array What is difference between array and simple variable?
An array stores several values - for example, several numbers - using a single variable name. The programmer can access the individual values with a subscript, for example, myArray[0], myArray[5]. The subscript can also be a variable, for example, myArray[i], making it easy to write a loop that processes all the elements of an array, or some of them, one after another.

How can two single dimensional array values be stored in a third single dimensional array?
You need to create a new array with enough elements to cater for both arrays. Thus if the first array has 10 elements and the second has 5, you must create a 15 element array to store both. You then copy elements from the first array into the third and immediately follow with the elements from the second. Note that the first two arrays must be of the same type. You cannot combine an array of numeric values with an array of strings, for instance.

What is an Excel reference function that looks for a value in the top row of a table or array of values and returns the value in the same column from a row you specify?
hlookup
What is the purpose of array objects in JavaScript?
An array object is used to store multiple values in a single variable. This de-clutters everything and is extremely useful. An array can be created in three ways, regular, condensed and literal.
WHAT IS array in MsExcel?
An array formula can perform multiple calculations and then return either a single result or multiple results. Array formulas act on two or more sets of values known as array arguments. Each array argument must have the same number of rows and columns. You create array formulas in the same way that you create other formulas, except you press CTRL+SHIFT+ENTER to enter the formula.Array constants can be used in place of references when you don't want to enter each constant value in a separate cell on the worksheet.Some of the built-in functions are array formulas, and must be entered as arrays to get the correct results.ex:uding an array formulaTo calculate a single result This type of array formula can simplify a worksheet model by replacing several different formulas with a single array formula.For example, the following calculates the total value of an array of stock prices and shares, without using a row of cells to calculate and display the individual values for each stock.Array formula that produces a single resultWhen you enter the formula ={SUM(B2:D2*B3:D3)} as an array formula, it multiples the Shares and Price for each stock, and then adds the results of those calculations together.To calculate multiple results Some worksheet functions return arrays of values, or require an array of values as an argument. To calculate multiple results with an array formula, you must enter the array into a range of cells that has the same number of rows and columns as the array arguments.For example, given a series of three sales figures (in column B) for a series of three months (in column A), the TREND function determines the straight-line values for the sales figures. To display all of the results of the formula, it is entered into three cells in column C (C1:C3).Array formula that produces multiple resultsWhen you enter the formula =TREND(B1:B3,A1:A3) as an array formula, it produces three separate results (22196, 17079, and 11962), based on the three sales figures and the three months.Using array constantsIn an ordinary formula, you can enter a reference to a cell containing a value, or the value itself, also called a constant (constant: A value that is not calculated and, therefore, does not change. For example, the number 210, and the text "Quarterly Earnings" are constants. An expression, or a value resulting from an expression, is not a constant.). Similarly, in an array formula you can enter a reference to an array, or enter the array of values contained within the cells, also called an array constant. Array formulas accept constants in the same way that nonarray formulas do, but you must enter the array constants in a certain format.Array constants can contain numbers, text, logical values such as TRUE or FALSE, or error values such as #N/A. Different types of values can be in the same array constant - for example, {1,3,4;TRUE,FALSE,TRUE}. Numbers in array constants can be in integer, decimal, or scientific format. Text must be enclosed in double quotation marks - for example, "Tuesday".Array constants cannot contain cell references, columns or rows of unequal length, formulas, or the special characters $ (dollar sign), parentheses, or % (percent sign).The format of array constantsArray constants are enclosed in braces ( { } ). Separate values in different columns with commas (,). For example, to represent the values 10, 20, 30, and 40, enter {10,20,30,40}. This array constant is known as a 1-by-4 array and is equivalent to a 1-row-by-4-column reference.Separate values in different rows with semicolons (;). For example, to represent the values 10, 20, 30, and 40 in one row and 50, 60, 70, and 80 in the row immediately below, you would enter a 2-by-4 array constant: {10,20,30,40;50,60,70,80}.
What is the difference between numeric array and associative array?
Numeric array has numbers(+integers) that represent the values Associative array has strings that represent the values

What is the function to determine the lowest number in a given range of cell in a column if you give other column reference as like as SUMIF function?
You use the MIN with an IF and enter it as an array formula. So say you have regions North, South, East and West, in column A and values in column B. The regions can be repeated multiple times. So the function would be as follows to find the lowest for the North region:=MIN(IF(A2:A25="North",B2:B25))When you type it, then press Ctrl-Shift-Enter to put it in as an array formula, rather than just the Enter key.You use the MIN with an IF and enter it as an array formula.

Can you write a C program to find the sum of a given column in a 2D array?
Use the following function to find the sum of a given column in an array of integers: int sum_column (int** array, unsigned int rows, unsigned int columns, unsigned int column) { assert (column<columns); int accumulator int row; accumulator = 0; for (row=0; row<rows; ++row) { accumulator += array[row][column]; } return accumulator; }
