What are the subscripts for this array?
Array Subscripts An array subscript allows Mathcad to display the value of a particular element in an array. It is used to refer to a single element in the array. The array subscript is created by using the [ key. This is referred to as the subscript operator.
What is the last legal subscript that can be used with the array?

| The individual values contained in array are known as: | elements |
| By using the same ________ you can build relationships between data stored in two or more arrays. | subscript |
What is the difference between an array’s size Declarator and a subscript?
The size declarator is used in a definition of an array to indicate the number of elements the array will have. A subscript is used to access a specific element in an array.
Can an array subscript be less than 1?
Subscript range from s 0 to s 1. This denotes all elements whose subscripts range from the expression s 0 through s 1(s 0 must not be greater than s 1). For example, if the variable vec is a 10-element vector, vec[4:8] is a five-element vector composed of vec[4] through vec[8].
What are subscripts used for?
Subscripts are commonly used in chemical formulas. A scientist would write the formula for water, H2O, so that the 2 appears lower and smaller than the letters on either side of it. That’s what subscript is for, to set certain characters apart from others.
What is index or subscript in array?
Subscript refers to the array occurrence while index is the displacement (in no of bytes) from the beginning of the array. An index can only be modified using PERFORM, SEARCH & SET.
Does the preprocessor executes after the compiler?
The preprocessor executes after the compiler. If you do not follow a consistent programming style, your programs will generate compiler errors. T. Floating point constants(e.g., 29.6) are stored in memory as doubles.
What will the following C ++ 11 code display?
What will the following C++ 11 code display? It creates a vector object with a starting size of 10 and all elements are initialized with the value 2.
What is the subscript of the last element?
The subscript of the last element in a single-dimensional array is one less than the total number of elements in the array. The contents of an array element cannot be displayed with cout. Subscript numbers may be stored in variables. You can write programs that use invalid subscripts for an array.
What is the subscript of the first element in the array?
[0]
The subscript which specifies a single element of an array is simply an integer expression in square brackets. The first element of the array is a[0], the second element is a[1], etc.
What type and range must an array subscript have?
Solution: An array’s subscript must be an integer type with range from 0 to n-1, where n is the array’s size.
When do you use subscripts in an array?
Array Subscripts. When an array element is referenced, the subscript expression designates the desired element by its position in the data. The first element occupies position zero, the second position one, and so on.
Can a subscript be considered an integer in C?
The subscript itself can be any legitimate C expression that yields an integer value, even a general expression. Therefore, arrays in C may be regarded as collections of like variables.
Which is size declarator indicates the size of an array?
An array’s size declarator can be either a literal, a named constant, or a variable. This indicates the number of elements, or values, an array can hold. Nice work! You just studied 53 terms!
How does C interpret an unsubscripted array name?
C interprets an unsubscripted array name as the address of the array. In the following example, the first two lines set xto equal the value of the first element of the array. The third and fourth lines both set ptequal to the address of the array.
