The number of values a variable can store at a time depends on the data type of the variable. For example, a variable of type int (integer) in many programming languages can store a single integer value at a time. Similarly, a variable of type float (floating-point number) can store a single floating-point value. Other data types like arrays or lists can store multiple values at a time. The capacity of a variable to store values is determined by its data type and memory allocation.

In basic c language structure what is variable?
Variables are named memory locations that may be used to store and retrieve values for use later on in a program. They are like memory locations you have in your brain to remember certain things. Variables may (in general) store a single value at a time, but may be erased with other values (one at a time).
In C programming a character variable can at a time store how many characters?
You can store one, however if you make a char array: char[50]; You can make a string out of your array of characters.
How array differ from ordinary variable?
ordanry variable store one value at a time. arrays are used for storing more than one value at a time in a single variable name ordanry variable doesnt have subscript. array must have subscript syntax for ord. variable Datatype v1,v2...... syntax for array variable Datatype v1[n1],v2[n2].....
How can you change the value of a constant variable in C?
You can change a static variable by putting the static variable into a function that has operations that you intend to execute upon the variable. Example, you want to change the static variable to another value or make an addition of 2. Put the source code inside a function with the static variable declared locally within the function.Every time you call the function, the static variable value will change. Take note that the static variable retains the last value you declared it in your function call.A more terse answerLocal variables declared as static are changed as normal; they are special in that their values persist across function calls.
What is the difference between array element and variable?
• Array is the set of an multiple values where as variable can store single value at a time.• The difference between the definition of array and ordinary variable is the, array is always declared, initialized, and accessed using subscript whereas ordinary variable do not have any subscript.• The syntax for ordinary variable definition is data_type v1, v2, ….;• And the syntax for array variable is data_type v1[N1],v2[N2],…; where v1,v2 are name of variable and N1, N2 are the integer constants indicating the maximum size of array.
How many character can store a character variable at a time?
One. If you want more, use an array.
How do you determine the processing time of a java insertion sort program?
You store the starting time to a variable, run the process, store the end time to another variable, then subtract.
How are independent and dependent variable related?
Independent variables can take values within a given boundary. The dependent variable will take values based on the independent variable and a given relationship at which the former can take its values.

Why must numeric values be assigned to variables when comparing results?
In order to compare any two values, both values must be stored somewhere otherwise it would be impossible for the machine to refer to those values let alone operate upon them. Typically we store variables in main memory, however values can also be stored directly in the machine's registers. These are known as register variables and the only practical difference between a register variable and an ordinary variable is that we cannot take the memory address of a register variable (because it has no address to take).If we can take the address of a variable then that variable is said to have identity because it exists in memory and we can identify it solely by its address. When comparing values that have identity, we can either compare the values themselves or we can compare their identities. The latter helps us determine whether two values are the same variable or not.The address of a variable may or may not be known at compile time. If the address is known at compile time then we can name the variable and refer to it by either its name or its address. Variables generated at runtime are anonymous and can only be referred to by their address (which we must store in another variable known as a pointer variable). Conversely, register variables must always be named, but they have no identity.Regardless of whether a variable has a name, an identity, or both, the machine simply cannot operate upon values without using variables.
What are dependent and independent variable in algebra?
the dependent variable is the y-value. the dependent variable means it relys on another variable for its answer. without the other variable this variable would not exist. the independent variable is the x-value. the independent variable can exist on its own without the dependent variable. i mention x-values and y-values... this is only if you are using an x and y value for your application. there are other applications... like speed... where the dependent variable for speed would be time and the independent variable for speed would be distance. and for acceleration the dependent variable would be speed and the independent variable would be distance.
What is an independent variable in algebra?
The variable which is controlled.On a graph, the independent variable is on the x-axis (horizontal) and the dependent variable is on the y-axis (vertical).When we choose a value of x, the value of y depends on the x-value we chose.For instance, if we record the temperature every hour, time is the independent variable because we control the values. The temperature (which is measured) is the dependent variable because it depends on the time.
What is average over time?
Average over time refers to the calculation of the mean or average value of a given variable over a specific period. This involves adding up all the values of the variable during that period and dividing by the number of observations. It helps in understanding the trend or behavior of the variable over time.
What is an independent variable and example?
Independent variables are values that can be changed in a given model or equation. They provide the "input" which is modified by the model to change the "output."A scientist studies how many days people can eat soup until they get sick. The independent variable is the number of days of consuming soup. The dependent variable is the onset of illness.The independent variable is what causes the results.
What is Seasonal variation?
Variation in the values of a variable dependent upon the time of the year is seasonal variation. A variable having seasonal variation exhibits a pattern that repeats after exactly one year.
In C programming a character variable can at a time store how many characters?
You can store one, however if you make a char array: char[50]; You can make a string out of your array of characters.
