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.
