What else can I help you with?
Is it true that a variable is a storage location in memory that is represented by a name and can hold different values during the execution of the program?
Yes, this is correct. In terms of the compiled machine language, the variable represents a memory location. So, anytime the variable is referenced, and you either set the variable to a value, or retrieve a value from the variable, you are actually referencing the memory location pointed to by the variable.
What are variables in programming?
In computer programming, variables refer to a particular location in the memory that holds a value. Variables are equivalent to their assigned values.
What is distinct in SQL language?
distinct keyword displays only unique values. eg.if there is a deprtment_id called 140 for thrice means it will diaplays only once. select distinct department_id from departments
Does a bar graph have gaps?
Yes, a bar graph typically has gaps between the bars. These gaps indicate that the data represents distinct categories, emphasizing that the values are not continuous. In contrast, a histogram, which displays frequency distributions, does not have gaps because it represents continuous data.
Write a program that takes 5 numbers 1 to 10 from user and then prints the number of distinct values?
The simplest solution is to use a std::set<size_t> sequence container to store the values as they are input. Duplicate entries are ignored automatically, thus when all 5 numbers have been input, the set will have at least 1 number but no more than 5. Thus the size of the set represents the count of distinct values that were input.
What is the purpose of using arrays in C language?
The purpose of using arrays in C is to store multiple values in one variable. Then you can make programs that use arrays like lists, printing values from multiple arrays into one line. It take memory in continues block then we can know memory location easily. We can retrieve data quickly.
How many distinct values can we represent with 5 bits?
32 values. 2^5=32
What is x axis?
The darker horizontal line on a graph. It represents the x-values. The lighter vertical line is the y axis. It represents the y-values.
What is the difference in function calling by value and calling by reference?
Call by Value:- In this method a copy of the variables is created and is updated time to time but not the actual memory location is updated.so when we make a call to the function we get old valuesCall by Reference:- In this method we access the variable by the reference of the memory location,so when we make call to the variable we get the updated values.
What is sbyte?
An sbyte (signed byte) is a data type in programming languages like C# that represents an 8-bit signed integer. It can hold values ranging from -128 to 127. The "signed" aspect means it can represent both positive and negative numbers, unlike an byte, which only represents non-negative values from 0 to 255. sbyte is often used in scenarios where memory efficiency is important and the range of values fits within its limits.
What graph is made up of only distinct points?
A graph made up of only distinct points is typically referred to as a scatter plot. In a scatter plot, each point represents a unique pair of values, often corresponding to two variables, allowing for the visualization of relationships or trends between them. Since each point is distinct, no two points can occupy the same coordinates in the graph.
What are the distinct?
Distinct means any two values or any two numbers are not equal For example X=1,X=2 2is distinct point
