Why are strings immutable in programming languages?
Strings are immutable in programming languages because it helps ensure data integrity and security. Immutable strings cannot be changed once they are created, which prevents accidental or malicious alterations to the data they represent. This makes strings more reliable and easier to work with in complex software systems.
What are the benefits of using n in programming languages?
Using n in programming languages allows for the creation of pointers, which are variables that store memory addresses. This can lead to more efficient memory usage and faster program execution, as well as the ability to manipulate data directly in memory. Additionally, pointers enable the implementation of complex data structures and algorithms, making it easier to work with large amounts of data.
What do computer scientists do?
Computer scientists use computers (of course). They also use logic and programming languages to "talk" to the computers. The programming languages that are in common use are: Pascal, C, C++, C#, Java, J++, BASIC, Fortran, Visual Basic among others.
Can you create a program using SQL?
No you can't. SQL is not a programming language, so it doesn't create programs. It is a query language, and it creates queries. There is a difference. There are various things that programming languages have and that they can do, which would take a more detailed explanation to define. SQL is very limited in what it can do, being specifically designed to work with data and manipulate databases. It does not have the capabilities of a programming language. A query and a program are both a list of commands to do a task, but a program is far more extensive and can do far more things, and so it is very different to a query.
What is High Level Language Programs?
High-level language programming is usually a mixture of words or phrases of the English language. High-level languages have several advantages over machine or assembly languages; they are easier to learn and use, and the resulting programs are easier to read and modify. A few of the High-level programs are Ada, ALgol, BASIC, COBOL, C, C++, FORTRAN, LISP, Pascal and also Prolog.
Why you need java programming?
You don't. There are hundreds, nay thousands, of programming languages, Java is just one of them. Programming languages are used to make computer programs (software); software is basically what makes computers work.
What is the programming language to run a real time process control system for a manufacturing plant?
I am pretty sure that most programming languages will work for this.
What are the disadvantages of advanced programming languages?
Taking the time to learn about advanced programming languages could cut into the timing of personal activities that should take more priority - like school and work. Advanced programming languages are also difficult to understand for novice programmers. Other obscure disadvantages lie in advanced programming - but the overall advantages outweigh them by a longshot.
How does loop work?
In programming, a loop works by conditionally jumping to the start of the loop and repeating the instructions. If the condition evaluates false, execution continues to the next instruction, thus breaking out of the loop. We can also break out of a loop from within the body of the loop itself using another conditional jump which jumps out of the loop. If we jump backwards out of a loop we effectively create an intertwined loop, known as spaghetti code which is difficult to read and maintain. Structured loops help make it easier to digest the logic. In C, a jump is achieved using a goto and a label. However, structured loops using for, while and do-while statements make loops much easier to read and maintain.
Is there any possibility that computers work without any programming language?
No. Computers are machines and require machine code to work. Machine code is a programming language. All other languages have to be converted to machine code in order to work.
Which pair of loops causes a statement or set of statements to repeat as long as a condition is true?
A while loop repeats until the condition becomes false, and may never execute: int a = 4; while (a > 5) { //Do something } or int a = 4; while (a > 0) { //Do something a--; }
How does a WHILE loop work in GML?
The while loop works as follows:{while( [expression is true] ) {//Do this code}}The while loop re-runs until the expression contained within the parentheses is false. Take a look at this example:{while(!place_meeting(x,y,obj_ground)) {y += 1;}}This while loop tells the object to move down one pixel until it collides with obj_ground. Unfortunately, nothing guarantees that this loop will not run forever. Always make sure that when you construct a while loop that you make sure that it does not run forever. Take a look at this whileloop:{while(obj_ball.y < y) {draw_sprite(sprite_index,0,x,y);}} This while loop will run for ever. Why? It does not have any statements that insure that the while loop aborts. Again, Always make sure that when you construct a loop that you put statements in the loop that will eventually abort the loop. y -= 1; is the statement in this new while loop that eventually aborts the loop:{while(obj_ball.y < y) {draw_sprite(sprite_index,0,x,y); y -= 1;}}
How does java command while true work?
The contents of a while loop will always execute if the statement between the while parentheses resolves to a boolean true. Hence, if you place "true" as the while statement, the loop will execute forever (until the loop is forcefully broken or the computer or process shuts down).
Is it possible for a person who is strong at mathematics to be better at programming languages?
Yes. It's mainly question of hard work: learning and practising.
How does the mutate function work in programming languages?
The mutate function in programming languages is used to change the value of a variable or data structure. It allows you to modify the content of a variable without creating a new one. This can be useful for updating information or making adjustments to data within a program.
Can you use and or and not on a database?
"AND", "OR" and "NOT" are logical keywords that can be used in databases. They can be used in Query languages and programming languages to work with a database. The three keywords can be used in different combinations. So you could have AND and also AND NOT as combinations to achieve your requirements. With experience you would learn how to used them in the most efficient ways."AND", "OR" and "NOT" are logical keywords that can be used in databases.

Which looping structure does not work in FORTRAN?
Unlike many programming languages that generally support for-loops, while-loops and until-loops or some variant of the three, FORTRAN has only one loop structure: the do-loop, which corresponds to a for-loop.The general form of the FORTRAN do-loop is as follows:do label var = expr1, expr2, expr3statementslabel continueWhere, var is the control variable (or loop index), expr1 is the initial value of var, expr2 is the terminating bound of var, and expr3 is the increment of var. The label must be an unique integer value (usually labels begin at 10 and increment by 10 for all subsequent labels), and denotes the end of the statement or statements that constitute the loop body.Modern variants of FORTRAN also allow the use of an end do statement which permits the label clause to be omitted completely.Although FORTRAN has no concept of either a while-loop or an until-loop, these loops can be simulated using label, if and goto statements:while-loop:label if (logical expr) then statementsgoto labelendifuntil-loop:label continue statementsif (logical expr)goto label
