How the first computer was coded?
3 Answers. The short answer: the first programs were meticulously written in raw machine code, and everything was built up from there.
What is an if statement processing?
The if processing code is a stand-alone version of the if conditional allowable within an a-correlative. If the condition evaluates to true (nonzero) the a-correlative following then is executed. If there is no then clause a null value is returned on true.
How do computers use conditional statements to work?
Conditional statements are the way computers can make decisions. Conditional statements always have an if part, which tells the app what to do when the condition is true. Conditional statements also usually have an else part, which tells the app what to do when the condition is false.
What is the first part of an IF THEN statement?
The hypothesis is the first, or “if,” part of a conditional statement. The conclusion is the second, or “then,” part of a conditional statement.
What is an if statement for kids?
If then statements are conditionals. A conditional is an action that occurs if something specific happens. If then statements are used in programming to trigger a set of instructions. If then statements can be a difficult concept for young children to understand.
How are computers programmed?
Computer programming is the process that professionals use to write code that instructs how a computer, application or software program performs. Based on the requirements or purposes of these instructions, computer programming can be as simple as adding two numbers.
When was the first computer programmed?
Ada Lovelace wrote the first computer programs (1840s). Lovelace was also the first person to suggest that computers could be more than just calculators. Grace Hopper developed LOW-MATIC, the first system that could convert plain English into computer code (1952).
Why do we use else if?
In JavaScript we have the following conditional statements: Use if to specify a block of code to be executed, if a specified condition is true. Use else to specify a block of code to be executed, if the same condition is false. Use else if to specify a new condition to test, if the first condition is false.
How do I make an if statement variable?
If you’re new to the syntax that’s used in the code sample, if (int i = 5) { is a perfectly valid way of declaring and defining a variable, then using it inside the given if statement. It allows us to write terser, clearer code, while also avoiding limiting the scope of a variable.
Why are conditional statements valuable to programmers?
They provide a way for programmers to add decision-making to a computer program. They allow programmers to specify conditions that must be met for an action to occur. They allow a program to evaluate multiple values within a statement. They allow programmers to set actions that will change the conditions.
What structures use conditional statements?
The IF statement lets you execute a sequence of statements conditionally. That is, whether the sequence is executed or not depends on the value of a condition. There are three forms of IF statements: IF-THEN , IF-THEN-ELSE , and IF-THEN-ELSIF .
What is the history of the computer in education?
Finally, the new emerging educational technologies were to become an important catalyst for rethinking education. The history of the modern computer age is a brief one. It has been about 50 years since the first operational computer was put into use: the MARK 1 in 1944 at Harvard and ENIAC in 1946 at the University of Pennsylvania.
Why is C the first programming language?
It was the first computer language for electronic devices and it required the programmer to change its statements into 0’s and 1’s by hand. Still, it was the first step towards the complex languages of today.
What is the history of Computer-Assisted Instruction?
It spread rapidly and was used for the creation of computer-based instructional materials for a wide variety of subjects and for all levels of education. In 1963, while at Stanford, Patrick Suppes and Richard Atkinson established a program of research and development on computer-assisted instruction in mathematics and reading.
What is the earliest form of a computer language?
Thus, the earliest form of a computer language was physical motion. Eventually, physical motion was replaced by electrical signals when the US Government built the ENIAC in 1942.
