When was the for loop invented?
As it turns out, from the Swiss mathematician Heinz Rutishauser, who in 1951 coined the term für as a keyword in his high-level compiler Superplan. Later, when Rutishauser developed ALGOL in 1958, he decided to anglicize it to “for”.
Who discovered for loop?
The for loop has been part of the C language since the early 1970s (or late 1960s), but the DO loop has been a part of Fortran since it was developed in the mid-1950s (by John Backus and his team at IBM).
What is the history of coding programming?
The late 1950s saw the invention of coding languages that are still in use today – specifically, FORTRAN, LISP and COBOL. Technology swiftly unfolded throughout the 60s, with the notion of computer gaming being born, the mouse being invented, and ARPANET, the predecessor to the internet, being created.
What are the loops in programming?
In computer programming, a loop is a sequence of instructions that is repeated until a certain condition is reached. An operation is done, such as getting an item of data and changing it, and then some condition is checked such as whether a counter has reached a prescribed number.
Who wrote the first program in history of computers and recognized the importance of looping?
About a century before Konrad Zuse designed the first programmable computing machine, in the 1840s, Ada Lovelace wrote the first computer programme in the world. From a modern perspective, her work is visionary.
Why are loops useful in programming?
Definition: Loops are a programming element that repeat a portion of code a set number of times until the desired process is complete. Repetitive tasks are common in programming, and loops are essential to save time and minimize errors. Why We Use Loops: Loops make code more manageable and organized.
What was the first programming language written in?
What was the first widely used programming language? Assembly Language appeared in 1949 and soon saw wide use in Electronic Delay Storage Automatic Calculators. The Assembly was a low-level computer language that simplified the language of machine code ie. the specific instructions necessary to operate a computer.
What was the first high level programming language?
After World War II, Grace Hopper worked on the first commercial computer called the UNIVAC. In 1953 she invented the first high level programming language, A-0, that used words and expressions to program the UNIVAC. She also created the first modern day compiler and coined the phrase BUG.
What is looping in C++ program?
In case of a conditional statement, the statement is executed depending on the result of the condition. In addition, you can use looping statements in C++ when you want to repeat the execution of a specific block of code till a specific condition is satisfied.
What is history of computer?
In the early 1820s, it was designed by Charles Babbage who is known as “Father of Modern Computer”. It was a mechanical computer which could perform simple calculations. It was a steam driven calculating machine designed to solve tables of numbers like logarithm tables.
What is the history of computer and its generation?
Classification of generations of computers
| Generations of computers | Generations timeline | Evolving hardware |
|---|---|---|
| First generation | 1940s-1950s | Vacuum tube based |
| Second generation | 1950s-1960s | Transistor based |
| Third generation | 1960s-1970s | Integrated circuit based |
| Fourth generation | 1970s-present | Microprocessor based |
