What is the importance of for loop?

Answer 1

They other day i was sitting in the car, thinking about a script i'm working on. As i sat there i randomnly started wondering how the car was programmed and found that everything must stem from only a few key structures.

while loops: while seatbelt not fastened make beeping sound. while left indicator button flash left indicator.

for loops: for miles driven sum up all the miles. for driving speed do calculation to get average speed.

if petrol tank is running low make beep to indicate
etc etc etc

when i program i am always using for loops. i m currently working on a program that reads a script, recognises from my commenrs if it is new unlearnt code, from comments identifies end of new code block asks me what the code does, prints it to file and then reads the next script in my directory.

for that i need a for loop to read the file and get the line numbers.

a for loop write the code to a file

a for loop to move from file to file in my directory.

for loops just keep popping up everywhere
