elvis10ten: Here is a simple php challenge: Write a program that will print all the products of 7 till 300 in the format "7 x 1 = 7, 7 x 2 = 14, ..., 7 x 300 = 2100". RULES 1)Only for loop is allowed. 2) Do not use "*"(multiplication sign), rather use "+"(addition) to compute the product 3)Running your script on www.ideone.com is a plus. 4)Your script should not waste much time and run on a moderate cpu.
THE SHORTER THE CODES THE BETTER.

Judinho59: No '*'..

figure = int(raw_input( "Number: " ))
multiple = int(raw_input( "How many multiples?: " ))
initial = figure
for i in range (0, multiple):
    print figure
    figure += initial

humanbean: Just started delving into programming. I don't know PHP but I took up your challenge in Python. The code is a function to accept any number from the user and output any number of multiples he desires. I used a for loop and addition as you asked, but I don't know how to test the cpu load. The main code is about 4 lines. Please point out how I can optimise this.

def maths():
figure = int(raw_input("Number: ")
multiple = int(raw_input("How many multiples?: ))
initial = figure
for i in range (0, multiple):
print figure
figure += initial
maths()

obadiah777: QUESTION TO ALL YOU GENIUSES. WHAT WOULD BE THE BENEFIT OF A PROGRAM LIKE THIS ? OF WHAT USE WOULD IT BE ? HOW WOULD IT BE APPLIED TO EVERYDAY STUFF ? LIKE DOES IT WORK WITH CASH MACHINES OR CALCULATORS ETC ETC ? THANKS IN ADVANCE.
