Write a loop which will be increasing variable i by 5 at each iteration till i reaches 50. Initial value of i is 12.

im having a bit trouble with loops if somone can help me with this answer and explain as well it would be nice

Answer 1

[Walter Roberson]

for VARIABLENAME = FIRST_VALUE : INCREMENT : LAST_VALUE
    something
end

is nearly equivalent to

VARIABLENAME = FIRST_VALUE;
while VARIABLE_NAME <= LAST_VALUE
    something
    VARIABLE_NAME = VARIABLE_NAME + INCREMENT;
end

(The differences between the two have to do with the value that VARIABLENAME is left at if FIRST_VALUE > LAST_VALUE when INCREMENT is positive, or FIRST_VALUE < LAST_VALUE when INCREMENT Is negative; and also have to do with the value that VARIABLENAME will be left with after the last iteration in two different situations.)
