Array problems

[lzhaol]

Hi all C++ gurus
i have a little problem with my codes
basically i have 5,6,7,8,9 in my array

i m supposed to come up with a program that will run through the numbers in the array...if any number that is more than 7 will be replaced by 7

therefore it should look like this

original: 5,6,7,8,9
sorted: 5,6,7,7,7

however when i run
it looks like this

original: 5,6,7,8,9
sorted 5,7,7,7,0

can anyone pls help with me this becoz i m rather new in c++??
thanks
