What is the difference between for and foreach loop?

foreach loop or statement is same as for loop or statement with a slight difference.In foreach loop , loop irterate through array and collections. Unlike for loop, foreach loop does not have test condition means it does not check any condition.
Example:

foreach Loop:

foreach( data_type data_variable in collection_name)

{

// your code

}

for loop:

for(data_type variable ;condition;update )

{

// your code

}
