How for Loop Works
the first element of the sequence is assigned to the variable written after for and then the statements are executed nest the second element of the sequence is assigned to the variable and then the statement are executed second time. in theis way for each element of the sequence the statement are excuted onece so the for loop is executed as many time as there are number of elements in the sequence.
All statements and instructions in a program are built with tokens.
