#Mastery20 Use of loops with for

#Mastery20 #TC1017

The for repetition structure handles all the details of counter-controlled repetition. The picture shows an example.

The general format of the for structure is

for ( initialization statement; loop continuation condition; increment )

When the for structure begins executing, the control variable i is declared and inicialized to 0. Then, the loop-continuation i <= size is checked. The inicial value of i is 0, so the condition is satisfied and the body statement prints the value of i, namely 0. Then the expresion i++  increments control variable i and the loop begins again with the loop-continuation test. The control variable is now equal to 1, so the final value is not exceeded and the program performs the body statement again. This process continues until the control variable i is incremented upper than the value size given by the user- this causes the loop-continuation test to fail and repetition to terminate. The program continues by performing the first statement after the for structure.
