Repetitive control structures for techniques of passing arguments are determined.
"Loops" are considered to be the repetitive control structures. They can either be event-controlled or counter controlled. The following are some of the repetitive counter controlled structures:
1) "for" loop
2) "while" loop
3) "do-while" loop
In this kind of loop, the loop body executes some fixed number of times according to the condition specified. A for loop header consists of an initialization statement, a condition and an increment statement; out of which the initialization and increment statements are optional.
This loop is basically used to perform repetitive action where count of repetition is known beforehand.
for( int i=10; i <= 50 ; i =i + 5)
This loop starts from i = 10 and execute till i becomes 50 with the increment of 5 after each iteration.
In this case, the loop body executes until the condition is true in while structure. In the example given below, the variable i is declared out of the while structure and the statements in while loop are executed as long as the variable is less than 50. In the while loop, we have to provide some statement to break the condition so that it will not go into infinite loop. For the same reason the variable i is incremented at the end of loop body in the example.
Do-while loop is similar to while loop except that the statements are executed at least once before the condition is checked. Like in the below given example, the statement is executed for the first time without checking the condition of the do-while statement. Even if the variable i is greater than ...
