Question

Explain with a flowchart the following control structure:

Iteration Logic

Answer 1

The repeat for loop has the following form,

Form:

Repeat for K = R to S by T [Module] [End of loop]

where K = Index variable

R = Initial value of K

S = Final value of K

T = Step (increment/decrement)

The loop is executed for all values of K starting from R to S with a step of T.
It uses a condition to control the loop.

Form:

Repeat while condition: [Module] [End of loop]

The loop continues till a condition is true. There must be an initialisation statement, and there must be a statement that will change the index variable in the loop.
