A6 - iteration

for loop

for ( int i = 0; i < N, i++) { /* (intex initialisation; condition; step) */
	...; /* statements */
}

• the step can be negative: i--; or more than 1: i += step
• the scope of the index variable is only within the block
• they can be nested

while loop

while (condition) {
	...; /* statements */
}

do-while loop

do {
	...; /* statements */
} while (condition) ;

• note that the body is executed at least once as the condition is executed after the body

control statements

• change the normal flow of execution
