4.2.6 Control Structures

Control structures allow to change the program completion depending on expressions, variables or

external influences.

4.2.6.1 Conditional Valuation

With a conditional valuation expressions can be generated which will be conditionally calculated.

The form is:

( Expression1 ) ? Expression2 : Expression3

The result of this expression is expression2, if expression1 had been calculated as unequal 0, other-

wise the result is expression 3.

Examples:

a = (i>5) ? i : 0;

a= (i>b*2) ? i-5 : b+1;

while(i> ((x>y) ? x : y) ) i++;

4.2.6.2 do .. while

With a do .. while construct the instructions can depending on a condition be repeated in a loop:

do Instruction while( Expression );

The instruction or the Instruction Block is being executed. At the end the Expression is evaluated. If

the result is unequal 0 then the execution of the expression will be repeated. The entire procedure

will constantly be repeated until the Expression takes on the value 0.

Example:

a=a+2;

while(a<10);
