Print 10 times print the even numbers between 10 and the value of n while and do loops are more natural when we want to keep looping until some outcome indefinite or result controlled loops. This determines the type and size of data associated with variables. The c compiler combines the capabilities of an assembly language with the features of a highlevel language and therefore it is well suited for writing both system software and business packages. In machine language, there are no if statements or loops we only have branches, which can be either unconditional or conditional on a very simple condition with this, we can implement loops, if statements, and case statements.
With this, we can implement loops, if statements, and case. Use of types name, scope, and binding names binding. This sequence of statement to be executed is kept inside the curly braces known as loop body. For example, when you are displaying number from 1 to 100 you may want set the value of a variable to 1 and display it 100 times, increasing its value by 1 on each loop iteration.
