In the programs that we have examined to this point, each of the statements is executed once, in the order given. If the condition does not exist, the action is not performed. Programs generally run from the top down.
It's often helpful to think about conditional statements in spoken language: On that computer it could be implemented quite efficiently using instructions such as 'branch if accumulator negative'. We could also call these rules conditions—if one thing happens or doesn't happen, then another thing happens or doesn't happen.

A technical blog which provides the computer science study material for gate (cs/it) preparation. The basis for education in the last millennium was reading, writing, and arithmetic; now it is reading, writing, and computing. As a program becomes more sophisticated, it must be able to make decisions about what commands it should execute. Conditional statements allow us to change the way our program behaves based on the input it receives, the contents of variables, or any of a number of other factors.
