Presentation transcript:

IF if (condition) { Process… } . IF if (condition) { Process… } The if statement checks whether the text expression inside parenthesis () is true or not. If the test expression is true, statement/s inside the body of if statement is executed but if test is false, statement/s inside body of if is ignored…

IF-ELSE if (condition) { Process… } else The if...else statement is used if the programmer wants to execute some statement/s when the test expression is true and execute some other statement/s if the test expression is false.

IF,ELSE IF AND ELSE if (condition) { Process… } else if(condition) if… else if … else if …… else statement is used when program requires more than one test expression.

Switch Case switch(variable) { case value1: process; break; case value2: process; break; . case valueN: process; break; default: process; break; } Decision making are needed when, the program encounters the situation to choose a particular statement among many statements. If a programmer has to choose one block of statement among many alternatives, if… else if … else if …… else can be used but, this makes programming logic complex. This type of problem can be handled in C programming using switch statement.

In C programming, break; is used in terminating the loop immediately after it is encountered. The break statement is used with conditional if statement.
