Conditional Operator

Conditional Operator   You can exchange simple if-else code for a single operator – the conditional operator.  The conditional operator is the only C++ ternary operator (working on three values).  Other operators you have seen are called binary operators (working on two values). FORMAT:  conditional Expression ? expression1 :expression2;   ** if the conditional Expression is true, expression1executes, otherwise if the conditional Expression is false,expression 2 executes.  If both the true and false expressions assign values to the same variable, you can improve the efficiency by assigning the variable one time: (a>b) ? (c=25) : (c=45);  can be written as: c = (a>b) ? 25 : 45;

if (a>b) {        c=25;  }  else {        c=45;  } can be replaced with (a>b) ? (c=25) : (c=45); The question mark helps the statement read as follows: "Is a greater than b?  If so, put 25 in c.  Otherwise, put 45 in c."
