If-thenif-else if Cl then B1 thenif C2 then B2 thenif Cn then Bn else D endir If-thenif-else is a control structure that is not directly implemented in programming languages. So, if we need this control structure we must make it using those control structures that are available in a given language. Using a simple if-else statement available in C and similar languages, and auxiliary variables, write a segment of code that implements this control structure. Try to make your solution simple, and general
