Write the syntax for the declaration of a function. Also discuss the parameter passing methods with an example program. 10m Dec2007

Explanation of FUNCTION: A function is a block of code that has a name and it has a property that it is reusable i.e. it can be executed from as many different points in a C Program as required. Function groups a number of program statements into a unit and gives it a name. This… Read More »

Explain the basic principle of Quine-McCluskey method of simplifying the Boolean expression with the help of an example function. 6m Jun2007

Explain the basic principle of Quine-McCluskey method of simplifying the Boolean expression with the help of an example function. 6m Jun2007 Quine McKluskey Method A tabular method was suggested to deal with the increasing number of variables known as Quine McKluskey Method. This method is suitable for programming and hence provides a tool for automating… Read More »
