I. Conversion of reference parameters and pointersStandard C does not support reference parameters, which need to be converted. The following is an example of the Destroytriplet () function in Bo1-1.cpp and bo1-1.c to illustrate this conversion.The

The rapid development of computers in multicore technology is much faster than the increase of single-core computing power. Thus, designing concurrent programs becomes a powerful tool to improve software performance.Although the concurrent program
