For the following programming problems, you need to time a section of code in C++. For example, the following statements time the execution of the function doSomething: #include clock_t start = clock() ; doSomething () ; clock_t finish = clock() ; double overallTime = static_cast (finish - start) / CLOCKS_PER_SEC; 3 1. Consider the following two loops: // Loop A for (i = 1; i
