# Write a small program in C++ to time the given algorithm.

Write a small program in C++ to time the given algorithm.

Algorithm: SUM[n=0 to 100] n(n x 3n)(n+1)/(77n - 4)

Hint: you can use a timing function such as:

clock_t begin = clock(); ... clock_t end = clock();

See attachment for a better illustration of the math.

#### Solution Preview

We will use the ctime library function clock() to time the algorithm. The clock() function counts the number of "clock ticks" (CPU time) elapsed since the program was started. The return type of clock() is clock_t, which is defined by ctime to represent clock ticks and supports arithmetical operations (usually long integer ...
