measure time elapsed Algorithm
The measure time elapsed algorithm, also referred to as a timer or stopwatch algorithm, is a computational method used to quantify the amount of time it takes for a particular process or function to execute. This algorithm is of great importance in computer science and engineering, as it helps developers understand the efficiency and performance of their code, enabling them to optimize and improve it. By calculating the difference between the start and end times of a specific process, the algorithm provides a precise measurement of the time elapsed, which can be expressed in various units such as seconds, milliseconds, or even nanoseconds.
To implement the measure time elapsed algorithm, a developer typically records the current time (also known as a timestamp) immediately before the execution of the function or process they wish to analyze. Next, the algorithm proceeds to execute the desired function or process. After the process is completed, the algorithm records another timestamp. By calculating the difference between the two timestamps, the algorithm effectively measures the amount of time taken for the process to run. This information can be invaluable for developers looking to identify bottlenecks, optimize their code, and ensure the smooth operation of their software. Additionally, the measure time elapsed algorithm can be used in a wide range of applications, from simple time tracking tools to complex performance analysis systems.
// To calculate the time taken by a code to execute
#include <sys/time.h>
#include <iostream>
__int64_t getTimeInMicroseconds() {
struct timeval start;
gettimeofday(&start, NULL);
return start.tv_sec * 1000000 + start.tv_usec;
}
// write function sample(args)
int main() {
// write code
__int64_t starttime = getTimeInMicroseconds();
// sample(args) function run
// Any other functions (if present) run
std::cout << getTimeInMicroseconds() - starttime;
}
