How much memory is my program using C++?

Click on Processes. See the list of Image Names and look for your application or program. Under Mem Usage you can see with respect to your application the memory used in Kilobytes.

How do I know how much memory my program is using?

Run the program in one shell. Open another shell and run ‘top’ command. it will list running processes and home much memory they consume. you can, i guess, poll /proc/yourprocessid/stat to see how much memory it is using over time.

How do you get the memory address of a variable in C++?

In c++ you can get the memory address of a variable by using the & operator, like: cout << &i << endl; The output of that cout is the memory address of the first byte of the variable i we just created.

What is maximum resident set size?

Collectively, the total amount is the virtual set size. The peak resident set size (Peak RSS or Max RSS) refers to the peak amount of memory a process has had up to that point.

How do you track time in C++?

Since C++11, the best way to measure elapsed time in C++ is by using the Chrono library, which deals with time. Following C++ program calculates the time elapsed for a simple code in seconds, milliseconds, microseconds, and nanoseconds. It includes the

How do you calculate execution time of a code snippet in C++?

clock_t startTime = clock(); // some code here // to compute its execution duration in runtime cout << double( clock() – startTime ) / (double)CLOCKS_PER_SEC<< ” seconds.” << endl; However for small inputs or short statements such as a = a + 1, I get “0 seconds” result.

What is a memory location in C++?

The location of an object in the memory is called its address. In C++ there is an address (or referencing ) operator, &, which allows you to obtain an object’s address. Memory locations are determined by the operating system and it is possible that objects’ addresses may be different during repeated runs of a program.

What does RSS stand for memory?

resident set size
In computing, resident set size (RSS) is the portion of memory occupied by a process that is held in main memory (RAM). The rest of the occupied memory exists in the swap space or file system, either because some parts of the occupied memory were paged out, or because some parts of the executable were never loaded.
