How can I implement a timer in Fortran to measure the execution time of my program?
To implement a timer in Fortran to measure the execution time of your program, you can use the SYSTEMCLOCK function. This function returns the current processor time, which can be used to calculate the elapsed time. You can call SYSTEMCLOCK before and after the code segment you want to measure, and then calculate the difference to determine the execution time.
How do you call an external function or program that is written in different programming language?
It doesn't matter what language the external program or function was written in since all executables must be converted to machine code. To execute an external function, that function must reside in a library to which your program is linked and you must know the prototype of the function you intend to call. This is usually found in the library header file which can simply be included in your program. You can then call the external function just as you would an internal function. To execute a specific function in another program, however, you must use the command line interface for that program.
How do you call an external function or program that is written in a different programming language?
This depends on too many variables you didn't specify for us to answer.
Where is the fuction call of main function?
The main function is the entry point into a program. When the Operating System launches the program the main function gets executed.
How you write a c program for making a call in gcc?

What is the use of function in c?
using function we can call the function in the program any where. by using functions we can reduce the code redundancy
How is a procedure identified as near or far?
The far procedure is used at the place where the function call is given in main program and function definition is given in sub program....
What is the main function of C?
The main function is the entry point for the application. Each program written in C or C++ will start at the first line in the main function, and cease execution once the main function returns control to the operating system (either via a return keyword in the main function, an exit(3) function call, or by "running off" the end of the main function). A program will not compile if it is missing the main function. Some variants of C++ have an alternate entry point (including those written for Microsoft Windows).
What is a call in programming and how does it function within the context of software development?
In programming, a call refers to invoking a function or method to perform a specific task within a program. When a call is made, the program transfers control to the function being called, executes the code within that function, and then returns control back to the point in the program where the call was made. Calls are essential in software development as they allow for code reusability, organization, and modularization, making it easier to manage and maintain complex programs.
How do you write a program that will call a function to multiply 4 numbers and return the answer to main program?
In Windows, use notepad.exe; in linux, use program xedit.
A c program to call a function without using function name?
It can be done via its address, for example: void function (void (*callback)(void)) { (*callback)(); }
When a function call is made inside a running program the return address is saved on the program stack Who saves it?
The CPU (=Central Processor Unit).
