Program to demonstrate example of static function in C language#include <stdio.h> //static function definition static long int getSquare(int num){ return (num*num); } int main() { int num; printf("Enter an integer number: "); scanf("%d",&num); printf("Square of %d is %ld.\n",...
Well, there is a hidden problem in the code. More specifically, its the return value of the function ‘func_Str()’. The value being returned is the address of the local pointer variable ‘p’. Since ‘p’ is local to the function so as soon as the function returns, the lifetime of...
A static variable inside a function keeps its value between invocations. In the C programming language, static is used with global variables and functions to set their scope to the containing file. In local variables, static is used to store the variable in the statically allocated memory instead...
Now, we start the main() function so that we can call the previously-defined functions and get the desired output. We create three instances of the “static_class” class named a, b, and c in the main() method. Using the static_class::instanceCount += 3, we then increase the instan...

http://stackoverflow.com/questions/572547/what-does-static-mean-in-a-c-program Static could be used for (1) variable and (2) function. A static variable inside a function keeps its value between invocations.(functions call). A static global variable or a function is "seen" only in the ...
Astaticclass is basically the same as a non-static class, but there's one difference: a static class can't be instantiated. In other words, you can't use thenewoperator to create a variable of the class type. Because there's no instance variable, you access the me...
also discussed how to declare the variable globally and how to write the function outside the main() body, and then how to callback the function through different examples. I hope that this tutorial will be beneficial to you as you learn about static variables in the C programming language....
