Call by value and Call by Reference  in C ->Watch this for FUN -  Funny job interview Are you getting bored with online lectures? ->Watch this -  When online lectures are boring   There are two ways to call out a function in C and those are Call by Value and Call by Reference. So, what they are, let's find out. <><><><><><><> Call by value :                                 Here the values in the function get copies of the original values but they don't get a revert to the modified value.  For example:                      void swap(int x, int y)                      {                             int temp=x;                             x=y;                             y=temp;                      }                      int main()                     {                      int a=5,b=7;                      swap(a,b);                      printf("%d %d\n",a,b);// Would print 5 7 although the values got modified in the funct

Making your header file ->Watch this for FUN -  Funny job interview Are you getting bored with online lectures? ->Watch this -  When online lectures are boring   Yes, you can make your header file, as we use the standard header files which are stored in your system, the same way we can also make our. So, let's see how? Step 1 . Define the functions which you will gonna use in the program in some file named (hello.h). Step 2 . In the program file, use #include"hello.h" for including that header file which has been saved by you. <><><><><><><> That's it, you are done, now you can use the functions which you have declared in the hello.h file anywhere in the program.

Standard header files in C programming language ->Watch this for FUN -  Funny job interview Are you getting bored with online lectures? ->Watch this -  When online lectures are boring   Header files are the files that contain the set of predefined library functions that can be used anywhere while writing the program. That's why they become handy in use for their operations while writing a C program. Even you can make your header file. The following header files are the standard ones: 1. stdio.h                This header file is used for various input/output functions like printf() , scanf() ,etc. <><><><><><><> 2. stdlib.h                This header file is mainly used for dynamic memory allocation like malloc() , calloc() , realloc() , free() and even for some functions like abs() [for absolute value of the number] and atoi() [ for converting string to a number] and even more. <><><><><><><&g

5th Generation ->Watch this for FUN -  Funny job interview Are you getting bored with online lectures? ->Watch this -  When online lectures are boring   What is 5G?                     It is the technology that is the 5th generation standard for cellular networks. With the increasing demands and connectivity between people, 5th generation technology is a game-changer for them. It would lead to serving a million devices per square kilometer while the existing one 4G serves 100,000 devices per square kilometer. So you can now estimate its impact on people's lives. With GLOBAL data traffic doubling every 18 months, high-speed 5G connectivity comes into play. This technology would reduce human digital tasks in a second. <><><><><><><> <><><><><><><> Working of 5G:                          The service area of its reach would get divided into small geographical locations called cells. Hence all 5G w
