C Programming - 4.5 The printf() function

We have been talking about this guy for so long and he finally came

And you will see him most of the time whenever you write a C code.

So,
What printf() function do?
It basically prints everything within the double quotation.

for example:

printf("I am a programmer");

this prints:   
                I am a Programmer

In full code that will be-

#include <stdio.h>

int main()
{

     printf("I am a Programmer");

     return 0;
}

Now, see another code 

#include <stdio.h>

int main()
{

     printf("I am a Programmer");
     printf("I am a Programmer");

     return 0;
}

the output will be:

         I am a ProgrammerI am a Programmer
The output is like this because we haven't use newline character to indicate the end of the line. So, the correction of the code will be:

              printf("I am a Programmer\n");
              printf("I am a Programmer");

that will do the desired output:
                                                      I am a Programmer
                                                   I am a Programmer


but if we insert a third line saying printf("I am a Programmer"); then it will show the same problem. So, I prefer to write

               printf("I am a Programmer\n");
               printf("I am a Programmer\n");

but it depends upon the problem requirement what we want in the output


Now look  at this code

#include <stdio.h>

int main()
{

     printf("I am a Programmer\n");
     printf("\tI am a Programmer\n");
     printf("\t\tI am a Programmer\n");

     return 0;
}

Output:

         I am a Programmer
                   I am a Programmer
                             I am a programmer



look carefully at the code, you will find newline characters and TAB characters within printf() and they are responsible for this cool output.

Now play with it

C Programming - 4.1 First C program

First C program #include <stdio.h> int main() {      printf("I am a Programmer\n");      return 0; } Output:                    I am a Programmer In the next tutorials, we will understand this code point by point. Semicolon Issue we have to remember one important thing always end of every statement in C we have to put a semicolon From the first code, there are two statements        printf("I am a Programmer\n");        return 0; and both of them have a semicolon at the end of the line or statement Some people find this annoying 😒 but like it or  not we have to be careful about this Happy Coding See you in next tutorial Next Post: https://coderavens.blogspot.com/2018/05/c-programming-42-main-function.html

C Programming - 4.3 Header Files

Now, again see the first C program I wrote #include <stdio.h> int main() {      printf("I am a Programmer\n");      return 0; } Now, what #include <stdio.h> means actually  Here, stdio.h known as a Header file 😮, remember it's not studio.h 😜 . So many persons done that mistake when he/she first write C codes And, the coolest thing about header file is, it will give you a headache 😨 OK, I am just kidding  Header file term refers to that kind of file which contains C function declarations and macro definitions. A C header file contains .h extension. Like in this code stdio.h contains function declaration and definition of printf() that's why we had to include the  stdio.h  header file at the top of the code The basic syntax of including header files on top of the code #include <header_file_name> Now, you can wonder about printf() function, don't worry we will lea...

C Programming - 4.2 The main() function

The main() function is the entry 🔑 point of a C program Now look at the code what I wrote #include <stdio.h> int main() {      printf("I am a Programmer\n");      return 0; } OK, I wrote, int main() here "int" represents the Integer number is, an Integer number is a whole number not a fraction one like 1,2,0,10,55 etc. now, the question ❓ is- Why I wrote int main() We all know mathematical function right. for example :                         f(x) = bx+c this function  f(x)  has a return value, let's say it's Integer , then for C it is int C functions are quite similar to mathematical functions , the basic format of a C function is return_type function_name() { } by writing int main(), we indicate that this main() function will return an int number. that's ...
