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
