Hello there I am Achyuta, today we are talking about C programing language. This is the first part of c.
What should we learn?
- Preprosser Directive of C.
- Data types of C.
Let’s start…
C, c is the basic programing language.This is a example of c program. Create a file ending with .c that will be your c file.
Example 1:

# include <stdio.h>
int main(int argc, char const *argv[])
{
int c=100;
int m=0;
while (c>=m){
printf("%d\n",m);
m++;
}
}
Copy the example above and run it from the instructions given below.
- Run this command
cc (your_file_name).c. - Run
./a.out.
If you are in any editor you can follow these instructions or find how to run it that should be easy!
Preprosser Directive of C
Preprosser Directive of C is

# include <stdio.h>
main()
{
// your code
}
Explanation
# include <stdio.h> :
# include includes the given library in <>.You can include infinite librarys.But one after one.
stdio.h is a library of c.The full form is standrd input output.
main() is a starting point of your program.It is a function we talk about more on functionns in other blogs.
The code in {} is executed.
Printing
Printing in c is a bit different than other languages like Python.
Text and numbers can be printed easily by printf
Data types of C
Char
Every Char can hold a character. Char is defined by the keyword char.
The char type is printed by using %c in the printf function. Example 2:

{
int c=100;
int m=0;
while (c>=m){
printf("%d\n",m);
m++;
}your
// code
}
