beginn:
#include <stdio.h>
#include <stdlib.h>
those you need to open the library and the in and output
void main()
to starts the main application
Variable tybes:
integers(int) :single numbers withotu decimals (1,2,3,4,5,.......)
characters(char) :single letters (a,b,c,d,......)
floating numbers(float) :numbers with decimals (1.2 ;4.3 ;5.6 ;......)
string(string) :array of charracters (abcd; djhkhk;......)
printing on screen:
to tell the program to print something on the screen you have to write the the word : printf (" enter text here ")
to print an variable use %i for example printf(" your first number is equal to %i" ) to tell the program what the variable is write the variable you want to you use behind the the "

arrays
a array of characters for example int numbers[10]; which means that it edited ten of this characters
Loops:
while:
the program which is written in the brakkets will be repeated as long as the answer is right.
for :

end
to end the you have to write while(1); to finish (only in class, this isn't need in the real world ever never)
