Integer : int

integer are whole numbers with negative

default int without declaring space ranges from:

$-2^{31} ~~ to ~~ 2^{31}$

To use a variable we have to declare it first:

To assign a value into integer:

int integer;

	integer = 10;

declare and assign at the same time:

int integer = 10;

to print out variables:

	printf("%d", integer);

%d is used in string for integer

Sample code:

#include <stdio.h>

int main(){
	int integer;
	integer = 10;
	
	printf("%d", integer);
		
	return 0;
}
