#include<stdio.h>
int main()
{
int a=2,b=3,c=5,sum;
sum=a+b+c;
printf("the num 2,3,5");
printf("\nthe sum of these three num is:%d",sum);
return 0;
}

OUTPUT FOR ABOVE PROGRAM:

	output 1:the num 2,3,5
	the sum of these three num is:10

SUM AND DIFF. OF TWO NUMBERS(PROGRAM 2)

#include<stdio.h>
int main()
{
int a=3,b=2,sum,diff;
sum=a+b;
diff=a-b;
printf("the sum of these 3,2  is:%d",sum);
printf("\n\nthe diff of these 3,2 is:%d",diff);
return 0;
}

output FOR ABOVE PROGRAM:

	the sum of these 3,2  is:5
	the diff of these 3,2 is:1 
output:
	the num 2,3,5the sum of these three num is:10

return 0;
}

arithmatic operators(PROGRAM 4)

#include <stdio.h>
main() 
{
 int a = 21;
 int b = 10;
 int c ;
 c = a + b;
 printf("Line 1 - Value of c is %d\n", c );
 c = a - b;
     printf("Line 2 - Value of c is %d\n", c );
 c = a * b;
printf("Line 3 - Value of c is %d\n", c );
c = a / b;
printf("Line 4 - Value of c is %d\n", c );
return 0;
}

TOTAL AND AVERAGE OF 6 SUBJECTS(PROGRAM 5)

#include <stdio.h>

	total=tamil+english+maths+physics+chemistry+computer_science;
		avg=(float)total/5;
		printf("the total marks subject tamil,english,maths,physics,chemistry,computer_science is: %d",total);
	printf("\nthe total average is :%2.f",avg);
		return 0;
	}

OUTPUT FOR ABOVE PROGRAM

 return 0;
 } 

//NOTE: (PRE) MEANS CHANGE FROM THE NEXT STEP WHEATHER INCREASE OR DECREASE NOT FROM THAT STEP
