/**************************************************

** NUMBER SERIES TESTING VER 1.0

**************************************************/

#include <stdio.h>
#include <stdlib.h>

int main()
{
int first_num,sec_num,third_num,fourth_num,next_number;
int first_diff,second_diff,third_diff,fourth_diff;
printf("please enter the FOUR number after every number hit ENTER\n");
scanf("%d%d%d%d",&first_num,&sec_num,&third_num,&fourth_num);
printf("first number=%d,\nsecond number=%d,\nthird number=%d,\nfourth number=%d\n",first_num,sec_num,third_num,fourth_num);
first_diff=sec_num-first_num;
second_diff=third_num-sec_num;
third_diff=fourth_num-third_num;
if(first_diff==second_diff)
{
if(third_diff==second_diff)
{
next_number=first_diff+fourth_num;
printf("next number is ==%d\n",next_number);
}
else
{
printf("third and fourth number is not matching\n");
}
}
else{

printf("number not matching\n");
}

return 0;
}

OUTPUT:
please enter the FOUR number after every number hit ENTER
12
24
36
48
first number=12,
second number=24,
third number=36,
fourth number=48

next number is ==60

### format type in c language

#include <stdio.h>
#include <stdlib.h>

int main()
{
int a=789,b=1234;
printf("a=%3d, b=%4d", a, b);
return 0;
}

output:
a=789,b=1234

input is
a=9,b=4;
a=  9, b=   4

### "\r" carriage return in c programming language

#include <stdio.h>
#include <stdlib.h>

int main()
{
printf("Hello \rworld!\n");
return 0;
}

output :
world

because of \r in the printf statement....so after \r the statements  will be executed

### functions in python

def test():     print("good morning") test() output: good morning
