Ajay, Binoy and Chandru were very close friends at school. They were very good in Mathematics and they were the pet students of Emily Mam. Their gang was known as 3-idiots. Ajay, Binoy and Chandru live in the same locality.

A new student Dinesh joins their class and he wanted to be friends with them. He asked Binoy about his house address. Binoy wanted to test Dinesh's mathematical skills. Binoy told Dinesh that his house is at the midpoint of the line joining Ajay's house and Chandru's house. Dinesh was puzzled. Can you help Dinesh out?

Given the coordinates of the 2 end points of a line (x1,y1) and (x2,y2), write a C program to find the midpoint of the line.
 

Input Format:

Input consists of 4 integers. The first integer corresponds to x1 . The second integer corresponds to y1. The third and fouth integers correspond to x2 and y2 respectively.

Dinesh also joined the group of 3 idiots and now their group is called Four Seasoners. Meanwhile, Binoy has moved to a new house in the same locality. Now the houses of Ajay, Binoy and Chandru are in the located in the shape of a triangle. Dinesh also has moved to a house in the same locality. When Ajay asked Dinesh about the location of his house , Dinesh said that his house is equidistant from the houses of the other 3. Though Ajay was good in Mathematics, he was puzzled. Can you please help Ajay out?

Raju lives in a colony. On his 9th birthday, his father gifts him a Pogo Stick, Raju is so excited to play with the pogo stick. The pogo stick moves one unit per jump. He wanders around his house jumping with pogo sticks. He likes to show the pogo stick to his friends and decides to go using the pogo sticks. Write a program to find the number of jumps needed to reach his friend's house. Assume that Raju's house is in the location (3,4).

Input and Output Format:
Input consists of two integers x,y. The x and y corresponds to x and y coordinates of his friend's house.
Output is an integer - the number of jumps he needs to reach his friend's house.

Sample Input and Output:
Enter the X and Y coordinate of the friend's house

                                                               INTERCEPTS

Emily is a very popular Maths Teacher in School. She retires from her service today. Her 7th class students like her very much and they wanted to give her a grand farewell at school. The school HeadMistress is a very strict person and she didn't give permission for them to conduct the farewell in the school premises. The students decided to conduct the farewell at Emily Mam's house itself.
 

They know the street in which Emily mam lives. The student leader asked Emily Mam to tell her house number. Emily Mam's last class was on Equation for a straight line. She said that a straight line can be represented by the equation y=mx+c and you know how to find the x-intercept and y-intercept of the line and my house number is the sum of the x-intercept and y-intercept of the line.
 

The students were puzzled. Can you help the students find the house number of Emily Mam?

Given the values of m and c of the line equation y=mx+c, write a C program to find the sum of x-intercept and y-intercept.

Input Format:

Input consists of 2 integers. The first integer corresponds to m and the second integer corresponds to c.

Output Format:

Refer Sample Input and Output for exact formatting specifications.

[Assume that the inputs are such that the intercept values are always integers]

Sample Input and Output:

[All text in bold corresponds to input and the rest corresponds to output]

Value of m:

5

Value of c:

10

The line equation is y=5x+10

x intercept is -2

y intercept is 10

The house number is 8

SOLUTION :

Your Submission is correct.

#include<stdio.h>

int main()

{

int m,c,x,y;

printf("Value of m:\n");

scanf("%d",&m);

printf("Value of c:\n");

scanf("%d",&c);

printf("The line equation is y=%dx+%d\n",m,c);

x=-c/m;

printf("x intercept is %d\n",x);

y=c;

printf("y intercept is %d\n",y);

printf("The house number is %d",x+y);

return 0;
