THREE IDIOTS

• Problem Description

  
  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 Dineshs mathematical skills. Binoy told Dinesh that his house is at the midpoint of the line joining Ajays house and Chandrus 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 fourth integers correspond to x2 and y2 respectively.

• CODING ARENA::

• #include <stdio.h>

  int main()

  {

    float a, b, c, d,e,f; 

    scanf("%f\t%f\n%f\t%f",&a, &b, &c, &d); 

    e=(a+c)/2;

    f=(b+d)/2;

    printf("Binoys house is located at(%.1f,%.1f)",e, f);

  
  

  return 0;

  }
