NPTEL Programming in C - Pythagorean Triples

Three numbers form a Pythagorean triple if the sum of squares of two numbers is equal to the square of the third.

 For example, 3, 5 and 4 form a Pythagorean triple, since 3*3 + 4*4 = 25 = 5*5

You are given three integers, a, b, and c. They need not be given in increasing order. If they form a Pythagorean triple, then print "yes", otherwise, print "no". Please note that the output message is in small letters.

Sample Input

3

5

4

Sample Output

yes

Note : NPTEL follows gcc compiler which doesn't supports conio.h package and it always to be started as int main() and should return a integer value

#include<stdio.h> int main() { int a,b,c,x,y,z; scanf("%d\n%d\n%d",&a,&b,&c); // Get the three values & calculate it square values x=a*a; y=b*b; z=c*c; // compare whether it satisfies Pythagorean Triples and print yes or no based on outcome if(x==y+z) printf("yes"); else if(y==x+z) printf("yes"); else if(z==x+y) printf("yes"); else printf("no"); return 0; }
