Three positive integer numbers a, band c, such that a<b<c form a Pythagorean triplet if c^{2}= a^{2} +b^{2} , i. e,, a, b and c form the sides of a right-angled triangle. To select the values of a and b such that a < b and a, b < max, we can use nested for loops as shown below:
Note the use of typecast in the if statement to test whether c contains an integer value or not and in the printf statement. The complete program is given below.
/* Determine and print Pythagorean triplets */
#include <stdio.h>
#include <math.h>
void main()
{
int max; /* max value of side a or b */
int a, b; /* two sides of a triangle */
clrscr();
printf("Enter max value of sides a, b: ");
scanf("%d", &max);
for (a = 1; a <= max; a++)
{
for (b = a; b <= max; b++)
{
float c = sqrt(a *a+ b * b); /*third side*/
if (c == (int) c)
printf ("%2d %2d %2d\n", a, b, (int) c);
}
}
getch();
