printf("Enter a number :");
scanf("%d",&number);
temp = sqrt(number);
printf("\n%d",sqrt(number)); //print 987388755 -- > wrong result

return 0;

and in this code there are a result for input value 10 is

987388755

Answer 1

sqrt returns a double:

double sqrt(double x);

You need:

printf("\n%g",sqrt(number));
