float sqroot( float x){
float a , b;
a = x; // copy given value to 'a'
do{
b = a;
a = (a + x/a)/ 2; //This equation is from Newton-Repson Method
}
while( a!= b); // execute loop until a == b
return(a); // 'a ' or 'b' is sqroot of 'x'
}

main(){
float x;
printf("Enter any number n");
scanf("%f", &x);

if( x > 0)
printf(" SQRT(%f) = %fn", sqroot( x));
else
if(x < 0)
printf(" SQRT(%f) = %fi n", sqroot( -x));
else
printf(" square root is 0 n");
getch();
