I need someone to fix my code to solve exactly what the problem asks to. My code does not solve it correctly.

Write a function that computes the square root of a number. The square root of a number x can be approximately computed as follows. First guess that the square root of xis1. Then repeatedly get the next guess from the last guess using the rulenext= 0.5(last+ x/last) where last is the last guess and next is the next guess. Repeat ten times using a loop and the tenth guess will be approximately the square root. The function prototype is double compute_sqrt(double x). The function computes the square root of x and returns the square root.

This is my code.

double compute_sqrt(double x) {

// 2. This function computes the square root of a number.

int i;

double next;

double last=1;

// loop 10 times

for(i=1;i<=10;i++) {

//next guess

next=0.5 *(last + x/last);

//assign the new guess to last

last=next;

}

//return last guess

return last;

}

int main(){

while(n!=1) {

double n;

double k;

//enter an number

printf("Enter a positive integer: ");

scanf("%lf", &n);

//call to the compute_sqrt function

k= compute_sqrt(n);

//diplay

printf("Square root is %lf ", k);

}

printf(" Exiting program. ");

break;

}
