Write a program that calls a function to scale a real number x into its scientific notation so that 1 lessthanorequalto x lessthanorequalto 10. The amount that x is shifted should be stored into the second argument. Each argument is pass-by-reference. The following function prototype is required. void sci_notation(double *x, int *n); Here is an example of when n would be negative Enter number: 2459.1 x: 2.459 n: -3 Here is an example of when n would be positive Enter number: 0.0002591 x: 2.591 n: 4

Solution

#include \"stdio.h\"

void sci_notation(double *x,int *n){
   while(*x>10){               // while number greater than 10.
       *x = *x / 10;           // divide by 10.
       *n = *n-1;
   }
   while(*x<=1){           // while number less than 1.
       *x = *x * 10;       // multiply by 10.
       *n = *n+1;
   }
   return;
}

int main(void) {
   double x;
   int n = 0;
   printf(\"Enter number:\");
   scanf(\"%lf\",&x);
   sci_notation(&x,&n);               // call the function.
printf(\"x:%f\ n:%d\ \",x,n);
return 0;
}
