Have an error! Could someone pls? && Does it really need of fabs ().

Question

#include <stdio.h>

int main()
float true_val,approx_val;
float ea,er,ep;

//input: Enter true value & approximate value
//scanf("%f",&true_val);

//input: Enter approximate value
//scanf("%f",&approx_val);

scanf("%f%f",&true_val&approx_val);
ea=fabs(true_val - approxx_val );
er=ea/true_val;
ep=er*100;
printf("\n Absolute Error is : ",ea);
printf("\n Relative Error is : ",er);
printf("\n Precentage Error is : ",ep);
return 0;
}

Answer 1

{ missing after int main ()
Line 14: separate &true_val and &approx_val with a comma
Line 15: use same spelling for your variables all the way through
Line 18-20: format specifiers missing (%.2f etc.)

Answer 2

missing math.h include in addition of errors mentioned by Anna

Answer 4

if I run this program after debugging, it only ask for input once. But it should ask twice coz there are two inputs required.
