Managing Input and Output Operations

Reading of real numbers (in both decimal point and exponential notation) is illustrated in program.
#include<stdio.h>
void main()
{
      float x,y;
       double p,q;
       printf("Values of x and y:");
       scanf("%f %e", &x, &y);
       printf("\n");
       printf("x = %f\ny = %f\n\n", x, y);
       printf("Values of p and q:");
       scanf("%lf %lf", &p, &q);
       printf("\np = %lf\nq = %e",p,q);
       printf("\n\np = %.12lf\nq = %.12e", p,q);
       getch();
   }
