30.1 Standard Input

Write a program that accepts two variables of type int and double from the standard input. Use the fgets function to store the input into a buffer. Use the sscanf function to extract the buffer into variables:

#include <stdio.h>

int main(void)

{

      printf("Enter an int and a double and press <enter>: \n");

      char buffer[50];

      int x;

      double d;

      // read the input and store it into a buffer string

      if (fgets(buffer, 50, stdin) != NULL)

      {

            // read from a buffer string into our variables

            sscanf(buffer, "%d %lf", &x, &d); ...
