Get size and address for a double
#include<stdio.h>
int main(void)
{
double d = 4.0;
double e = 5.0;
double f = 6.0;
printf("\n\nA variable of type double occupies %d bytes.", sizeof(double));
printf("\nHere are the addresses of some variables of type double:");
printf("\nThe address of d is: %p The address of e is: %p", &d, &e);
printf("\nThe address of f is: %p\n", &f);
return 0;
}A variable of type double occupies 8 bytes.
Here are the addresses of some variables of type double:
The address of d is: 9a378 The address of e is: 9a370
The address of f is: 9a368
Use sscanf to get and then double a number from the user
#include <stdio.h>
int main()
{
char line[100];
int value;
printf("Enter a value: ");
fgets(line, sizeof(line), stdin);
sscanf(line, "%d", &value);
printf("Twice %d is %d\n", value, value * 2);
return (0);
}Enter a value: 123
Twice 123 is 246
