iostram.h error when compiling a C code

I want to compile this code with GCC, using terminal :
#include <iostream.h>
#include <stdlib.h>
int main()
{
char card_name[3];
puts("Enter the card_name:");
scanf("%2s", card_name);
int val = 0;
if (card_name[0] == 'K') {
val = 10;
} else if (card_name[0] == 'Q') {
val = 10;
} else if (card_name[0] == 'J') {
val = 10;
} else if (card_name[0] == 'A') {
val = 11;
} else {
val = atoi(card_name);
}
printf("The card value is : %i\n", val);
return 0;
}
But I got an error : fatal error: iostream.h: No such file or directory
What is the problem ? Please explain complete .
