Getting multiple values with scanf()

Yes.

int minx, miny, maxx,maxy;
do {
   printf("enter four integers: ");
} while (scanf("%d %d %d %d", &minx, &miny, &maxx, &maxy)!=4);

The loop is just to demonstrate that scanf returns the number of fields succesfully read (or EOF).


You can do this with a single call, like so:

scanf( "%i %i %i %i", &minx, &maxx, &miny, &maxy);

Just to add, we can use array as well:

int i, array[4];
printf("Enter Four Ints: ");
for(i=0; i<4; i++) {
    scanf("%d", &array[i]);
}

int a,b,c,d;
if(scanf("%d %d %d %d",&a,&b,&c,&d) == 4) {
   //read the 4 integers
} else {
   puts("Error. Please supply 4 integers");
}
