Solution for Exercise 12-4

ex1204

#include <stdio.h>

int main()
{
    int highscore[4];
    int x;

    for(x=0;x<4;x++)
    {
        printf("Your #%d score: ",x+1);
        scanf("%d",&highscore[x]);
    }

    puts("Here are your high scores");
    for(x=0;x<4;x++)
        printf("#%d %d\n",x+1,highscore[x]);

    return(0);
}

Notes

* The x+1 trick doesn't change the value of x, which is used in the loops as well as to reference each array element. No, that equation allows a human number to be displayed. You'll use that trick often when you plow through arrays.

* The & operator is still required by scanf() to read values into an array element. Each array element is essentially an individual variable. The & operator doesn't really care whether the variable is part of an array or floating off in memory somewhere.
