Display of structures is sorted with the highest score listed first.

Demo

#include <stdio.h>

int main()/*from   w  w w  .  java  2s  . co  m*/
{
    struct scores
    {
        char name[32];
        int score;
    };
    struct scores player[4];
    struct scores temp;
    int x,a,b;

    for(x=0;x<4;x++)
    {
        printf("Enter player %d: ",x+1);
        scanf("%s",player[x].name);
        printf("Enter their score: ");
        scanf("%d",&player[x].score);
    }

    for(a=0;a<4;a++)
        for(b=a+1;b<4;b++)
            if(player[a].score<player[b].score)
            {
                temp=player[a];
                player[a]=player[b];
                player[b]=temp;
            }

    puts("Player Info");
    printf("#\tName\tScore\n");
    for(x=0;x<4;x++)
    {
        printf("%d\t%s\t%5d\n",
            x+1,player[x].name,player[x].score);
    }
    return(0);
}
