尝试用 C 语言编译程序时出现一些警告:
13:20: warning: excess elements in array initializer [enabled by default] 13:20: warning: (near initialization for ‘litera’) [enabled by default] 22:18: warning: excess elements in array initializer [enabled by default] 22:18: warning: (near initialization for ‘liczba’) [enabled by default] 43:1: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘int’ [-Wformat] 45:2: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘int’ [-Wformat] 55:2: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘int’ [-Wformat]
来源是:
char litera[63] = {'E', 'G', 'H', 'F', 'E', 'G', 'H', 'F',

int liczba[63] ={'8', '7', '5', '6', '4', '3', '1', '2',
'1', '2', '4', '3', '5', '6', '8', '7',
'5', '7', '8', '6', '4', '3', '1', '2',

/*line22*/ '2', '4', '3', '5', '6', '8', '7', '5'};
int i=0, x=0, n;
char a;
int b=0;
printf("Podaj literę z pola startowego skoczka(duże litery)\n");
scanf("%s", &a);
printf("Podaj liczbę z pola startowego skoczka \n");
scanf("%d", &b);
if (b<=0 || b>8){
printf("Zła pozycja skoczka\n");
return 0;
}
while (litera[i] != a || liczba[i] != b){
++i;
}
n=i;
/*line43*/ printf("Trasa skoczka od punktu %s %d to:\n", a, b);
while (i<=64){
/*line45*/ printf("%s%d ", litera[i], liczba[i]);
++i;
++x;
x=x%8;
if(x==0)
printf("/n");
}
i=0;
while (i<n){
/*line55*/ printf("%s%d ", litera[i], liczba[i]);
++i;
++x;
x=x%8;
if(x==0)
printf("/n");
}
我也有“核心转储”之后scanf("%d", &b);
,但int b=0;
没有问题......
