Question

dev c++ 程序运行就提示停止工作

源代码：#include <stdio.h>
int judge(char,char,char);
main()
{
char a,b,c;
printf("Please input three char:");
scanf("%c %c %c",&a,&b,&c);
if ((a>=65)&&(a<=90)&&(b>=65)&&(b<=90)&&(c>=65)&&(c<=90)&&(a>=97)&&(a<=122)&&(b>=97)&&(b<=122)&&(c>=97)&&(c<=122))
{if (judge(a,b,c))
{printf("The letters are adjacent with each other");}
else
{printf("The letters are not adjacent with each other");}
}
else
{printf("The letters are not adjacent with each other");}
}
int judge(char x,char y,char z)
{
if(((y-x)==1)&&((y-z)==1))
return 1;
else
return 0;

}

可以看到“Please input 。。。”的输出，输完之后就停止工作了。。

Answer 1

main函数前加一个类型说明符 试一下
int main()
{
//
}
