先驱1
# include stdio . h
# include math.h
int main()
{
双a、b;
scanf(“%低频”等);
如果( 0)
printf(“数量错误!”);
其他的
{ b = sqrt(a);
printf( % f”,b);
}
返回0;
}
先驱2
# include stdio . h
# include math.h
int main()
{
双x,y;
scanf(“%低频”,x);
如果(x = 0 x = 8)
{ y = x + 2 *战俘(x,2)+ 10;
printf( % f”,y);}
其他{ y = 3 *战俘(x,3)9;
printf( % f”,y);}
返回0;
}
P94 4
# include stdio . h
# include math.h
int main()
{
双a,b,c
scanf(“%低频%低频”等,福利);
如果( = 0,b = 0)c =战俘(a,2)+战俘(b,2);
else if(b 0, 0)c =战俘(a,2)战俘(b,2);
else if(b = 0, 0)c = a + b;
else if(b 0 = 0)c = a - b;
printf( % f、c);
返回0;
}
判断输入字符
# include stdio . h
int main()
{
字符;
scanf(“% c”等);
如果( 47个 58)printf(数字”);
else if(一个 64 64)printf(大写字母”);
else if(一个 96 96)printf(小写字母”);
elseprintf(“其他符号”);
返回0;
}
判断闰年
# include stdio . h
int main()
{
int x;
scanf(“% d”,x);
if(x % 4 = = 0 x % 400 = = 0)printf(是闰年”);
else if(x % 4 = = 0 x % 100 ! = 0)printf(是闰年”);
其他printf(不是闰年”);
返回0;
}
# include stdio . h
int main()
{
int x;
scanf(“% d”,x);
if(x % 4 = = 0 x % 400 = = 0){ printf( % d”,x);printf(是闰年”);}
else if(x % 4 = = 0 x % 100 ! = 0){ printf( % d”,x);printf(是闰年”);}
其他{ printf( % d”,x);printf(不是闰年”);}
返回0;
}
P94-9
# include stdio . h
# include math.h
int main()
{
int a、b;
scanf(“% d”等);
b = 0;
虽然( 0)
{ b = b + 10(%);
一个= 10 /;
}
printf( % d”,b);
返回0;
}
好的

(= 100,e = 100,b = 0,c = 0,d = 0; 1000;+ +)
{
b = % 10;a = 10 /;c = % 10;一个= 10 /;d = % 10;
如果(e = =战俘(b,3)+战俘(c,3)+战俘(d,3)printf( % 5 d,e)
其他的;
}
}
P94-15
# include stdio . h
