测试题:
0.无限个吧,因为j永远到不了10
1.10个
2.看了扩展阅读还是不懂你这题意思
3. a=14,b=5,c=9
4.
#include <stdio.h>
int main()
{
int x;
int z;
printf("请输入一个数字:\n");
scanf("%d", &x);
if(x < 0)
{
z =(0 - x);
}
else
{
z = x;
}
printf("z的值是:%d\n", z);
return 0;
}
5.
A.
if (size > 12)
{
cost = cost * 1.05;
flag = 2;
}
else

bill = cost * flag;
}
B.
if (ibex > 14)
{
goto b;
}
else
{
sheds = 3;
sheds = 2;
help = 2 * sheds;
}
C.
do
{
scanf("%d", &score);
count++;
}
while (score >= 0)
printf("count = %d\n", count);
break;
动动手:
