0：回答出10个'A'
1：一个都不会打印。
2：a = 5;
3: a == 14, b == 5, c == 9;
4: z = x > 0 ? x : -x;
5:A if (size > 12)
{
cost = cost * 1.05;
flag = 2;
}
else
{
bill = cost * flag;
}
B: if ( ibex > 14)
{
sheds = 3;
}
else
{
help = 2 * sheds;
}
C: while (score >= 0)
{
count++;
scanf("%d", &score);
}
printf("count = %d\n", count);
动动手：
0： for (years = 1; single >= compound; years++)
{
//l=p*i*n
single = 10000 + (10000 * (0.1 * years));
//s=p*(1+i)^n
compound = (10000 * pow((1 + 0.05), years));
++year;
}
printf("%d年后，黑夜的投资额超过王八蛋！\n\
王八蛋的投资额是：%.2f\n\
黑夜的投资额是：%.2f", year, single, compound);
1：
for (years = 1; total_amount > 0; years++)
{
total_amount = total_amount - 500000;
total_amount = (total_amount * 0.08) + total_amount;
if (total_amount <= 500000)
{
total_amount = total_amount - total_amount;
}
}
printf("%d年之后，会小王八^_^会败光所有家产，再次一穷二白。", years);

92736 初项是2 2的fib嘛
#include <stdio.h>
#include <math.h>
void main(){
int a1 = 2, a2=2, limit = 24, temp;
// n1=2, n2=2, n3=n2+n1=4, n4=n3+n2=6, n5=n4+n3=10;
for(int i=3;i<=limit;i++){
temp = a2;
a2 = a1+a2;
a1 = temp;
}
printf("sum=%d",a2);
}
啊是‘对‘ 结果除以2就行了 46368
