*我没有写代码。该代码已包含在问题中。
#include <stdio.h>
#include <math.h>
int main()
{
int a[7]={2,0,0,0,0,0,0};
int i=1;
for (i=1; i<7; i++)
{
if (i<3)
a[i] = a[i-1]+i+1; //when i=1, a[1]= a[1-1]+1+1 -> a[0]+1+1 -> 2+1+1=4
//a[1] is now 4
//when i=2, a[2]= a[2-1]+1+1 -> a[1]+1+1 -> 4+2+1=7
//a[2] is now 7
else if (i<5)
a[i] = a[i-2]+1; //when i=3, a[3]= a[3-2]+1 -> a[1]+1 -> 4+1=6
//a[3] is now 6 but it should be 11??? 11
//when i=4, a[4]= a[4-1]+1 -> a[2]+1 -> 7+1=8
//a[4] is now 8 but it should be 16??? 16
else
a[i] = a[i-2]*i-2; //when i=5, a[5]= a[5-2]*5-2 -> a[3]*3 -> 6*3= 18
//a[5] is now 18 but it should be 22???
//when i=6, a[6]= a[6-1]*6-2 -> a[5]*4 -> 18*4= 72
//a[6] is now 8 but it should be 29????
}
for (i=0; i<7; i++)
printf("a[%d] = %d\n",i,a[i]); //prints a[0] = 2 first because i=0 in the above loop
}
实际输出:
a[0] = 2
a[1] = 4
a[2] = 7
a[3] = 11
a[4] = 16
a[5] = 22
a[6] = 29
答案 0 :(得分:1)
我复制了您的代码并运行了,这是我的输出:
a[0] = 2
a[1] = 4
a[2] = 7
a[3] = 5
a[4] = 8
a[5] = 23
a[6] = 46
