不知道为啥截不了图了。只能上代码了。

#include<stdio.h>
#define N 8
typedef struct
{
    int n;
    int row;
    int line;
}AnswerType;
AnswerType answer[N];
typedef enum
{
    notoccued = 0,
    occued = 1
}Ifoccued;
Ifoccued RowOccued[N];
Ifoccued LeftTop_RightDown[2*N-1];
Ifoccued LeftDown_RightTop[2*N-1];
void print();
int num;
void start(int LineIndex)
{
    for(int RowIndex=0;RowIndex<8;RowIndex++)
    {
        if(RowOccued[RowIndex]==notoccued&&LeftTop_RightDown[RowIndex-LineIndex+N-1]==notoccued
            &&LeftDown_RightTop[RowIndex+LineIndex]==notoccued)
        {
            RowOccued[RowIndex]=occued;
            LeftTop_RightDown[RowIndex-LineIndex+N-1]=occued;
            LeftDown_RightTop[RowIndex+LineIndex]=occued;
            answer[LineIndex].row=RowIndex;
            answer[LineIndex].line=LineIndex;
            if(LineIndex==7)
            { 
                num++;
                answer[0].n++;
                print();
                RowOccued[N]=notoccued;
                LeftTop_RightDown[2*N-1]=notoccued;
                LeftDown_RightTop[2*N-1]=notoccued;
            }else
            {
                start(LineIndex+1);
            }
        RowOccued[RowIndex]=notoccued;
        LeftTop_RightDown[RowIndex-LineIndex+N-1]=notoccued;
        LeftDown_RightTop[RowIndex+LineIndex]=notoccued;
        }
    }
}
void print()
{
    printf("第%d个结果为：",num);
    for(int i=0;i<N;i++)
    {
        printf("[%d,%d] ",answer[i].line+1,answer[i].row+1);
    }
    printf("\n");
}
int main()
{
    num=0;
    answer[0].n=0;
    start(0);
    return 0;
}

注意倒数第14行的printf("第%d个结果为：",num);   根据我的设想应该是输出第1个结果为...一直到输出第92个结果为
但实际是输出了92个第一个结果为

然后我将整形计数器num换成了answer结构体中的变量n，代码如下

#include<stdio.h>
#define N 8
typedef struct
{
    int n;
    int row;
    int line;
}AnswerType;
AnswerType answer[N];
typedef enum
{
    notoccued = 0,
    occued = 1
}Ifoccued;
Ifoccued RowOccued[N];
Ifoccued LeftTop_RightDown[2*N-1];
Ifoccued LeftDown_RightTop[2*N-1];
void print();
int num;
void start(int LineIndex)
{
    for(int RowIndex=0;RowIndex<8;RowIndex++)
    {
        if(RowOccued[RowIndex]==notoccued&&LeftTop_RightDown[RowIndex-LineIndex+N-1]==notoccued
            &&LeftDown_RightTop[RowIndex+LineIndex]==notoccued)
        {
            RowOccued[RowIndex]=occued;
            LeftTop_RightDown[RowIndex-LineIndex+N-1]=occued;
            LeftDown_RightTop[RowIndex+LineIndex]=occued;
            answer[LineIndex].row=RowIndex;
            answer[LineIndex].line=LineIndex;
            if(LineIndex==7)
            { 
                num++;
                answer[0].n++;
                print();
                RowOccued[N]=notoccued;
                LeftTop_RightDown[2*N-1]=notoccued;
                LeftDown_RightTop[2*N-1]=notoccued;
            }else
            {
                start(LineIndex+1);
            }
        RowOccued[RowIndex]=notoccued;
        LeftTop_RightDown[RowIndex-LineIndex+N-1]=notoccued;
        LeftDown_RightTop[RowIndex+LineIndex]=notoccued;
        }
    }
}
void print()
{
    printf("第%d个结果为：",answer[0].n);
    for(int i=0;i<N;i++)
    {
        printf("[%d,%d] ",answer[i].line+1,answer[i].row+1);
    }
    printf("\n");
}
int main()
{
    num=0;
    answer[0].n=0;
    start(0);
    return 0;
}

与第一段代码唯一不同之处就是把倒数第14行改成printf("第%d个结果为：",answer[0].n);
输出就对了 是从1到92
我不明白为什么第一段代码结果输出的全是1
求解！谢谢！

表示确实一样，都是1-92，楼主准备换编译器吧

吧num初始化试一试呢？
不初始化总有可能得到很奇葩的结果
