用C语言编写一个排列组合的程序

#include<stdio.h>

int a[5]

int len1,len2,len3

void input(int len1,int len2,int len3)

{

printf("%d %d %d\n",a[len1],a[len2],a[len3])

}

void solve(int len1,int len2,int len3)

{

input(len1,len2,len3)

if(len1==2) return

if(len3<4) len3++

else if(len2<3)

{

len2++

len3=len2+1

}

else if(len1<2)

{

len1++

len2=len1+1

len3=len2+1

}

solve(len1,len2,len3)

}

void main()

{

int i

for(i=0i<和汪5i++) a[i]=i+1

printf("嫌汪所构芹棚仔成组合是:\n")

solve(0,1,2)

return

}

CTestPermutation::~CTestPermutation()

{

cout<<">>竖亏旅>>>空磨>>>>>>>>>>>>>>>>>>>CTestPermutation::~CTestPermutation()"<<endl

}

void CTestPermutation::DoTest()

{

cout<<"-------将余凳N个数进行排列组合-------"<<endl<<endl

vector<int>vecNums,vecPermutated

cout<<"示例数据:"

for(int i = 1i <5i++)

{

vecNums.push_back(i)

cout<<i<<" "

}

cout<<endl

cout<<"排列组合结果："<<endl

Permutation(vecPermutated,vecNums)

}
