我正在编写一个程序，该程序根据给定的输入排列名称列表。这是我的代码
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_LEN 19 //names no longer than 19 chars
#define MAXPEOPLE 10
struct genderinfo {
char** winning;
char** names;
int** scores;
};
char** allocnames(int num);
int** allocratings(int num, int num2);
void inputdata(int numpeople, struct genderinfo *male, struct genderinfo *female, FILE* fp);
void permute(int permuteset[], int k, int numpeople, struct genderinfo *male, struct genderinfo *female, int *maxLindex);
void swap(int permuteset[],int i, int j);
void compare(int permuteset[], struct genderinfo *male, struct genderinfo *female, int *maxLindex, int numpeople);
///write free functions for struct arrays
int main () {
FILE* fp = fopen("matching.txt", "r");
struct genderinfo male;
struct genderinfo female;
//loop variables
int numdates, i, j, k;
//other variables
int numpeople, maxLindex = 0, difference;
fscanf(fp, "%d", &numdates);
for(i=1; i <= numdates; i++) {
fscanf(fp, "%d", &numpeople);
//printf("%d possible couples\n", numpeople);
//allocate memory for arrays of names
male.names = allocnames(numpeople);
female.names = allocnames(numpeople);
male.winning = allocnames(numpeople);
female.winning = allocnames(numpeople);
//allocate memory for score arrays
male.scores = allocratings(numpeople, numpeople);
female.scores = allocratings(numpeople, numpeople);
int permuteset[numpeople];
//fill permute set with 0-k, these will serve as array indexes to compare against malenames array
//format used will be malenames[i][permuteset[i]] femalenames[permuteset[i]][i] to index the scores
for(k=0; k<numpeople; k++)
permuteset[k] = k;
inputdata(numpeople, &male, &female, fp);
permute(permuteset, 0, numpeople, &male, &female &maxLindex);

if (k == numpeople) {
compare(permuteset, &male, &female, &maxLindex, numpeople);
}
else {
// Loop through each possible starting letter for index k,
// the first index for which we have a choice.
for (i=k; i<numpeople; i++) {
// Place the character stored in index j in location k.
swap(permuteset, k, i);
// Print out all of the permutations with that character
// just chosen above fixed.
permute(permuteset, 0, numpeople, &male, &female &maxLindex);
// Put the original character that used to be there back
// in its place.
swap(permuteset, i, k);
} //end i for
} //end else
}
void swap(int permuteset[], int i, int j) {

//This function will take a permutation in and compare malescores[i] to
//femalescores[permuteset[i]]
//if malescores[i] > femalescores[permuteset[i]] scoresum += bla blah else if.... etc.
//copy malenames[i] and femalenames[permuteset[i]] into winning couples
//with if statements above
//malescores[i][permuteset[i]]
//femalescores[permuteset[i]][i]]
void compare(int permuteset[], struct genderinfo *male, struct genderinfo *female, int *maxLindex, int numpeople) {
int temp_maxLindex, i, j, minlike;
for(i=0; i<numpeople; i++){
if (male->scores[i][permuteset[i]] > female->scores[permuteset[i]][i])
minlike = female->scores[permuteset[i]][i];
else
minlike = male->scores[permuteset[i]][i];
temp_maxLindex += minlike;
if (temp_maxLindex > maxLindex) {
maxLindex = temp_maxLindex;
for(j=0; j<numpeople; j++){
strcpy(male->winning[j], male->names[i]);
strcpy(female->winning[j], female->names[permuteset[i]]);
} //j for
} //if
} //i for
}
我收到了这些错误，其中一个与我传递给我的 inputdata 函数的内容有关，还有一堆关于冲突类型的其他错误？我现在一直在修改代码，但无处可去。在这一点上，我只是想让代码运行，这样我就可以调试算法等等，非常感谢任何帮助。
