Small application of C language using structure to simulate election

C Small application of simulated election of language structure

• Now there are three candidates , Five voters
• In the end, the higher one wins

Used in small applications C The structure in the language is the main writing body
Code up

#include <stdio.h>
#include <string.h>

struct XuanMin
{
    
	char name[32];
	int tickets;
};

int main()
{
    
	struct XuanMin xm[3];
	struct XuanMin max;
	struct XuanMin max1;
	
	int feiPiao = 0;
	int i;
	int len;
	int j;
	int mark = 0;
	
	int total = 5;
	char tmpName[32];
	
	// Initialize voter information 
	len = sizeof(xm)/sizeof(xm[0]);
	for(i = 0; i<len; i++){
    
		xm[i].tickets = 0;
		printf(" Please enter the first %d The name of a voter ：\n",i+1);
		scanf("%s",xm[i].name);
	}
	// Ticket singing 
	for(i=0;i<5;i++){
    
		
		mark = 0;
		printf(" Please enter who you vote for ：\n");
		memset(tmpName,'\0',sizeof(tmpName)); // Empty it every time 
		scanf("%s",tmpName);// Enter the name of the selected voter , Like opening a ballot , See the same name 
		for(j = 0;j<len; j++){
     // Get the name , The number of votes of the corresponding candidate plus 1
			if(strcmp(tmpName, xm[j].name) == 0){
    
				xm[j].tickets++;
				mark  = 1;
			}
		}
		if(mark == 0){
    
			printf(" There is no such candidate , give up \n");
			feiPiao++;
		}
	}
	// Publish the results 
	for(i=0;i<len;i++){
    
		printf(" name ：%s, Number of votes ：%d\n",xm[i].name,xm[i].tickets);
	}
	max = xm[0];
	max1 = xm[0];
	for(i=1;i<len;i++){
    
		if(max.tickets < xm[i].tickets)
		{
    
			max = xm[i];
		}
		if(max.tickets == xm[i].tickets)
		{
    
            max1 = xm[i];
		}
	}
	if((strcmp(max.name,max1.name)!=0)&&(max.tickets == max1.tickets))// There is a case that the situation of the same number of voters is announced separately 
	{
    
		printf("%s and %s With %d Votes were elected at the same time ！！ The invalid ticket is %d\n",max.name,max1.name,max1.tickets,feiPiao);
	}
	else{
    
		printf("%s With %d Elected by ballot ！！ The invalid ticket is %d\n",max.name,max.tickets,feiPiao);
	}
	return 0;
}

give the result as follows ：
The highest number of votes

The same number of votes

It confirms the fact that the higher vote wins

There's another way to write it

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

struct XuanMin
{
    
	char name[32];
	int tickets;
};

struct XuanMin* initXms(struct XuanMin *p,int *pn)
{
    
	
	int i;
	if(p == NULL){
    
		printf(" Please enter how many people are running ：\n");
		scanf("%d",pn);
		p = (struct XuanMin*)malloc(*pn*sizeof(struct XuanMin));
	}
	
	for(i=0;i<*pn;i++){
    
		p->tickets = 0;
		printf(" Please enter the first %d The name of a voter ：\n",i+1);
		scanf("%s",p->name);
		p++;
	}
	return p-*pn;
}

void printXms(struct XuanMin *p,int len)
{
    
	int i;
	for(i=0;i<len;i++){
    
		printf(" name ：%s, Number of votes ：%d\n",p->name,p->tickets);
		p++;
	}
}

int doVot(struct XuanMin *p, int len)
{
    
	int i;
	int j;
	int feiPiao = 0;
	int mark;
	char tmpName[32];
	struct XuanMin *pbak = p;
	
	for(i=0;i<5;i++){
    
		
		mark = 0;
		printf(" Please enter who you vote for ：\n");
		memset(tmpName,'\0',sizeof(tmpName)); // Empty it every time 
		scanf("%s",tmpName);// Enter the name of the selected voter , Like opening a ballot , See the same name 
		p = pbak;
		for(j = 0;j<len; j++){
     // Get the name , The number of votes of the corresponding candidate plus 1
			if(strcmp(tmpName, p->name) == 0){
    
				p->tickets++;
				mark  = 1;	
			}
			p++;
		}
		if(mark == 0){
    
			printf(" There is no such candidate , give up \n");
			feiPiao++;
		}
		
	}
	
	return feiPiao;
}

struct XuanMin* getMax(struct XuanMin *p, int len)
{
    
	struct XuanMin* max;
	int i;
	
	max = p;
	
	for(i=0;i<len;i++){
    
		if(max->tickets < p->tickets){
    
			max = p;
		}
		p++;
	}
	
	return max;
}

int main()
{
    
	struct XuanMin *xm = NULL;
	struct XuanMin *final;
	int total = 0;
	xm = initXms(xm,&total);
	printXms(xm,total);
	
	int feip = doVot(xm,total);
	printf(" The number of invalid tickets is ：%d\n",feip);
	printXms(xm,total);
	
	final = getMax(xm,total);
	printf("%s With %d Elected by ballot ！！ The invalid ticket is %d\n",max->name,final->tickets,feip);
	return 0;
}
