c语言计数器

Posted 2023-03-09

求一个选举统计的c语言程序代码......刚开始界面是“请输入选票上的号码：”。输入号码后回车，然后不断有“请输入选票上的的号码：”。输入“0”回车后自动统计每个号码得票次数。谢谢！

c52开发版计数器c语言,C语言的简单计数器

现在在读写文件时不用fscanf和fprintf，使用fgetc和fputc该怎么该啊、

#include "stdio.h"

#include "stdlib.h"

#define FilePath "counter.dat"

int readCounter(char* path);

void writeCounter(int count , char* path);

void main()

{

int count=0;

count=readCounter(FilePath)+1;

printf("该程序已运行:%d\\n",count);

printf("-----------------------------------\\n");

printf("下面将运行次数写入计数器文件(counter.dat)....\\n");

writeCounter(count,FilePath);

printf("写入文件结束！\\n");

printf("程序运行结束！\\n");

printf("-----------------------------------\\n");

system("pause");//程序暂停

}

int readCounter(char* path)

{

FILE* fp;

int count;

if((fp=fopen(path,"r"))==NULL)

{

printf("没有计数器文件:count.dat,保存运行次数时将新建该文件！\\n");

return 0;

}

fscanf(fp,"%d",&count);

fclose(fp);

return count;

}

void writeCounter(int count , char* path)

{

FILE *fp;

if((fp=fopen(path,"w"))==NULL)

{

printf("无法创建计数器文件！\\n");

return ;

}

fprintf(fp,"%d",count);

fclose(fp);

}
