摘要：
1.Linux/Windows便携式#include<；intmain（）｛FILE*fp；result“；test_”；charlog[64]=｛0｝；fp=fopen（“./csvtest.csv”，“wb”）；}fclose（fp）；}2.在Linux下，您也可以直接使用system（）#include<；标准工时>；#包括<；
逗号分隔值（Comma-Separated Values，CSV，有时也称为字符分隔值，因为分隔字符也可以不是逗号），其文件以纯文本形式存储表格数据（数字和文本）。
1、linux/windows 可移植
#include <stdio.h> int main() { FILE *fp; char const *fileTitle = "num,test content,result "; char const *log_body = ",test_"; char const *seprate = ","; char const *log_tail = " "; char log[64] = {0}; fp = fopen("./csvtest.csv","wb"); fprintf(fp,fileTitle); for(int i = 0; i < 10; i++) { if(i%2 == 0) sprintf(log,"%d%s%d%s%d%s",i,log_body,i,seprate,0,log_tail); else sprintf(log,"%d%s%d%s%d%s",i,log_body,i,seprate,1,log_tail); fprintf(fp,log); } fclose(fp); }
2、linux 下也可以直接使用system()
#include <stdio.h> #include <stdlib.h> int main() { char log[64] = {0}; char const *log_head = "echo "; char const *log_body = ",test_"; char const *seprate = ","; char const *log_tail = " >> ./csvtest1.csv"; system("echo num,test content,result >> ./csvtest1.csv"); for(int i = 0; i < 10; i++) { if(i%2 == 0) sprintf(log,"%s%d%s%d%s%d%s",log_head,i,log_body,i,seprate,0,log_tail); else sprintf(log,"%s%d%s%d%s%d%s",log_head,i,log_body,i,seprate,1,log_tail); system(log); } }
