linux/windows 双平台csv文件生成方法
标签:value char sprintf fopen result file values system 移植
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 int main()
{
FILE *fp;
char const *fileTitle = "num,test content,result\n";
char const *log_body = ",test_";
char const *seprate = ",";
char const *log_tail = "\n";
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
#include 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);
}
}
