#include <stdio.h>
FILE * fout=NULL;
int main()
{
fout=fopen("filename.tex","w");
for(int i=0;i<=20;i++){
fprintf(fout,"Hello World\n");
}
}
利用程式碼來用檔案寫出東西
#include <stdio.h>
FILE * fout2=NULL;
FILE * fin2=NULL;
float angle[20];
int main()
{
fout2=fopen("motion.tex", "w+");
for(int i=0;i<=20;i++){
fprintf(fout2," %.2f", angle[i]);
}
}
用程式開檔案
