以写方式打开myfile.txt文本文件，正确的选项是（）。
A: fopen("myfile.txt","r");
B: fopen("myfile.txt","w");
C: fopen("myfile.txt","rb");
D: fopen("myfile.txt","wb");
A: fopen("myfile.txt","r");
B: fopen("myfile.txt","w");
C: fopen("myfile.txt","rb");
D: fopen("myfile.txt","wb");
举一反三
- 若有定义FILE *fp; 以“只读”方式打开文件C:\test\myfile.txt的正确语句是 A: fp = fopen("C:\test\myfile.txt","r"); B: fp = fopen("C:\\test\\myfile.txt","r"); C: fp = fopen("C:\test\myfile.txt",'r'); D: fp = fopen("C:\\test\\myfile.txt",'r');
- 要在D盘mydir目录下新建一个myfile.txt文件用于写,正确的语句是______。 A: FILE*fp=fopen(“D:\mydir\myfile.txt”,”W”); B: FILE*fp; fp=fopen(“D:\\mydir\\myfile.txt”,”W”); C: FILE*fp; fp=fopen(“D:\mydir\myfile.txt”,”r”); D: FILE*fp=fopen(“D:\\mydir\\myfile.txt”,”r”);
- 要在D盘MyDir目录下新建一个MyFile.txt文件用于写，正确的语句是（ ）。 A: FILE *fp=fopen("D:\MyDir\MyFile.txt","w"); B: FILE *fp; fp=fopen("D:\\MyDir\\MyFile.txt","w"); C: FILE *fp; fp=fopen("D:\MyDir\MyFile.txt","r"); D: FILE *fp; fp=fopen("D:\\MyDir\\MyFile.txt","r");
- 要在D盘MyDir目录下新建一个MyFile.txt文件用于写，正确的语句是（ ）。 A: FILE *fp=fopen("D:\MyDir\MyFile.txt","w"); B: FILE *fp; fp=fopen("D:\\MyDir\\MyFile.txt","w"); C: FILE *fp; fp=fopen("D:\MyDir\MyFile.txt","r"); D: FILE *fp; fp=fopen("D:\\MyDir\\MyFile.txt","r");
- 要在D盘MyDir目录下新建一个MyFile.txt文件用于写，正确的语句是（ ）。 A: FILE *fp=fopen("D:\MyDir\MyFile.txt","w"); B: FILE *fp; fp=fopen("D:\\MyDir\\MyFile.txt","w"); C: FILE *fp; fp=fopen("D:\MyDir\MyFile.txt","r"); D: FILE *fp; fp=fopen("D:\\MyDir\\MyFile.txt","r");
