The StreamWriter constructor takes the name of the file to be created. If the file exists, it is overwritten (unless you pass True as the second StringWriter constructor argument). The file is then filed using the Write and WriteLine functions. Example 复制 // text_write.cpp // compile ...

Keep in mind that you should close the file with the fclose function before the program exits. #include <stdio.h> #include <stdlib.h> #include <string.h> const char* str = "Temporary string to be written to file!"; int main(void) { const char* filename = "out.txt"; FILE* ...
