Hi, i have a problem. i have a file that there is a line in the file : #include "hello.h" i have to open the "hello.h" file and copy it to another file. i did : char getline[MAX_LINE]; char *fp1; fp1 = strchr(getline2,'#'); /* fp1 = #include ..., taking the include from the line */ fp1 = strchr(fp1,'"'); /* fp1 = "hello.h" */ FILE *file = fopen(fp1,"w"); the file hello.h is in the main libary and the file not opened. i hope i was understandable, and if someone can help me i`ll appreciate it. Thanks, Or.
You need to created a file stream to open the file. Try the code below I'm rusty in C++ but to open a file you need to create a new fstream, you also need to include fstream, and istream if you want to read and open the file. In C you would use fopen and fread functions instead. Make sure your directory for the hello.h is correct that maybe why its not being included and causing the compile error. Code: #include<fstream> #include<istream> #include<ostream> use name space std; int main() { fstream file; // create new file stream file.open("hello.h"); // open file char contents = file.getline();// get all contents till end of file cout<<contents<<endl; // print the files content to the cmd prompt }
