How do you create a ".log” file in C?

Question

I need to create .log file using C. However, I cannot use the usual way to create this. The file is created but it cannot write. Can anyone explain?

f = fopen("file.log", "w"); 

fprintf(f, "print this");

In Linux, it is pretty simple to create a .log file:

Create a file using the code given below in the same folder where you have placed your C code.

FILE *fp; 

fp = fopen ("data.log", "w"); 

fprintf(fp, "print this");

Path can also be specified where you want to create your file. 

FILE *fp; 

fp = fopen ("E://data.log", "w"); 

fprintf(fp, "print this"); 

}
