files

The fwrite(const void *buffer, size_t size, size_t count, FILE* stream) function is probably what you''re looking for.

To write a float to a file with this function you need code that goes something like this:


float myFloat;

// open the file for binary write
FILE* pFile = fopen("filename.dat","wb");

// write the float
fwrite(&myFloat,sizeof(float),1,pFile);

// close our file
fclose(pFile);



Hope this helps,

thx
but i want to save it to a normal .txt - file.
now, when i save it and then look at the file, there are just weird symbols.
does anybody know a other way????

i suppose you could use fprintf() and fscanf()

// to write FILE *file = fopen("filename.dat","w"); fprintf(file,"%f",myFloat); fclose(file); // // // to read FILE *file = fopen("filename.dat","r"); fscanf(file,"%f",&myFloat); fclose(file);
