hey wondering if you can help me
im trying to read in a file which contains 256 double floating point numbers.
im using scanf to do this.
my problem comes when i need to add random values to these numbers, which need to range between +15 and -15, at an interval of around 10-50 samples.
ive heard that 'int rand(void);' included in the library stdlib.h would be useful, but my knowledge of this function is rather limited!
any help would be gratefully appreciated. thank you
