what are you A,B of type integer declaring for??

9 times assigning a random value in nRanda, purpose?

better devlare this A at start of main, instead ofstrange A,B of type
integer.

Man, B must be a string, an array of chars!!!Not a character.

 Here look, a code for generating random filename into FileName:

char FileName[13];
int i;

for (i=0;i<8;i++) FileName[i]=rand()%('z'-'a'+1)+'a';
FileName[8]='.';
for (i=9;i<12;i++) FileName[i]=rand()%('z'-'a'+1)+'a';
FileName[12]='\0';

thats it.
