Hi all

i just wanted to kno how to multiply every second digit by 2 or 3?

and then check if its in increasing order


so its:
//first scan the user input

num[i]= n;

/* now how to multiply the 2nd by 2 ? */

checking if its order:

if(num[i] > num[i+1]){
etc....

also is there any website that shows how to read a file and search the file WITHOUT USING THE STRING.H LIBRARY?

thanks
