lets say i have a long type variable
for exampleim looking for the best algorithm to put 111 for example at the left of the number(Code:long x =43343539839853583;Code:final result 11143343539839853583)

So I guess we're assuming that a long is 64 bits? I would just do this: x += 11100000000000000000;
If you understand what you're doing, you're not learning anything.
If the number of digits will vary, then you need to look into using log10 to figure out the number of digits (or a division loop), and pow to get something to multiply it by to get the right number of zeros after the 111. Then you can add.

Convert to string, stick "111" at the front, convert back to long?
Code://try //{ if (a) do { f( b); } while(1); else do { f(!b); } while(1); //}
Like this...
Brewbuck had the right idea...Code:char str[32] = "111"; sprintf(&str[3],"%d",number); number = stoll(str);
