c programming for loop increment <solved>

[docnascar]

for (initialize variable; test; increment)

Code: [Select]

for (i=0; i<=10; i++)I understand this will make "i" increment by counts of 1 until the loop is satisfied. However, how do I make it increment by 3?
Obviously this is wrong buy my intent is:

Code: [Select]

for (i=0; i<=12; i+3)

Also, can you call a function as the increment? I couldn't get that to work either.
Obviously this is wrong buy my intent is:

Code: [Select]

for (i=0; i<=12; somefunction(i))
printf ("%i\n", i);

return 0;
}


int somefunction (int x)
{
    return (x + 3);
}

I got the increment +3 part... (found it as a c++ command that works for c  )

Code: [Select]

for (i=0; i<=10; i+=3)
My question still stands on the function.

Code: [Select]

for (i=0; i<=12; somefunction(i))

int somefunction (int x)
{
    return (x + 3);
}


Your intent probably is:
for (i=0; i<=12; i = somefunction(i))
