warning C4267: '=' : conversion from 'size_t' to 'int', possible loss of data

hi

working on a project, and VS2005 is giving me this warning:
- warning C4267: '=' : conversion from 'size_t' to 'int', possible loss of data

the warning leads here:

Code:

---

tam = strlen(texto[n]);

---

can anyone tell me how to "fix" this warning?

Use size_t as your variable type instead of int.

Code:

---

size_t len;
...
len = strlen("bleh");

---

hey MacGyver!

i did what you said, but now it's giving me this warning:
- warning C4018: '<' : signed/unsigned mismatch

and now the warning leads here:

Code:

---

for(l=0; l<(71-tam); l++)

---

??

I bet you haven't set l as a size_t as well.

If l is already an unsigned type, then it might be worrying about 71-tam possibly being negative. You can always rewrite the condition like this:

Code:

---

for (l=0; 1+tam<71; l++)

---

Or like this, a more optimized version:

Code:

---

for (l=0; tam<=71; l++)

I think this is why you should never use lower case 'L' as a variable name if you can help it. ;)

I agree, use an uppercase 'i' instead ;)

hey you all!

i havent set 'l' as site_t, i'm going to try that, and if doesn't work i'm going to apply one these versions :)

Code:

---

for (l=0; 1+tam<71; l++)

---

Code:

---

for (l=0; tam<=71; l++)

---

The second version is wrong (I guess you didn't get the joke).

ehehe!
I know it was :P

i've seted the variables to size_t and it worked...tnx alot guys!

buy the way, what does this warning mean?
- warning C4013: 'menuLogin' undefined; assuming extern returning int

every time i reference a function that warning apears :(

It means you have no prototypes, or you are not including the .h where the prototypes are.

hi brewbuck!

i've done what you said, and it worked with the menuLogin function. But with the other functions it didn't :(
know i gives me these warnings:
- warning C4024: 'titulos' : different types for formal and actual parameter 1
- warning C4047: 'function' : 'char **' differs in levels of indirection from 'char *(*__w64 )[1]'

I don't know if I'm the only one growing tired of playing 20 questions here.

If you had stripped the base code down into a minimal compilable snippet you'd have had an answer days ago. It might be worth 20 minutes to try to do so now.

geatings dave!

nevermind the last question brewbuck, i've resolved it :)
thanks anyway for the help.
