How can I make that the do-while keeps repeating while the user hasnt entered anything?? I mean, if when asked to enter your name you just press ENTER then the do-while repeats... I have this code but it doesnt work!!
Can you help me?
Code:void pidenombre(void) { do{ printf("Your name?"); gets(nombre); }while(nombre=="\0"); }
---Programming is like roaming, you never know where you'll end at------
If 'here' is pronounced as 'hear', why 'there' isnt pronounced as 'dear'??

You should be trying to capture a new line not a null terminator. so use '\n' instead of '\0'.

}while(nombre=="\0");
Is wrong. You are trying to compare strings but instead are comparing their addresses. Try this instead:
ORCode:}while(nombre[0]=='\0'); /* Check the single quote ' */
>You should be trying to capture a new line not a null terminator. so use '\n' instead of '\0'.Code:}while(!strlen(nombre));
gets() breaks when it encounters a '\n', which is not returned in the string, so, checking for '\n' is not going to help you

You all have overlooked the most obvious flaw: they're actually using gets! Never use gets. Use fgets instead. It's safer.
Quzah.
Hope is the first step on the road to disappointment.
