Thread: If and get; really short post, help!

This is my program:

Code:

#include <stdio.h>

void main()
{
	char love[20];


	printf("Insert the name of the person that you love. \n");
	gets(love);
	
	if(love == "Lisa") 
	{	 printf("\n Wonderful, because %s loves you too!", love);
	}
	else if(love == "Alex") 
	{	printf("\n Wonderful, because %s loves you too!", love);       
	}
	else 
	{	printf("\n Error! \n You do not love %s.", love);
	}
	
}

However, when run on Quincy 2000 I receive errors, and my first two "If" statements do not work. Everytime I type in a name, it automatically goes to the third if statement.
Also, my error says something about "the return value for main is not int". But I don't have a return value, nor do I have any integers.

What is the problem?
Thank you.

you have to call the function strcmp() to compare two strings.

Code:

if( strcmp(love,"Lisa") == 0)
{
   // the strings are equal
}

Never heard of Quincy 2000 but maybe your code should look like this:

Code:

#include <stdio.h>
#include <string.h> //  Needed for stricmp
void main()
{
	char love[20] = {0};
	printf("Insert the name of the person that you love. \n");
	gets(love);
	
	if(stricmp(love,"Lisa") == 0) 
	{
	printf("\n Wonderful, because %s loves you too!", love);
	}
	else 	if(stricmp(love,"Alex") == 0)  
	{
	printf("\n Wonderful, because %s loves you too!", love);       
	}
	else 
	{
	printf("\n Error! \n You do not love %s.", love);
	}
}

There is no such standard function as stricmp. And again, main needs to return int, not void.

Yep, you're right about gets and main return but stricmp is the Win32 version of strcasecmp in the Linux and *nix world.

Been using it for years in all sorts of Win32 projects, hasn't failed me yet.

Code:

#include <stdio.h>
#include <string.h>
int main()
{
	char love[20] = {0};
	printf("Insert the name of the person that you love: \n-> ");
	gets(love);
	
	if(!strcmp(love,"Lisa")) 
	{
	printf("\n Wonderful, because %s loves you too!", love);
	}
	else 	if(!strcmp(love,"Alex"))  
	{
	printf("\n Wonderful, because %s loves you too!", love);       
	}
	else 
	{
	printf("\n Error! \n You do not love %s.", love);
	}
	gets(love);
	return 0;
}

As its a int you need to put a return 0; at the end. Also the gets before the return will stop thw window closing before you get to read the ouput.

Ansi C standards bring back fond memories of writing DOS console apps. Being a contract programmer, I just can't remember the last time a potential employer asked me if I was knowledgeable in ANSI C standards. Nowadays, skillset requirements are Windows GUI, COM, DCOM, Graphics/Animation etc. There is now a serious demand developing for C# programmers. And the only C# standard is the Bill Gates standard.

All of the high end stuff C stuff I worked on would never meet ANSI C standards.

The point I'm trying to make is that standards are nice but I wouldn't get in a tither over them.

BTW I have K&R's The C Programming Lanuage. It's been superceded by Petzold on Windows, Russinovich on Windows Internals, Hart on Systems Programming etc.

we are in the presence of a contract programmer, I am unworthy.

-seriously no sarcasm intended.

And educational institutions are one of the biggest offenders. I can't count the number of times students are required to learn programming with 15-year-old, obsolete compilers such as Tucbo C, then the students can't understand why the functions in conio.h and dos.h don't work with modern 32-bit compilers!
