error #2168: Operands of '=' have incompatible types 'char' and 'char *'

[net2011]

Hi everyone. I tried binging and googling this one and I found answers in forums that I don't think applied to my problem. When I try running this code

// Printing of characters & strings

#include <stdio.h>

void main()
{
   char x = "A";
   char name = "Eritrea";

   printf("output of characters\n\n");
   printf("%c\n", x);
   printf("%3c\n", x);
   printf("\n");
   printf("output of strings\n\n");
   printf("output of strings\n\n");
   printf("%s\n", name);
   printf("%20s\n", name);
   printf("%.5s\n", name);
   printf("%-10.2s\n", name);
}

I get this error message on both line 7 and 8. error #2168: Operands of '=' have incompatible types 'char' and 'char *'. The strange thing is this is the way they had it in the book I am studying ('C' Programming for Beginners). I am using Pelles C version 6.5.. If anyone can tell me what I am doing wrong I would be greatful. Thanks for the help.

try


#include <stdio.h>

int main()
{
   char *x = "A";
   char *name = "Eritrea";

   /*code*/

   return 0;
}

It worked but it didn't give me the desired output. The output was

output of characters

τ
  τ

output of strings

output of strings

Eritrea
             Eritrea
Eritr
Er
*** Process returned 11 ***
Press any key to continue...

and the desired output was

output of characters

A
  A

output of strings

output of strings

Eritrea
             Eritrea
Eritr
Er
*** Process returned 11 ***
Press any key to continue...

I don't know how many the process would've returned in that case. here is the code again

// Printing of characters & strings

#include <stdio.h>

void main()
{
   char *x = "A";
   char *name = "Eritrea";
      
   printf("output of characters\n\n");
   printf("%c\n", x);
   printf("%3c\n", x);
   printf("\n");
   printf("output of strings\n\n");
   printf("output of strings\n\n");
   printf("%s\n", name);
   printf("%20s\n", name);
   printf("%.5s\n", name);
   printf("%-10.2s\n", name);
}

Once again thanks for the help. How can I fix this?

I don't understand what are yow try to do ?

This program was really just meant do demonstrate the printing of strings and characters after assigning each to a variable so I was just looking to get the same output that was printed in the book refered to above.

After doing a bit of research I think strings are of type char* and single characters are of type char (correct me if I'm wrong) so after changing my code to

// Printing of characters & strings

#include <stdio.h>

void main()
{
   char x;
   char *name;

   x = 'A';
   name = "Eritrea";
      
   printf("output of characters\n\n");
   printf("%c\n", x);
   printf("%3c\n", x);
   printf("\n");
   printf("output of strings\n\n");
   printf("output of strings\n\n");
   printf("%s\n", name);
   printf("%20s\n", name);
   printf("%.5s\n", name);
   printf("%-10.2s\n", name);
}

I got the desired output refered to above.

I am just a beginner so if there is a better way to do it or if there is anything wrong, please let me know. It worked just fine when I ran it though. Thanks for the help.

You could have used

Code: [Select]

char x = 'A';
the problem was most likely the double quotes...

Single quote.... 1 character
Double quote ... string of characters with a 0 at the end.

#include <stdio.h>
#include <string.h>

int main()
{
   char plus = '+';
   char minus ='\x2d';

   char *one     = "One";
   char *two      = "Two";
   char three[6] = "Three";

/*if you want to print a single character*/
   printf( "\n    %c    char \n", plus );
    printf( "\n    %c    char \n", minus );

/*if you want to print a single character from string*/
   printf( "\n    %c    char from string \n", three[2] );

/*if you want to print all characters from  string*/
   for( int i=0; i < strlen(one); i++)
   {
    printf( "\nindex = %d    char = %c    \n", i, one );
   }
/*if you want to print a string*/
    printf( "\n    %s    \n", one);
/*and, (more complex) output*/
    printf( "\n    %s    %c   %s    =    %s ;\n", one, plus, two, three);
    printf( "\n    Three    %c   3    =    %.2f ;\n", minus, 0.0);

   return 0;
}
