still working on this. i changed the <list.h> to "list.h" which gave me a bunch new errors. they're all "undefined reference to 'some function'", but all my functions are defined in list.h. (yes, list.h is in the correct director with the other two files) so how do i fix the "undefined reference" problem? i am honestly not getting this.

here are my compiler errors

debugging help please in C
I have three files list.c list.h driver.c. they dont compile properly (they are to be compiled together). i can't find my assignment specs right now, i'll try to post them soon. but maybe someone can make sense of this w/o my instructions?
...Code:list.c #include <stdio.h> #include <stdlib.h> #include <string.h> #include "list.h" #define LISTSZ(a) (((a)-1)*sizeof(char*)+sizeof(struct

reading two lines from stdin using fgets
i have the following code which works just fine:
printf("Enter a string: \n");
fgets(ch, 1024, stdin);
but i need it to read two lines. this quits as soon as i hit the enter key. how can i fix this up to allow two lines? -
//I made some changes and made comments. note the error messages at the

void sreplace(char newc, char oldc, char *s){
while(char *s != '\0'){
*s= oldc; //setting *s to the first character in the array
if(*s = newc){//
oldc=newc; //change oldc to newc
}
s++; //increment *s every time through the loop
}
return;...Leave a comment:

this won't compile
***instructions : write a function sreplace( ) with the prototype:
void sreplace(char newc, char oldc, char *s);
which will replace all occurances of the character oldc with the character newc in the string s. there is no return value so merely do a return***
I *think* this code makes sense. but it wont compile. please help. thank you.

string match function
in C, write a function [char *strmatch(char *str, char *s)]
which will find the first occurance of the string s in the string str and will return a pointer to the first match if such a match occurs. if there is no match, then strmatch() should return NULL
Here is what i came up with. am i close?
char *strmatch(char *str, char *s)
while (char *str != '\0'){
if (*str == *s){
return... -
i am posting again hopefully some one can help?
the assignment is as follows: write a c program that will read from stdin (using getchar()) and replace tabs by the number of blanks that will achieve the same spacing. (8 spaces in a tab)
here is my code, what i came up with:
...Code:#include <stdio.h> int main(void) { char ch, tab; int c;Leave a comment:

convert tabs to spaces
my assignment is to convert tabs to spaces (8) in C. we are supposed to use getchar() and not expand(). can someone get me started? it should be REALLY simple so i can grasp it!
Thanks
