P: n/a
Just starting with C, can somebody explain why this does not work or
point me in the right direction? I wrote some tools and did some
coding but cant seem to get this one. I DID declare my FILE *fp! and
still get..
isource2.c: In function `getval':
isource2.c:5: `FILE' undeclared (first use in this function)
Here is my Example project:
$ls
Makefile file1 isource2.c isource2.h source1.c
$cat source1.c
#include <stdio.h>
#include 'isource2.h'
main()
{
int val;
val = getval();
printf('in main: %dn', val);
}
$cat isource2.c
int
getval(void)
{
FILE *fp;
int val;
fp = fopen('file1', 'r');
fscanf(fp, '%u', &val);
printf('in getval: %dn', val);
fclose(fp);
return (int) (val);
};
$cat isource2.h
int getval(void);
$cat file1
50
$cat Makefile
testtool: source1.o isource2.o
gcc -o source1 source1.o isource2.o
source1.o: source1.c isource2.h
gcc -g -c source1.c
isource2.o: isource2.c
gcc -g -c isource2.c
$make
gcc -g -c source1.c
gcc -g -c isource2.c
isource2.c: In function `getval':
isource2.c:5: `FILE' undeclared (first use in this function)
isource2.c:5: (Each undeclared identifier is reported only once
isource2.c:5: for each function it appears in.)
isource2.c:5: `fp' undeclared (first use in this function)
make: *** [isource2.o] Error 1
Don't understand, please explain - this should work, according to me
it's straigt forward! Isn't it????

Format Identifiers The format identifier describes the expected data. The identifier is the character that ends Here is a list of the format identifers as used in 'printf','sprintf','fprintf' and 'scanf'. Except for '%' and 'n', all the identifiers expect to extract an argument from the printf parameter list. Sara cooking games chicken biryani download. Hmm I'm still fairly new to c myself only 3 weeks in and I haven't had to use that header for my programs yet. With problem 2 your are typing a meal out but what you are telling your program with int is that you would input a. You're Welcome. Also, with my experience with DevC, getting 3rd party libraries are a pain. This is just a suggestion, but if you are unhappy with DevC, try CodeBlocks IDE. C언어 강좌3: 출력(printf), dev c 사용방법.

Int main (void) And that won't make any difference if you try to call a function that doesn't exist in the library of the compiler you're using.
