Question

i keep getting that error message for this line of code:
for (i = 0, fstatus = fgets(name, 10, file1);
i < 50 && fstatus != NULL;
i++, fstatus = fgets(name, 10, file1)) {

I guess I'll post the entire thing here:

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

int main()
{

char name[10], filename1[10], filename2[10];
char** names;
char* fstatus;
char* name_sized;
FILE* file1;
FILE* file2;

int i;

scanf("%s", filename1);

scanf("%s", filename2);

if ((file1 = fopen(filename1, "r") == NULL)) {
printf("Cannot open file %s. ", filename1);
return 1;
}

names = (char**) malloc(strlen(file1));

/*
* Read names from file, up to num_names or EOF, whichever occurs first.
*/
for (i = 0, fstatus = fgets(name, 10, file1);
i < 50 && fstatus != NULL;
i++, fstatus = fgets(name, 10, file1)) {

/*
* Allocate a string just the right size for name.
*/
name_sized = (char*) malloc(strlen(name));
strcpy(name_sized, name);

/*
* Store the sized name in the names array.
*/
names[i] = name_sized;
}

printf("%d", atoi(names[2]));

return 0;

}

Explanation / Answer

Hi,
your fstatus is a pointer to char and fgets returns a char. So, you are assigning integer to a pointer (and so the error message). I guess you can do this:

change fstatus to *fstatus while assigning.

#include
#include
#include

int main()
{

char name[10], filename1[10], filename2[10];
char** names;
char* fstatus;
char* name_sized;
FILE* file1;
FILE* file2;

int i;

scanf("%s", filename1);

scanf("%s", filename2);

if ((file1 = fopen(filename1, "r") == NULL)) {
printf("Cannot open file %s. ", filename1);
return 1;
}

names = (char**) malloc(strlen(file1));

/*
* Read names from file, up to num_names or EOF, whichever occurs first.
*/
for (i = 0, *fstatus = fgets(name, 10, file1);
i < 50 && fstatus != NULL;
i++, *fstatus = fgets(name, 10, file1)) {

/*
* Allocate a string just the right size for name.
*/
name_sized = (char*) malloc(strlen(name));
strcpy(name_sized, name);

/*
* Store the sized name in the names array.
*/
names[i] = name_sized;
}

printf("%d", atoi(names[2]));

return 0;

}
