Ok, so my problem is, I am trying to use sscanf to get a string and a floating point number, however for some reason it is missing the floating point number altogether. I used BOTH fputs AND printf in the following example to illustrate what IS getting scanned in, and what is SUPPOSED to be getting scanned in. I will include the output as well. Thanks for the help guys. (This is not the whole program, this is just the guts of the function), I NEED THAT FLOATING POINT NUMBER SCANNED IN! A list of things I have tried is at the very bottom too.
FILE *file_input;
file_input=fopen(filename,
"r");
if (file_input == NULL){
return 1;}
double a;
char string [100];
char temp_string[30];
while (fgets(string,sizeof(strin
g),file_in
put)!=NULL
){
sscanf(string,"%s\t%f",tem
p_string,&
a);
fputs(string, stdout);
printf("%s\t%f\n", temp_string,&a);
OUTPUT:

I've tried sscanf(string,"%s\t%f",tem
p_string,a
); but I get a segfault
Ive tried sscanf(string,"%s%f",temp_
string,&a)
; without the tab character still no luck
I've tried sscanf(string,"%s %f",temp_string,&a); with just a space and that doesn't work either.
