scanf - Using Delimiters for 'fscanf' in c -

i trying read file in c in way load simple variables , values. example, let's text of file:

a=100 b=hello c=world 

ow idea load each line of file such string on left of equals sign name of variable, , string on right loaded in value. code read file in way described:

#include <stdio.h>  int main(void) {     file* f;     f = fopen("test.txt", "r");      char name[256];     char value[256];      while(fscanf(f, "%255[^=]=%255[^=]", name, value) == 2)         printf("%s, %s\n", name, value);      return 0; } 

but when compile , run it, output is:

a, 100 b 

i should mention have basic grasp of how delimiters work in scanf or fscanf formatting strings. have feeling that's what's going wrong here, have yet find or stumble upon solution. appreciated!

%255[^=] read = on first line = on second line, since didn't include newline delimiter. it's setting name "100\nb". next fscanf() fails because there's no string before =.

use newline second delimiter rather =, , put space before first format skips on whitespace before parsing each line.

while(fscanf(f, " %255[^=]=%255[^\n]", name, value) == 2)
