file - Read comma separated values with stray whitespaces from a textfile in c++ -

i have file contains string,int,int values in multiple lines.

delhi,12,13 mumbai,100 , 101 kolkata,11,  12 

the values separated commas there can stray whitespaces in between.my current code :

 #include<cstdio> #include<iostream> #include<string>  using namespace std;   int main() {      file *f = fopen("input.txt","r");     int lines = 0;     char c = getc(f);     while(c != eof)     {         if(c == '\n')         {             lines++;         }         c = getc(f);     }     lines++;      string arr[lines];     int t1[lines];     int t2[lines];      char s1[100],s2[100],s3[100];     int x,y;     fclose(f);     f = fopen("input.txt","r");      while (fscanf(f,"%99[^,],%99[^,],%99[^,]", s1, s1, s2)==3)     {         cout << s1 << s2 << s3 << endl;     } } 

this doesn't seem quite read values , display on screen first of all. how read string , integer values here(which may have stray whitespaces) , store them array (three arrays precise) ?

try doing this:

   fscanf(f,"%[^, ]%*[ ,]%d%*[ ,]%d ", s1, &x, &y); 

%[^, ] => searches except , , <space> , stores in s1

%*[ ,] => searches , , <space> not store anywhere (the * ensures that)

%d => stores number
