How to select and print the specifc first word from file?

Question

See more:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define STRING_LEN 200

int main(){
  char string[STRING_LEN];
  FILE * fp1 = fopen("file.csv", "r");
  char * data[2];
  char * line = NULL;
  int i = 0;

  while(fgets(string, STRING_LEN, fp1)){
    data[i] = strtok(string, ",");
    printf("data[%d] = %s\n", i, data[i]);
    i++;
  }
  return 0;
}

What I have tried:

This code is reading the first word (e.g. first & the last name but considered as one word with the difference of comma) from each line but how can I select the specific one? like I just want to print the data[1] or just want to print data[0]

The result it's giving me

data[0] = Bilal Khan
data[1] = Ali Ahmed
data[2] = Michael Jackson

We have offered a number of suggestions in your previous posts of this same question. Please go back and review them, including the code samples. If you have a specific problem with any offered solution then please post a reply to that message and explain what does not work.

Also, your code above is wrong:

C++

while(fgets(string, STRING_LEN, fp1)){
    // you do not need an index value since you are only trying to print the first field of each line
    char* data = strtok(string, ",");
    printf("data = %s\n", data);
//    i++;
}
