C - how to input this line

Question

I'm trying to take as input of a struct this kind of line "1 Myke Tyson 1234567891"

What is the best way to do this?

This is what I tried:

scanf("%d", &list.n1);
fgets(list.name, 14, stdin);

for(i = 0; i < 10; i++)
{
    scanf("%d", &list.n2[i]);
}

EDIT: This is the struct:

   struct ex{
         int n1;
         char name[14];
         int n2[10];
   }

Answer 1

Use fgets() , sscanf() and additional code to parse.

This parsing would be more robust if the separator (a space) was not allowed in a field. The potential space or spaces within .name convoluted the parsing. Recommend comma separated fields. Further the int n2[10] field is unusual. Why not unsigned long long n2 ?

Be sure to check result of fgets() , sscanf() .

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

typedef struct ex {
  int n1;
  char name[14];
  int n2[10];
} ex;

int ReadEx(ex *dest) {
  char buf[20 + 1 + 14 - 1 + 1 + 10 + 2];  // Or use something big like buf[100]
  if (fgets(buf, sizeof buf, stdin) == NULL ) {
    return -1;  // EOF or I/O Error
  }

  char name[14 + 1]; // temp place for name and final space separator
  int p1, p2;        // Offset for beginning and end of n2 array
  unsigned long long ull;  // Dummy to save n2 array
  if (3 != sscanf(buf, "%d %14[A-Za-z ]%n%llu%n", 
      &dest->n1, name, &p1, &ull, &p2)) {
    return 1; // format error
  }

  // strlen(name) cannot have the value of 0 here as sscanf() is 3
  size_t SpaceIndex = strlen(name) - 1;
  if ((name[SpaceIndex] != ' ') || ((p2 - p1) != 10)) {
    return 1; // format error, space expected at end of name and 10 digits
  }
  // name cannot contain only spaces due to the space before %14
  while (name[SpaceIndex] == ' ') {
    name[SpaceIndex--] = '\0';
  }
  strcpy(dest->name, name);
  int i;
  for (i = 0; i < 10; i++) {
    dest->n2[i] = buf[p1 + i] - '0';
  }
  return 0;
  // One could use the below approach but it is not so extensible.
  // if (12 != sscanf(buf, "%d %14[A-Za-z ]%1d%1d%1d%1d%1d%1d%1d%1d%1d%1d %c",
  //   &dest->n1, name, &dest->n2[0], &dest->n2[1], ... &dest->n2[9], &dummychar)) {
}

One of the possible way is

struct ex{
     int n1;
     char name[14];
     char n2[11];
}

scanf("%d", &list.n1);
fgets(list.name, 14, stdin);
fgets(list.n2, 11, stdin);
