how to take input from space separated integers in c/c++?

Question

first line contains an integer N. Each of the next N lines contains at least 1 and at most 100 space separated distinct integers(DEPENDS ON USER CHOICE). For ex-

3
5 100 1
2
5 100

i want to store nos in a 2d array like
a[1][1] = 5 , a[1][2] =100, a[1][3] = 1
a[2][1] =2
a[3][1] = 5, a[3][2] = 100

In C, you can use the strtok() function.

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

int main()
{
   char str[80], first[12];
   char *token;
   int num, n, i;
   int ara[100][100]; // whatever size you want

   get(first);
   n = atoi(first);

   for (i = 1; i <= n; i++) {
     gets(str);
     token = strtok(str, " ");

     while( token != NULL ) 
     {
        num = atoi(token);
        printf( "%d\n", num );

        token = strtok(NULL, " ");
     }
   }

   return 0;
 }
