#include <stdio.h>
#include <stdlib.h>
int main()
{
int n, i, number;
char subject[30];
FILE *fp;
if((fp = fopen("input.txt", "r")) == NULL)
{
printf("Error opening file.\n");
exit(1);
}
fscanf(fp, "%d", &n);
for(i = 0; i < n; i++)
{
fscanf(fp, "%s", subject);
fscanf(fp, "%d", &number);
printf("%s %d\n", subject, number);
}
fclose(fp);
return 0;
