How to print instead of \t the number of spaces that i determine *using files * in c?

using C,Converting each \t to a number of spaces ... Ex ,if my tabs.txt contains

This file has. too many. tabs. where each space above is actually a \t character, then the file myspaces.txt should look like the following if n=2, This. file has too many tabs. can my if statment be like if (c=='\t') then i d print a space ? i do have the code but its not runnging dunno why :-/

#include<stdio.h>

#include<stdlib.h>

int main()

{

char d;

FILE * fin = fopen("mytabs.txt", "r");

FILE * fout = fopen("myspaces.txt", "w");

int n;

printf("Enter n: ");

scanf("%d", &n);

while(fscanf(fin, "%c" ,&d)!=EOF)

{

if(d =='\t')

{

for(i=0;i<n;i++)

{

fprintf(fout , " ");

}

}

else {

fprintf(fout, "%c", d)

}

}

fclose(fin);

fclose(fout);

system("pause");

return 0;

}
