Write a program to print stuff to a file reading the number of time

#include "stdio.h"
#include "stdlib.h"
#include "unistd.h"

void writefile(char *);

int main()
{
int N;
FILE *inf;
int i;

inf = fopen("infile.txt", "r");

/* Now let us read the number from a file */
fscanf(inf, "%d", &N);

for(i = 0; i <>
writefile("WWW");

printf("
");
fclose(inf);
return(0);
}

void writefile(char *str)
{
FILE *outf;
int i;

outf = fopen("outfile.txt", "a");

/* Now let us write to the file */
fprintf(outf, "
%s", str);

fclose(outf);
