I am trying to do duplicate elimination from clients.txt (which has 7 names and surnames, some of them are repeated). In the end of file it writes the output to output.dat file. I did not get any error during the compiling but when i try to run it, it gives "003.exe stopped working" error. (003.c is C project name)
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
struct names
{
char name[25];
char surname[25];
};
int main()
{
int i, j;
char a[1] = {""};
struct names name[200];
FILE *file;
FILE *file2;
file = fopen("clients.txt", "r");
if (ferror(file))
{
printf ("File could not be opened");
}
while (fscanf(file, "%s", a) == 2)
{
i = 0;
fscanf(file, "%s %s", name[i].name, name[i].surname);
i++;
}
for (i = 0; i < 200; i++)
{
for (j = 0; j < 200; j++)
{
if (i != j && strcmp(name[i].name, name[j].name) == 0 && strcmp(name[i].surname, name[j].surname) == 0 )
{
strcpy(name[j].name, a);
strcpy(name[j].surname, a);
}
}
}
fclose(file);
file2 = fopen("output.dat", "w");
{
for (i = 0; i < 200; i++)
{
if ( strcmp(name[i].name, "") == 1 )
{
fprintf(file, "%s %s\n", name[i].name, name[i].surname);
}
}
}
fclose(file2);
system("pause");
return 0;
}
