Thread: Cut a string

I have just do a program to cut a string to 2 string, space by tab, but when I run it was failed, could you fix help me?
the data.txt file have multilines, a line include a word, a tab and a word

Code:

void main()
{
    clrscr();
    FILE*f;
    char*tr;
    char chuoi[100];
    char*dau;
    char*cuoi;
    int length;
    f=fopen("E:/data.txt","r+");
    while(!feof(f)-1)
    {
	fgets(tr,100,f);
	strcpy(chuoi,tr);
	dau=strtok(chuoi,"\t");
	for(int i=0;i<(strlen(tr)-1);i++)
	{
		if(tr[i]=='\t')
		{
			strcat(cuoi,&tr[i+1]);
		}
	}
	printf("%s",dau);
	printf("-%s",cuoi);
	strcpy(chuoi,"");
	strcpy(dau,"");
	strcpy(cuoi,"");
    }
    getch();
}

I want to take each line to give in database, so, i use foef

Can you give me some informations about sscanf function? I don't know it.

Is there a function which cut string from a string to a character?
