A for-loop as a while statement?
Hi guys,
i'm having some troubles finishing my programm. My programm delete all files that have the same parameter.
So here i read the files and find a specific string:
Code:
if (datei = fopen(filepfad, "a+"))
{
while (fgets(buffer, sizeof(buffer), datei)){
vtNr = 0;
index = 0;
str_leng = my_strlen(buffer);
//So lange das der Teil String "vtNr" nicht gefunden wird, springt der buffer an die nächste Stelle.
//Wenn die letzte Stelle der Zeile erreicht wurde springt das Programm in die nächste Zeile.(Dokumentaiton zu fgets lesen)
while(!( buffer[index] == 'v' && buffer[index + 1] == 't' && buffer[index + 2] == 'N' && buffer[index + 3] == 'r') && index <= (str_leng - 3) )index++;
if ( index < str_leng - 3 ) {
while(!(buffer[index] >= '0' && buffer[index] <= '9'))index++;
while(buffer[index] >= '0' && buffer[index] <= '9') {
vtNr = vtNr * 10 + chartoint(buffer[index]);
index++;
}
fclose(datei);
if ( vtNr > 999999) vtNr_vergleichen(vtNr, filepfad);
}
}
In the while loop i check if the string is found, but i want that the user determined which string he is looking for. I thought do to it like something like this:
Code:
while( !( for(i=0 ; i < str_end ; i++) buffer[index + i] == str_looking [i]) ) index++;
str_end is the length of the string written by the user.
Thanks for your time :D.
