I have been trying unsuccessfully to read in a text file and skip over specific characters - something like what C++ does with cin.ignore().
I need to skip over characters like ';' and '->'.
I hope someone can help me..

What is the function that you use to read the text file?

If you use getc(), then you can check the variable and omit from your manipulation like this:
Code:
#include <stdio.h>
int main()
{
char c;
FILE *fp;
fp = fopen("sample.txt","r");
while((c = getc(fp)) != EOF)
{
if(c == ';' || c == '-' || c == '>')
continue;
else
printf("%c", c);
}
fclose(fp);
return 0;
}

Welcome.
![]() In case your input file contains the '-' and '>' characters, they will also be omitted from reading along with the '->' symbol. I have given you an idea of how to do the skipping of characters, you should take care of the case that I mentioned here while omitting the characters. |
